I have no personal experience with OL 2011 yet, but I do know that it's using EWS (Exchange Web Services) instead of MAPI. You MIGHT check IIS configuration for maximum file transfer sizes and such.

We can use the windows client and we can send messages up to the max set limit 25MB. I have checked all of the Exchange send and receive connectors from global to individual mail box and there is nothing set less that 25MB. Outlook 2011 bug? Any help would be appreciated.
