I agree that this email account rearrangement process should not take so long, or any length of time, to get corrected. I did go through the only valid gyration which ended up not working correctly. I did the new Outlook "Settings> Accounts> Manage> set the account you want to be on top as primary. Outlook will restart, and your account will be at the top. That's the only way to move it around" steps. Then the #1 email account name switched to to a #2 location and vice-versa.
HOWEVER, the #1 Inbox stayed right where it had been, and the Sent file and the Drafts file also stayed right where they had been. Maybe it's just a Favorites thing, but the loose ends need not exist.
What a lot of ****.
