Mail.app import from Entourage failed I am trying to import my entire folder structure from Entourage 2008 to Mail on a Mac running OS X 10.5.8.

First I tried to export the whole email database from Entourage to the Desktop as a .rge file. The export aborted with a message saying that my Entourage database is corrupt and that I should rebuild it.

I then went over to Mac Mail and imported the Entourage folder structure through File > Import mailboxes… > Entourage. The bulky import did take some time and the progress bar never reached its full length, but at the end the import said it was successful.

When I checked the imported folder structure in Mail I noticed that quite a few subfolders were missing. I checked Console and saw following message:

Mail[2899] Applescript Error: 
  aliasForMailImporter got an error: 
  AppleEvent handler failed.


What does that mean and what can I do to move my subfolder structure over completely?
Based on the message saying that your Entourage database is corrupt and needs to be rebuilt, I have to guess that your Entourage database is corrupt and recommend that you rebuild it.

As the saying goes, "Garbage in, garbage out."

Here are the directions on how to rebuild your Entourage database.
