Strange one here. Two of my domain admins get the red x when attempting to send email from their Blackberries. I have to continually go back and grant 'Send As' permissions to the BESAdmin account to allow them to send. I am also a domain admin but do not have the problem and nor does the BESAdmin account have 'Send As' permissions on my account. Anyone have any clue what's going on here?
Thanks

A BES user should NOT be a Domain Admin. This is well documented by RIM.
(Your account will eventually fail as well, so just consider yourself lucky for now.)
You should remove Domain Admin privileges from all BES users.

See here:
KB04707 - Unable to send email messages because Send As permission has been revoked - Port3101.org : Your BES Connection

and here:
AdminSDHolder - or where did my permissions go? - Port3101.org : Your BES Connection

Thanks peguin. I appreciate that and was aware of the recommendation but I'm getting slack from them for possibly having to reconfigure their mailboxes to be associated with a non-domain admin account. I've gone days now without having a problem - and BESAdmin does not even have send as permissions listed on the security for my account. I'm in the exact same protected groups as they are - what's the deal?

If you want your BES and handhelds to work correctly for everyone, all of the time, then you need to follow RIM's guidelines and best practices.

It's called the Principle of Least Privilege... and you're not following it.
Principle of least privilege - Wikipedia, the free encyclopedia

Make yourselves normal users, and then create a secondary login with Domain Admin privileges. Only use that secondary login when necessary.

I realize I am not following guidelines and best practices. I'm telling you, BESAdmin does NOT HAVE 'send as' privileges on my account yet I'm in the same exact protected groups as those with the problem. I mostly would like to understand what might be different about my account. Is it something with when I've Enterprise Activated, or reloaded my own account?
Anyone?

did you ever modify the adminsdholder object?

No, and I may not have been clear about the issue. I'm a domain admin just as those who cannot send. The BESAdmin account is not listed as having 'Send As' permissions on my account, yet I have no problem sending. I'm curious as to what might be different about my account. I've read I can modify the adminsdholder object, but wasn't sure if I wanted to go that route. Again, what might be different about my acccount that I don't have a problem? Thanks for your help.

It might be a random issue for you on why you can send. I have seen it before.

penguin3107 and hdawg did give you a solution to your problem.

I KNOW they gave me a solution. I'm not doubting that, I'm just looking for someone who can give a solid answer on this 'random issue' - jeesh!

I wish you luck in your findings.

You've got some issue with active directory ... look there.
