[quote:cdb7f14e5f][b:cdb7f14e5f]5.1.3 error in Entourage, and how to work around it[/b:cdb7f14e5f]
If you're using Entourage 2008, you might have noticed that some of your contact groups may not be working anymore. When trying to send to a group of recipients, you might get a 5.1.3 error.
Whenever I got that error, I’d open the group from within the email to see the bad address, and there was always a blank recipient at the end of the list. The remove button is grayed out so I can’t remove the blank line, but if I select the blank recipient, and then select the last recipient, the blank line disappears, and sometimes I can send the message.
When I still can’t send the message, I found that the “sort list” button removes the blank entry, and I can send a mail using that list.[/quote:cdb7f14e5f]
