“My Outlook used to freeze frequently whenever I work or access emails from it. I have heard that it is a result of increase in PST file size. So I have decided to compact Outlook PST file to reduce its file size. But I am not able to access emails from my Outlook since the day I have compacted it. I get an error message that “The messaging interface has returned an unknown error”. I don’t know how to get rid of this error. Anyone has suggestions that could help me to get out of the problem”

  • Press the "Compact Now" button
  • Click "OK" when done
  • Errors have been detected in Outlook.PST file. Quit all mail-enabled applications and run Inbox Repair Tool

But as said before you should be careful while compacting PST file. In case the size of the PST file is very large, then it may take some time and you should wait till the compaction process gets completed.
