When try and "send as" receive NDR "the following user cannot be reached error"

Not sure what's going on...
Exchange 2003
AD 2003

Was able to do this a week ago...

Now whenever we assign the "send as" permission for a user or distro group - when we try and actually "send as" we get an NDR stating that the user could not be reached....

any ideas

btw - works if you are a domain admin...

Hi,

I was monitoring this question but didn't post any comments as I hadn't a clue how to help.

Could you explain a little further which perm you changed. I'm interested in your fix.

Thanks.

yep -

I totally forgot that Exchange Admins are by default denied access to "send as" another user or group.  In order to override this default perm, you need to right click into the properties of the information store, select the security tab, select the user you wish to assign the "send as" perm to, click advanced, find the deny statements and change to "allow"

Hope this helps!

thanks.

So:

In Exchange 2003 Domain admins can 'Send as' by default but Exchange Admin can't.

But why did it suddenly stop working?
