Error message in Console related to EWSExchangeWebServices

My Mail seems to be using a lot of memory and I've noticed the following error message recurring. Can anyone help me sort out what it means and what I might do to fix it?

Thanks

Just guessing here, but look at this page,

Does anything there "ring any bells" on anything you might have been doing recently? Of course I don't think any of that would have any relationship with the apple Mail app.

Thanks, but nothing sparks any fires. I've passed it on to the folks who host the exchange mail that I have as one of my mail providers.

Cheers

I get the EWS Assertion error every once in a while and Mail stops synching with Exchange. Here's what seems to fix it for me:

(MacOSX 10.8.2)

Quit Mail
Delete ~/Library/Containers/com.apple.mail/Data/Library/Preferences/com.apple.mail.pli st
Restart Mail

I had the this happen to me again and this time the fix was different. Turns out my Calendar and Contacts app didn't update it's password with my Mail account. I opened the other Appliacations and put my password in and Mail was fine again.
