Exchange 2003

I have several users complaining about not receiving emails with attachments. Things seem to be working fine with small files, but anything over 2MB it seems is not coming through. Where in Exchange could this setting be? I am using Exchange 2003.

There are a few places whereby you can restrict the e-mail size limit.
Check in System Manager - Global Settings - Message Delivery (Right-click - Properties) - Default tab

Also in System Manager, find your mailbox store (Servers - servername - First Storage Group), Properties - Limits.

If it is only affecting one person, you should check within their AD object under Exchange General tab - Delivery Restrictions.

thank you kindly for your assistance
