I am migrating from SBS 2008/Exchange 2007 to Office 365.
I have chosen to upload .pst files for my mailboxes (i only have 10). I am using one very small mailbox as a test to get started.
My problem is that after I have imported the PST file, the contents of the user's mailbox are empty. No mail seems to have been copied.
I created the PST files using a 32bit Outlook 2007 client with Exchange PowerShell Export-Mailbox cmdlet. and followed the instructions here:
Everything worked perfectly. I had created a new user in office 365 prior to uploading the pst file and given that user an Exchange Only license. I mapped the PST file to the user I had previously created. That seemed to be successful.
When I look at the mailbox usage for this user in Exchange Admin | recipients | mailbox users I see that the a small amount of the 50GB has indeed been used. However, when I log in - separately, on another computer - to outlook no messages have been copied. There are no filters set on outlook.
So it looks like the mapping is working correctly, because some of the mailbox space is definitely being used. But the messages are not visible.
Can any one tell me what I might be doing wrong?
By the way - when i set up Exchange in the first place, i added my domain names, but I didn't move the DNS records to point to Office 365. I want to move all the mail here first, then redelegate the DNS record as the last thing. So my users are set up as email@example.com, but mydomain.com does not actually point here as yet. I did use mydomain.com in the mapping file, rather that the mydomain.onmicrosoft.com that office assigned to me. Could that be part of the problem? I'm assuming not, as the mailbox space has been used. But i thought it worth mentioning.
Thanks in advance!
