Outlook 2007 crashes when hitting Reply, or Composing a New Message (PDFMOutlook.dll)

outlooklogoWhen googling for this problem, it seemed to be a very well-known unresolved problem, but oh well, maybe it’s valuable for somebody:

When trying to reply a message in Outlook 2007, my Outlook crashed, every time, no exceptions. I had to restart Outlook everytime, and after that everything went OK. I figured out that PDFMOutlook.dll was causing this problem. I still have Adobe 6, so I didn’t except there to be an update, and actually I didn’t use the plugin anyway, so here is my solution:

Delete PDFMoutlook.dll, or rename it :)

You can find the file in C:\Program Files\Adobe\Adobe Acrobat 6.0\PDFMaker\Mail\Outlook\PDFMOutlook.dll

If you want to do it the clean way, you can also use regsvr to unregister the dll. In that case, hit the following path in your Run-box:

regsvr32 /u “C:\Program Files\Adobe\Adobe Acrobat 6.0\PDFMaker\Mail\Outlook\PDFMOutlook.dll”
(of course, if you have version 7 or 8, or you installed Adobe into another directory, please rename the above path to the correct path)

  1. I forgot to mention, I disabled the addin in Outlook. The true solution is probably an uninstall and a reinstall of Acrobat.

  2. This fix worked for me. You can probably just delete the dll since Outlook’s call for the dll installs a new copy of the file.
