Entourage - Error 17099

[vsengp]

I applied 12.1.15 update to Entourage 2008. I can send emails but can't retrieve them. It gave me a error 17099 - invalid email. I double checked the setting with Entourage X and they are identical. Why does it work on X version and not with 2008?

Lots of threads on macosx.com on this issue, at least as it relates to your error message:

But I haven't seen it occur when trying to retrieve email, only sending. Let me know if the first and/or second threads on this url help you.
