Migration assistant choked on this folder twice, leaving me unable to move it via a thunderbolt to thunderbolt connection. This folder needs to be copied from Mac to Mac when migrating data.
The new location is not well documented, and I stumbled upon it on an obscure forum post, the location is ~/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/Main Profile In Outlook 2016 for Mac, Microsoft in its infinite wisdom, has changed the default location of the email profile folder. I wanted to share my info in the event that it helps someone out there. I recently had to help a client move from one Mac to another, during the process one task proved more challenging than originally anticipated.
