At the moment, I couldn't understand what should I do and approached OST recovery experts. They suggested me OST to PST software to resolve the issue.

Though, I already had installed anti-virus on my system, but I had no idea how did virus attack to Exchange OST files? It made the files completely inaccessible and left me annoyed. For the moment, I tried scanost.ext to repair OST file, but OST files got too damaged to repair by free utility. Then, I inched towards third party tools and got OST to PST converter. It deeply scanned OST files to remove the corruption thus making it virus free completely.

I could not stop myself to review OST to PST software because it worked beyond my expectations. My OST file got inaccessible due to oversize issue. I tried to remove stuff from oversized OST file, but it didn't work out. With the help of OST to PST recovery software, I first converted inaccessible OST to PST and then performed split operation over the converted PST file. Eventually, I could access OST file and corresponding emails.

I was literally shocked to see the way this software performed all the required tasks of OST file recovery in a few minutes and that too, with full accuracy. The software was running in the background, and thus I was able to browse websites on the Internet and look at my emails without any difficulty.
