Outlook Clients not redirecting to new server

September 22, 2015, 9:08 am

We migrated from Exchange 2003 to 2010 without issue. Exchange 2003 has been removed from the environment

We are now currently Migrating from Exchange 2010 to Exchange 2013. Our setup is as follows:

1 2010 (on 2012) server with all roles installed

1 2013 server (on 2012 R2) with all roles installed.

We use split DNS, a forward and reverse proxy. Everything works fine here.

A UCC SAN certificate. No certificate errors 

Mail flow is working fine internally and externally.

When setting up a mailbox profile pointed to either server, the Outlook client resolves the name and server and configures the client just fine.

The issue we have is when we move mailboxes. If the user has the mailbox open, the get a prompt saying changes a have been made and they need to close and reopen. When they do that, they receive an error stating "MS Exchange is not available. Either there are network problems or the server is down for maintenance"

I can go into the users mail profile in Control Panel, repair the profile by changing the server name to the new server and all is well from there. I can"t see doing this for 2000+ users.

Autodiscover is set to our Exchange 2013 server both internally and externally

OWA & ECP for 2010 is set to https://owa2.domain.com/owa

OWA & ECP for 2013 is set to https://owa.domain.com/owa

Since we use iDevices on our network, OWA and ECP are set that way during the transition.

Outlook anywhere for 2010 is set externally to autodiscover.domain.com and blank for internal

Outlook anywhere for 2013 is set externally to OWA.domain.com and OWA.domain.com for internal

MAPI/HTTP for 2013 is set to https://owa.domain.com/mapi

MAPI/HTTP for 2010 is not applicable 

OAB for 2010 and 2013 is set to  https://autodiscover.domain.com/OAB

ActiveSync for 201 and 2013 is set tohttps://autodiscover.domain.com/Microsoft-Server-ActiveSync

EWS for 2010 is set to https://autodiscover.doamin.com/EWS/Exchange.asmx

EWS for 2013 is set to https://OWA.doamin.com/EWS/Exchange.asmx

Approximately 30-45 minutes after the move, the client will pick it up and redirect like it should.

I am figuring my issue is probably with Autodiscover but not sure where to start.

Exchange 2013 - Certificate - SAN list limit????

September 27, 2015, 7:55 pm

We support a larger number of domain in our environment and we just tried to consolidate all of our needed SAN names into a single certificate. Well, when we enabled the SMTP service on this certificate we received the error:

A Special RPC error occurs on server xxxxxxxx. The length of the property 4283 is too long. The maximum length is 4096.

Really vgue message and I cannot find mush about it when searching. My guess is that I will end up going from an all purpose certificate, to two certificates. One for SMTP services and one for web services, there fore splitting up the SAN names and shortening the length of the certificate.

Has anyone else come across this and have additional information?

Thanks!!   Tom

Configuring ADFS in a resources forest Exchange deployment with multiple account forests

Hello,

I am trying to configure ADFS 3.0 on Windows Server 2012 R2 for Single Sign on with Exchange 2013. There seems to be very little information regarding configuring ADFS in an Exchange resources forest deployment, so I am hoping someone has come across this and has a solution :)

The environment:

There are four forests in the environment, consisting of:

  • User forest 1 - user1.local
  • User forest 2 - user2.local
  • User forest 3 - user3.local
  • Resource forest 1 - resource.local

The resource forest contains all of the Exchange infrastructure.

The user forests contain all the corporate users who have have linked mailboxes in the resource forest.

Each user only has one account, which will exist in one of the 3 users forest, and use their employee ID numbers (e.g. ID12345) to sign in 

There is a one-way outgoing trust between the resource.local forest and each of the user forests. There are no trust between the user forests.

The problem:

I would like to configure ADFS for OWA to allow the corporate users in the users domain to access their mailbox . Please keep in mind that these users only have accounts the their respective users domain, and their account\"place-holder"AD object in the resource forest is disabled.

The ADFS farm will be deployed in the resource forest

Environmental Restrictions:

  • A two-way trust between the user forests and resource forest cannot be created
  • We cannot migrate to Office365
  • We cannot use Azure AD
  • A new forest containing all users cannot be created

My research on this suggests that I will need to:

  1. Deploy ADFS servers in each of the user forests
  2. Add the user forest's ADFS farm as Claims Provider Trusts in the resources ADFS environment
  3. Add the resource forest's ADFS farm as a Relying Party Trust in each of the user forest's ADFS farms
  4. Configure OWA (and ECP) as a Relying Part Trusts in the resource forest.

I have done the above, but this does not appear to be working. When I browse the OWA URL, I get the ADFS log on page listing each of the user forest (I believe these are integrated Identity Providers (IDPs) for each of the Claims Provider Trusts I created with the user forests). Selecting one of these and trying to signing in with a user's UPN returns the "Something went wrong" OWA message with the "UpnClaimMissing" ADFS error in the URL. All Claim Provider Trusts (in the resource ADFS) and the Relying Party Trusts (in the user forest all have teh 

Is this the correct approach? Should I be adding the user domains as attribute stores in the ADFS server in the resource forest instead (not sure about this one, but though I'd throw it out there anyway)?

