Can't convert OST => PST

Hello everyone, I’m new to this forum. I’m posting this message because I can’t convert my OST files to PST files using the solution at Convert OST. Free OST converter. The site displays the message ‘Unexpected error’. Thank you very much for your help!

Hello @lseg,

Thank you for your message.

The “Unexpected error” message on the OST to PST conversion page may be related either to a corrupted OST file or some internal limitations.

To help us investigate the issue, could you please clarify the following:

  • Size of your OST file
  • Steps to reproduce the problem
  • At which exact stage does the error occur

It would also be very helpful if you could share a sample of the problematic file that triggers the error.
