Using Classic Outlook on Windows for personal email, calendar, and contact management
I think it is important that the specific issue be the topic of the thread, though as someone else said with two years of posting and no resolution I wouldn't be holding my breath on a solution.
If multiple issues are combined then the original poster's query is diluted and it risks a separate issue being fixed and the thread being marked as resolved without fixing the original problem. There is a separate thread for the multiple email accounts issue.