Thank you

Outlook 2013 pop up warning after user has been migrated from EX2010 to EX2013

Hi guys.
Need some help regarding pop up window which is showing on user's Outlook 2013 after he has been migrated from Exchange2010 to Exchange2013.

Let's presume that this user is: USERNAME1, and what is even stranger to me, that pop up window is mentioning USERNAME2?

Both users USERNAME1, USERNAME2 has already been migrated from EX2010 to EX2013.

If I ran command " Get-ClientAccessServer | Select Name,AutodiscoverServiceInternalURI,AutodiscoverSiteScope | Fl " on Exchange2013 I get:

Name                           : EXCHANGE2010
AutoDiscoverServiceInternalUri : https://FQDN-exchange2010.domain.local/Autodiscover/Autodiscover.xml
AutoDiscoverSiteScope          : {SITE1}


Name                           : EXCHANGE2013
AutoDiscoverServiceInternalUri : https://FQDN-exchange2013.domain.local/Autodiscover/Autodiscover.xml
AutoDiscoverSiteScope          : {SITE1}

Both servers are using the same SAN certificate and they have:

FQDN-exchange2010.domain.local

FQDN-exchange2013.domain.local

autodiscover.domain.com

owa.domain.com

inside the cert.

I am a little bit confused / amuzed why that pop up window appears?

Cert seems to be ok because the mentioning address is in certificates SAN.

Outlook Anywhere is set up on Exchange 2013 and published thru TMG:

We haven't migrated all the users yet from Exchange 2010 to 2013.

We are on 80% now .

Please advise how to get rid of that nasty pop up.

With best regards

(Something Went Wrong) after Exchange 2013 setup

Hello experts,

We had one Win 2008R2 server acting as DC1 and hosting Exchange 2010 SP3. Now we have a new two virtual servers, one has been configured as DC2, and the other is hosting Exchange 2013 CU10. We plan to move all mailboxes to the new Exchange 2013, and then uninstall Exchange 2010 from DC1 as recommended by Microsoft.

All servers are behind the same firewall, using private IPs, and facing the Internet using the same public IP. Ports 25 and 443 are forwarded to DC1.

Now Exchange emails on mobile phones are working well. Also webmail works well when we try to access https://domain.com/owa.

When I change port forwarding of 443 to DC2, then mobile client for exchange stops working and webmail gives Exchange 2013 style error message: 

:-(
something went wrong

Sorry, we can't get that information right now. Please try again later. If the problem continues, contact your helpdesk

Migrate sendmail aliases to Exchange

September 29, 2015, 1:44 pm

Good afternoon, all!

I'm working hard on a migration from Sendmail/Dovecot to Exchange 2013 CU9.  I have the current aliases file from the sendmail server showing mail redirects to a user or users.  Most of these are alternate ways to send system alarms.  For instance, an alarm can be sent SMTP, SMS, and to the user's outside mail account.  That way if one messaging channel is down, critical notifications and alarms can still get out to employees and administrators.

Several users have multiple addresses to forward messages to - SMS, text, outside Gmail accounts, and so forth.  AFAIK, I'll need to set up a mail contact for each user with that particular messaging channel. That is, for user1@test.com, I'll need to set up a differentiated contact for their SMS line, one for their outside mail account, one for their pager, and so forth.  I haven't seen where I can add all these to a user mailbox and specify which message channel to use for any one group.

Am I correct in this or am I overlooking some other way to apply and manage multiple message channels?

Thanks to all for looking!

Migration from Groupwise to test domain

September 29, 2015, 10:56 am

Hi,

When we did our migration from Groupwise to Exchange 2013 we initially started with a testing domain (ad.domain.com) to start migrating to.  After some accounts were migrated to this test domain and we did some other testing, we changed the accepted domain from our test to our production domain (domain.com).  A few days later we noticed some issues with some users sending email to other internal users and it appeared they were sending to the test domain which was being bounced back as its no longer an accepted domain. We do not want it to be an accepted domain as it was only for testing.  We then noticed every user had 2 SMTP addresses listed so we removed the one that had the testing domain and left the correct one.

Our primary issue now is that users RecipientCache for the OWA is constantly populating itself with these invalid addresses as it must be scanning emails in their mailbox that have the bad domain used.  We can use a script to clear the bad domain from the recipientcache but its only a temporary solution. There does not appear to be an issue when using the Outlook client just in the OWA.

We were able to verify that the emails that were migrated from groupwise before either the SMTP change or the accepted domain change all appear to have the testing domain and the correct domain on the users listed in the messages.

Also to make things more confusing  the testing domain that we used was the same as our actual AD domain that Exchange is connected to (ad.domain.com).

