One reported problem is a corrupt Outlook “extend.dat” file. You can then go back and start re-enabling the add-ins one by one until you find the one that’s causing problems.


This is all that you need most of the time. The previewer gives a faithful view of the email message without opening it. The simplest solution is to use FileCenter’s Professional’s “Preview” button instead of opening the MSG file. Any number of things could be causing the problem. Normally Outlook should release the message as soon as you close it. This only happens if Outlook is running, and it goes away if you close Outlook. The file may not exist, you may not have permission to open it, or it may be open in another program. It’s possible the file is already open, or you don’t have permission to open it …Ĭan’t open file. When you try to re-open the MSG file, you get an error message that says, in part: If you open then close the file, you can’t re-open it, rename it, or delete it in FileCenter. You’ve saved an Outlook email as an MSG file.
