The program you suggested not only converts OST to PST format, but also removes the password from PST files. I think you should know that. Thanks for these great tips! I started with the manual method, but since I need to convert multiple OST files, I switched to the automatic method.

I recently had an issue with my Outlook, and I was so relieved to find a repair software that could help me out. The Repair Toolbox for Outlook software that you have describer was a lifesaver! It was easy to install and the instructions were straightforward. The repair process was quick and efficient, and it solved my problem in no time. I’m so glad I found this repair software, it saved me a lot of time and hassle. Highly recommend it for anyone having Outlook issues!
