I'm in the final stages of testing a staged migration from Exchange 2007 to Online Exchange - I've synced and migrated a test user, and have verified that the user is now a MEU.
However, in Outlook on this test users computer it appears that I have to create a new profile at this point..
(If I create a new profile for the user, it works great, and the relay between exchange on-prem and 365 is working as expected)
BUT, do I need to create another new profile again once I change the MX Records to direct straight to 365? So that I have now created 2 new profiles for my users? I thought the point of staged migration was that the user continues to use their profile seamlessly, and it's only once the MX records are changed, that the user needs the new profile?
