How can I limit message sizes in Exchange?

A. Maximum size limits can be set on the Message Transfer Agent (MTA) for inter server traffic by selecting the General tab of the MTA configuration dialog of the server. The message would then be returned to sender in the event of the message being to large however for the people on the same server this limit is not used.

Limits can also be set on a per user basis for all traffic:

  1. Start the Exchange Administrator Program
  2. Expand the Organisation and select the Recipients branch
  3. Select the user and select Properties from the File menu
  4. Select the Limits tab
  5. Its then possible to set outgoing and incoming maximum message sizes
  6. Click Apply then OK
