Using Classic Outlook on Windows for personal email, calendar, and contact management
@Peter L said
I was having problems with my computer a few days ago when the Microsoft staff member ended the Chat without notice.
I am sorry that Microsoft Support left you in the lurch. But I am afraid your only choice is probably more Chat.
If you have a Qualified MS 365 Subscription you may be able to get Call Back Support.

If not, then Chat is your only option. From inside your Classic Outlook that would be the menu choices: Help -> Contact Support. You do not have any control over what Support agent you get, I hope you get a good one next time.
I am willing to try and work on your problems using this forum. But the conversation will be painfully slow, and since I can't access your PC, you would have to describe the results of each change to me via messages. Please advise if you want to try this route.
