Have some MAC computers in the Windows environment. They have Office 2011 MAC installed on them. Just found out that they can't send over like 4 MB in email message. However, they log into Windows PC and no problems. Not sure where the settign is for this. I had lookd around and found it is a setting on the server but nobody seems to know where. Could somebody tell me where to find this? Any help greatly appreciated.

Hi 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.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

I looked at the EWS file but it does not contain the line of code stated in the article. Do I need to add this to the file? Is that the easiet way to make the change?
