I have a user that creates and e-mail and type the e-mail address for the recipient and when he clicks send a the e-mail goes to a different person. I have scanned for viruses, malware, and any other malicious program. I have searched many sites and have not found anyone that has experienced this anywhere.
I have run scanpst to fix any errors that may be there and it fixed a few. The data file is 4GB in size.
The user is using Outlook 2010 and a sbcglobal.net e-mail pop account so there is no exchange involved.
My plan is to create a new PST file and see if this resolves the issue. If anyone has any other ideas I would love to hear them
