This chunk of code is what was limiting ActiveSync devices from sending more than 10MB messages. What I found was a web.config file that had a message size limit setting for ActiveSync.Ĭ:\Program Files\Microsoft\Exchange Server\v14\ClientAccess\Sync\web.config has the following lines of code: Just to be sure, I checked the DB and users mailbox for any quota limits, but everything looked fine. I was able to replicate this issue with multiple devices connecting with ActiveSync. The strange thing with this is that the message limit of the environment is 50MB. They were receiving a message stating “The message was rejected by the server.” I started looking into the issue and found that the problem occurred when the user was trying to send attachments that were greater than 10MB in size.
I received a complaint today that a user wasn’t able to send an email with multiple attachments from their iPad.
