I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I would take a look at the users device and see if they are sending any large attachments or anything that might exceed the limits.  

Here's a decent article that describes the issue, assuming this is the same.
