I'm in the middle of migrating to Exchange 2010 after finally getting everything in the event log cleared up

I migrated one users mailbox, and of course, there is an issue.

Any time the user sends HTML emails, they are stripped and the recipient receives a blank email (inside and outside organization, tested multiple accounts it isn't a client issue).

After investigation, the user has no send as permissions after the migration to Exchange 2010 (not even NT AUTHORITY\SELF). When trying to add this I get the following error and I don't know if it has anything to do with it:

> 
> operation failed on win2k8dc1.domain.local this error is not retriable. access is denied active directory response 00000005. insuff\_access\_rights, data 0
> 
> 
> the user has insufficient access rights.
> 
> 
> 

I also disabled all transport rules and anti virus email filtering (has been disabled on server, disabled it on users pc as well).

The user is using outlook 2007.
