Good morning! We're in the midst of migrating user mailboxes from Exchange 2010 SP3 to Exchange 2013 CU3.
I've done some research on this topic and discovered that for what ever reason in the EAC that the 2013 MBD didn't have an assigned Default Offline Address List assigned under Client Settings. Corrected this issue.
When running Get-Mailbox billg | fl Name, OfflineAddressBook,Database against a migrated mailbox I get the following output (Note the OfflineAddressBook: is blank:
Name : Bill Gardner
OfflineAddressBook :
Database : Mailbox Database 1028547986
From the Outlook 2010 and 2013 clients we are recieving the following error:
Task usera reported error (0x80190194) : 'The operation failed.'
The Exchange server migration state is:
There are still a few User Mailboxes that need to be migrated off of 2010.
Public Folders have yet to be migrated from 2010 to 2013.
Any guidance will be much appreciated.
Regards, Bill
