Using Classic Outlook on Windows for personal email, calendar, and contact management
Please fix this. I have several email accounts in my Outlook, and my OST file is 50 GB, I've been switching between New Outlook and Old Outlook only to test and see if this issue is resolved or not, and to my great dismay now I cannot use the old Outlook anymore, because the New Outlook did something to my OST file so it only works with the new Outlook. Whenever I try to use Old Outlook, it freezes up and sync is disabled.
