I tried to send a PSD file from a client’s PC to my Exchange mailbox using my Gmail account and its 20 MB attachment size ability. Shortly after i sent the message and attachment I received a 5.2.3 error message which indicated the attachment was too large. WTF! We can’t have free email services provide larger attachment capability than our Exchange server.
Here’s how I increased the attachment size limit:
Use the Exchange System Manager and right click Message Delivery. Click the default tab and set the size limits.
