Work for a company that uses IMAP email system. Had a guy who's profile was all sorts of glitchy. so I did what I used to do 10 years ago when I was the unofficial IT guy (guy with one eye in the land of the blind) And setup a new profile for him. DID not realize that a couple upgrades ago, that they switched everything to OST files, and that OST files, cannot be transferred or renamed like they did with PST Files. SOOOO I've lost all this guys contacts. https://www.msoutlook.info/question/do-not-risk-losing-your-contacts-and-calendar-when-using-imap This link says, convert it to a PST file. But the software to do that costs 100 bucks... any of you guys messed with this before? Have any suggestions?
