Yesterday, some users were experiencing 500 Internal Server errors when trying to attach files (small PDF’s) to email, and today the OWA issues seem to be spreading. Users are also reporting errors with mobile phones / activesync. Any ideas on where to look for an issue here?

What version of Exchange are you using? Have you seen this article? http://support.microsoft.com/default.aspx/kb/894965?p=1 Santhosh Sivarajan | MCTS, MCSE (W2K3/W2K/NT4), MCSA (W2K3/W2K/MSG), CCNA, Network+ Houston, TX http://blogs.sivarajan.com/ http://publications.sivarajan.com/ This posting is provided "AS IS" with no warranties, and confers no rights.

Yes....it is Exchange 2003. Here is what we have seen so far: 1. OWA emails with attachments not being sent. HTTP/1.1 500 Internal Server Error 2. Mobile devices receiving an Activesync error. ActiveSync encountered a problem on the server. Support Code 0x85010014 Thanks

Anyone have thoughts on this?

Some additional info:It is not all users with OWA, it began with 2 and has increased to a couple dozen. They cannot send an attachment and it is not all attachment only some types. Another user could not save a draft email. It is about 7 users with Mobile Devices and it is only ActiveSync. any one have any ideas on this?
