I was advised to post here from Office 365.
I am trying to migrate a SBS 2008 server to office 365 for mail.
The mail currently works fine from the onsite exchange server and for users working remotely.
When I try to do the cut over migration I get an error saying it cant connect to the exchange server and I should try the outlook connectivity tester to make sure its working fine.
Once I specify the server and username and password it all connects fine apart from the SSL certificate with the error:
The certificate chain couldn't be built. You may be missing required intermediate certificates.
From what I can understand this is down to it being self signed from the sbs server. But the connecting to the server still comes back as its fine so it should work on the 365 migration page?
What am I doing wrong for this not to work?
On another side note.. As they have a lot of mailboxes I wanted to do a Staged-Migration to only upload the mailboxes I want. I then want to decommission the onsite exchange server and just use 365 for user accounts and passwords. How would you go about switching to this? / Would it be a better option?
