Has anyone set different Delivery Restriction based on a Windows 2000 OU? I work in the banking industry and our branches are connected with either 384K or T-1 lines and we have problems with users attempt to read messages with large attachments 10-20MB. Our Exchange 2000 servers are centralized in 2 different locations. Branch employee's Windows 2000 accounts are organized by location or branch so I would like to set a policy on the Active Directory Organizational unit. The settings I would like to enfource is a 5MB message size limit on the 384K connected branches and 10MB limit on the T-1 connected branches. I could set a limit based on the store itself, but I have each store is set aside for each affiliate bank so it can get SMTP addresses from the Recipient Policy. Any suggestions on other ways of setting Delivery sending/receiving messages limits based on a policy and not individually on each user.
