The problem with the file

[cornea]

Which is the best tool to convert Offline Storage Table (OST) file into Outlook (PST)?

I may be wrong, but I think you can just create a PST file in Outlook and then copy/paste the contents of the open OST into the PST.

Cornea, does the OST belong to a different user?
