When Outlook 2011 crashes with the following error message when you are trying import a .pst file into it

Outlook has encountered a problem and needs to close

verify that you have the latest Office for Mac updates installed as well as Office for Mac Service Pack 1.

The latest updates latest Office for Mac update has some fixes that address an issue with importing .pst files.

You should always import a .pst file into a new, empty Outlook 2011 Identity. This way, if there is a problem it will not affect the data in your working Identity.

After you import into the new Identity, you can export under File > Export as .olm file. This can be imported safely into your Identity.

    Microsoft tech support, Internet, Systool DBX to PST converter. If I use Windows Mail, will it import my .wab (address book) all DBX files? How do I export Windows Mail ( account?) to Outlook 2013 (import)? Is there another 3rd party tool to do it?
    How about importing to Outlook 2003, using that pst to import into OL 2013? Thanks

    MS Outlook files in Office for Mac 2011 is problematic! I imported my pst's into Office for Mac 2011 along with backups of those pst's, and backups of those backup pst's. I want to merge all these emails and delete the dups, but I can find no way to do so. Does anyone have any ideas?

      You need to import each one in outlook, then you need to use a duplicate finder utility - but I'm not sure if there are any for the mac.
