Hello everyone
I have installed Exchange 2013 in 2010 environment that have 2500 users. Configured everything and migrated 4 users for test without an issue.
Internally and Externally everything working perfectly including Autodiscover, redirection..etc however on Outlook 2010/2013 clients users either on 2010 or 2013 keep getting Certificate warning with local FQDN of the Second exchange 2013 CAS is not included in the Public wildcard certificate which is associated with the IIS,SMTP services on both CAS 1 and 2 for exchange 2013.
The interesting thing is that the mail, autodiscover is configured on local dns to point to first CAS01 but the certificate error message is coming from the second one CAS02.. I don't know how.
Regardless of the Error Outlook clients connect without any issue but still it's very annoying for the customer.
When I delete and recreate a new profile. Users don't get the warning anymore.
I have 2 CAS and 2 Mailboxes on Exchange 2013. 1 CAS,HT and 1 Mailbox server on Exchange 2010. Their Local DC is not compliant name space with the external domain.
Local DC is domain.local.
I have setup and configured all the Internal Webservices on CAS1,2 on Exchange 2013 to match the External one in order for the server not to require local FQDN.
Is there any way to get rid of this error without deleting and re-creating all the users's profiles ??
I would appreciate your comments.
Thanks
Mohammed JH
