I have a client that has a disclaimer or signature that continues to show up on all replies that he sends. There is no signature in his Outlook profile. There are no transport rules that are adding a signature or disclaimer. There are no Group Policies that are adding any signatures or disclaimers. The TMG gateway is not adding a disclaimer or signature.  It happens in Outlook, OWA, and on his mobile device.  So this is happening somewhere in Exchange or the TMG.

I did find that there was an old Transport rule that at one time did add this signature and disclaimer, but it has been disabled for a long time.  I changed the rule and re-applied it but it made no difference.

Is there a way to remove this attribute or to determine where it is being added as the reply is sent?

Hi,

According to your description, I understand that a transport rule remain effect even though it has been disabled.
If I misunderstand your concern, please do not hesitate to let me know.

Does this issue only occur on this account or all users? How about re-configure Outlook profile with new PC client for testing?

If it works fine in new client, it might be caused by a hidden inbox rule. Please use MFCMapi to deleted it. For your reference: http://blogs.msdn.com/b/hkong/archive/2015/02/27/how-to-delete-corrupted-hidden-inbox-rules-from-a-mailbox-using-mfcmapi.aspx

If the issue persists, please try run message tracking log to trace problematic message to know details about deliver process. It's more helpful for further troubleshooting.
Note: try disable all transport rule, then test.

Thanks
