Is there an attachment file size limitation?

There is a per e-mail limit of 25 megabytes. Each e-mail cannot exceed a total of 25 MB including the header, body and all attachments. (This limit was updated 6-20-2011.)

  • If a message is stopped from receipt in Outlook because it is larger than our send/receive size limit of 25MB, it is held for 7 days in the RHS user's Forefront Online Protection account (this is your Microsoft online SPAM filter).
  • The below Instructions explain how to retrieve those attachments from Forefront.
    • If you are sent a message that is larger than the RHS send/receive limitation, you will receive an e-mail similar to that shown below:

  • However, you may still retrieve the information and attachment contained in this message by logging into your Forefront Online Protection account.
    • Type quarantine.messaging.microsoft.com into the address bar of your internet browser or use the link under Favorites in Internet Explorer. It is within the RHS folder in your favorites.
  • The password for Forefront is not the same as the Microsoft password that you use to login to your RHS computer.
  • You will have to set it the first time, by clicking the "Need Your Password" Link and following the directions that are e-mailed to you.
  • Your user name is yournetid@rhs.msu.edu
  • Once your password has been set, login to your Forefront account and you will see a screen similar to that below: 

  • Click on POLICY E-MAIL on the left hand side of the screen
  • This will show you a listing of any messages from the last 7 days that exceeded the Outlook send/receive limit:

  • If you left click on the subject of the message the content of the message will open:

  • From here you can LEFT CLICK on the attachment and CHOOSE TO SAVE THE FILE from the window that pops up.
  • Choose the location (share or home drive) to save to and click OK.
  • You can now go to the location you saved the attachment and open it to view.
