Using classic Outlook for Windows in business environments
Don,
I shared your feedback in the bug tracking this issue. The original guidance said that the folders would be removed on the next sync but clearly that is not the case for you. If you get the opportunity, could you please try removing the account from Windows Mail and add it back and see if that forces the sync to clear it. I'll post back any updates I get.
Gabriel,
Removed the "inffected" .hotmail account and re-booted PC but the folders are still there after reinstating the account.
The folders also still appear in my outlook.com.
Edit
After an hour or so "playing" I have managed to delete these folders and have all my emails now in 1 box.
So far after closing and reopening windows mail the folders have not reappeared
Will see what tomorrow brings after overnight shutdown.
All good this AM, many thanks Gabriel
