You can't access a mailbox after you're migrated to Office 365 dedicated/ITAR (vNext)
Users can't access their mailboxes after they're migrated to Microsoft Office 365 dedicated/ITAR (vNext).
This issue occurs because the data in old profiles prevents Outlook from connecting or because users are using an early version of Microsoft Outlook 2013.
To fix this issue, follow these steps:
- Run a repair of Office.
- Create a new profile (in addition to the original profile that can’t connect).
Please also collect an OffCat log of the affected Outlook profile to provide together with the Outlook logging. You may submit a support incident online to Microsoft Online Services Support. Or, you can contact Microsoft Online Services Support by telephone.
There is a known access issue in early versions of Outlook 2013.
