I've got the same problem after an "Update" last week for 2003 SP2 -- sure
could use some help.

I am having the same problem although I get a system email that says:
This message could not be sent. Try sending the message again later, or
contact your network administrator. You do not have sufficient permission to
perform this operation on this object. See the folder contact or your system
administrator. Error is [0x80070005-0x80070005-0x000508].
I have reinstalled and run Office Diagnostics but still no change.