We are using Exchange 2013 CU9 on Windows Server 2012 R2

Thanks in advance,

Matt

Upgrade from 2007 to 2013

I have an Exchange 2007 environment (Edge - Hub/CAS) that I will upgrade to Exchange 2013 in the near future (on-premises). I am using the Exchange Server Deployment Assistant (https://technet.microsoft.com/en-us/exdeploy2013/Checklist?state=2419-W-AAAAAAAAQAAAAAEAAAAAAAA%7e) and checking out the various steps in the checklist. Presently, my MX record points to a cloud-based spam filter (MXGuarddog) which forwards all non-spam email to my edge server.

How will this affect the mail flow during the transition steps mentioned in the checklist, mainly the existence of legacy and new servers?

Thanks for the input!

Hi

Our exchange server certificate will expire in few days.

I tried to renew the existing certificate so i clicked the renew and exported the csr, but when i logged in to Entrust portal and used the csr they told me that from date 11/1/2015 they wont be able to issue certificates including local names.

now my question is what happens if somebody wants to use the certificate for internal use only and not using it on the internet?!

what shall i do in that case?

do i have to create dns records for my local server names publicly?!?

Thanks in advanced

Exchange Admin Centre The user name or password you entered is not correct.

Hi

We have in place an SBS 2011 server and have now added a Windows 2012R2 server and installed Exchange Server 2013 standard as per the Exchange Server Deployment Assistant.

The installation appeared ok until I tried to login to the EAC with the ?ExchClientVer=15 using the same account used for the installation. This account has the Organisation role.

When I try to login, I have tried all ways including adding .local, removing.local etc, but each time I get the user name or password you entered is not correct.

I have checked the iis management Exchange Back End and have enabled Windows Authentication.

Also when I go to the exchange shell I get an access denied error.

The SBS 2011 exchange runs without issue.

Any suggestions where this is going wrong?

Many thanks.

Hello,

i am doing a mailbox move of 140 GB from exchange 2007 (sbs2008) to exchange 2013.

This move is very slow (20 GB is 5,5 Hours).

I can see high cpu-usage on the sbs2008-server for store.exe (between 80-100 %).

What can i do to speed up this process for now and in future migrations like this?

Hi everyone,

I've successfully installed multiple Mailbox and CAS 2013 SP1 servers into an existing Exchange 2010 environment.

However, when I get to the Edge Transport role on a separate server, at step 7 of 9, it throws the following error:

Error:

The following error was generated when "$error.Clear();
	new-ExchangeServer" was run: "Value cannot be null.
Parameter name: Cannot get child of ADObjectId:	this is a GUID based ADObjectId.".

Any ideas what could be causing this? I haven't been able to find anything of significance while searching around...

Migrating PF (ex2010->ex2013)

September 30, 2015, 12:05 am

Hi there.

In the phase where we had moved all the users from ex2010 to ex2013 and also arbitration mailboxes. The last step is that we wish to move PF to modern PF.

QUESTION1 : PF DATABASE SIZE

PF database size on exchange 2010 is 30GB. Now the thing is we have done a lot of DELETING on PF, but the database on exchange2010 is still the same size (30GB). How do you permanently delete those deleted items in PF?

QUESTION 2: LEGACY PUBLIC FOLDER

Next thing. We have enabled legacy public folder durring the coexistence ex2010/ex2013.

https://technet.microsoft.com/en-us/library/dn690134(v=exchg.150).aspx

Well we have found out it doesn't really matter if you put Publicfolderenabled remote or local  (Set-OrganizationConfig -PublicFoldersEnabled Remote, Set-OrganizationConfig -PublicFoldersEnabled Local), because migrated users from ex2010 to ex2013 didn't have problem accessing PF on ex2010. The only problem was when you have created new user on ex2013. That user was not able to Access pf on 2010, but that's ok, because we don't have any new users.

Soo currently the setting is set on this "Set-OrganizationConfig -PublicFoldersEnabled Local".
Can we leave it that way, and continue with PF migration to MODERN PF? Or do we need to do sth else regarding enable/disable legacy public folder before the migration of PF'S? with best regards

Is it wise to enable index on DB durring workin hours?

September 30, 2015, 4:04 am

Durring the migration of mailboxes between EX2010 -> EX2013, we have created 28 DB's on Exchange 2013 and turn off indexing on them because we wanted to have a faster migration. Now we have moved all the mailboxes from 2010 to 2013, only public folders are left to migrate.
We are considering to enabled indexing back on those 28 DB's where 200 mailboxes are.

If we enabled it all at once, Will it "kill" Exchange2013's performance?

One more question. Would it be better that we first do full backup of "non-index" DB's (to get a rid of transaction logs first), and after that enable indexing? Or it doesn't really mathhers when?

with best regards

One question regarding the migration process from legacy public folder (EX2010) to modern public folders (ex2013).

Modern public folders are now on "mailbox base". If client is using Outlook 2013 with "Use Cached Exchange mode " does this means he Will download the hole content of public folders locally to his pc?
