If Your Account is Blocked

Microsoft's Office 365 includes Forefront Online Protection for Exchange (FOPE). FOPE blocks accounts that appear to be sending malicious messages or apparent spam.

If your account gets blocked by FOPE, you must follow the steps outlined below.

There are two ways you may find out your account has been blocked. ITS  may contact you.  Or, when you try to send a message, you receive this error message:

Delivery has failed to these recipients or groups:  Your message con't be delivered because you weren't recognized as a valid sender. Make sure your sending address is set up correctly and try to send th emessage again. If the problem continues, please contact your helpdexk. The following organization rejected your message: Diagnostic information for administrators: Generating server: #550 5.1.8 Access Denied, bad sender ** Original Message headers: Received: from ( by ( with Microsoft SMTP Server (TLS) id 15.0.898.11; Tue, 18 Mar 2014 15:10:26 +0000 Received: from ([]) by ([]) with mapi id 15.00.0898.005; Tue, 18 Mar 2014 15:10:25 +0000 From: First Last To: Recipient Name <>

Here are the steps you MUST take to restore your account

  1. Contact ITS Support at 670-3000.  
  2. Change your Active Directory (WUAD) password immediately.
  3. ITS  may need to run diagnostics on your computer(s) to determine the cause of your account's bad behavior or gather other information about how your Office 365 account may have been compromised.
  4. After the password has been changed and computers/devices checked and fixed (if needed) then ITS will contact Microsoft and ask to have your account re-enabled.
Microsoft will evaluate your account's activity and re-enable the account, provided they find no outstanding issues. The timing for this part of the process is out of Washburn's control; it make take a few hours or a few days.
