Using classic Outlook for Windows in business environments
I get what you mean, to individually set a given account to be the "primary account". I'm using the client edition of Office Home and Professional 2024. This works well if you only have two accounts. Unfortunately I have six accounts to reorder. I thought I could rotate through each targeted account in reverse order, making each one "primary account" one-by-one, but unfortunately this approach only works with the account currently designated as "primary account". As soon as you move on to the next account the previous account resumes its original order, instead of just moving down one.
Why on earth re-ordering accounts by either drag-and-drop or a move-up/move-down option from the more options button, just like the Favorites folders is beyond me. Microsoft just dumbs it down and removes functionality with this client version. They seem to have always struggled to make things both user intuitive and fully featured in one-go.
