Using Classic Outlook on Windows for personal email, calendar, and contact management
Greetings!
This is Tin, sorry to hear that you're unable to open your Outlook app. I'll do my best to help. May I know if you have tried to reinstall the app already? Are you getting any error message?
First thing to do is to restart your computer and check if the issue persists.
May I know if the issue is only happening on Outlook app?
Will wait for your response.
Thanks,
Tin
