Outlook migration from 2011 to 2016
Trying to upgrade from Outlook 2011 to 2016. Getting the error "you don't have sufficient permissions" error (attached). Have found mention of this error on Microsoft's support site, which give a couple of specific suggestions, but neither did the trick. Will outline the failed solutions below. Is there another approach to try?
Suggestion 1: manually fix the permissions on that 2011 database. Same problem afterward.
Suggestion 2: rebuild the profile. Didn't help
Unfortunately for this person, switching to Apple Mail is not an option.
No it's Mojave, but you might be onto something with allowing "full disk access". Was aware of the locations of the mail databases and have "opened up" permissions on that Microsoft User Data folder in Documents.
Turned out that the "insufficient permissions" error message was a red herring. The problem was the Outlook/Microsoft sync service process kept being restarted in the background, even after quitting it. Once I figured out there was a launchagent that lived inside the ~/Library/Launch Agents folder (called com.microsoft.LaunchAgent.SyncServicesAgent.plist), deleted it and restarted the Mac, the import went as expected.
