An OST file is NOT as PST file and cannot be used as one.

Why do you have an OST file? Are you on Exchange?  If so, delete the OST file (back it off to a non-Outlook location), log into Exchange (make a new profile / account) and allow the OST to rebuild by itself.

OST is just a cache file, so the above approach works.

Hi John,

that is what I have done: new profile and let it rebuild the OST from scratch: still, same error.

Try this on a different computer and see if you get the same error. The Exchange mail file could be damaged
