Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear De Paul N. Kwizera MSFT,
Below is the PowerShell error
And below is the error on the Exchange Admin portal
The account was migrated to Exchange Online and had an on-premise archive enabled before migration.
After a long back and forth with Microsoft support, I was able to resolve the issue using the following procedure.
- Disable the Archive on the on-premise Exchange admin
- Did AD Sync.
- Removed Office license on https://admin.microsoft.com/
- Did AD Sync again
- Enabled Archiving on Exchange Online
- Started Managed Folder Assistant: Start-ManagedFolderAssistant -Identity <email>
- Archiving was restarted.
