Hi pbarham,
If you have access to the CRM database, it be can fixed rather quickly.
In dbo.ActivityPointerBase
Email Activity has ActivityTypeCode of 4202, with the following StatusCode:
3 = Sent
5 = Canceled
6 = Pending Send
So, you can select all email activity records with statuscode=6 and confirm that these are the records you want to change first
SELECT * FROM dbo.ActivityPointerBase WHERE ActivityTypeCode=4202 AND StatusCode=6
Then, update all email activity records with statuscode=6 to either statuscode=3 or 5
UPDATE dbo.ActivityPointerBase SET StatusCode=3 WHERE ActivityTypeCode=4202 AND StatusCode=6
CRM service will not try to send these pending e-mails then, because they are now either in canceled or sent state.
Hope this helps,
Danny
