Using Classic Outlook on Windows for personal email, calendar, and contact management
I have to put my vast amounts of archive email in .pst as it you let the main folder get too big the whole thing corrupts.
You can also back up data easily and share it with others eg. when you leave a job and hand records to your successor
But I just got a pop up asking me to to move to new outlook and saying I would not be able to access .pst. That is the archive of my life and and my work for a decade
What's going on?
