When you refer to any event log message you should post the entire message. -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." .

I don't have a good answer for you for this. Do you have any third-party Exchange Web Services-based applications? -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." .

Can anyone help me out.. Thanks, TRI Use a network monitor. You can also go through each mailbox and remove the devices that haven't sync'd for a couple of weeks. But if it's some application using EWS or Web Services that won't help. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

I'm having the same problem. From the IIS logs, it seems to be related to Project Server, which of course creates subsctiptions for its Alerts and Notifications, but I don't know how to identify the owners of the subscriptions, or even tell if these events actually matter. We have many users who don't have dedicated computers (just Outlook Web Access), as well as a number of users who do have outlook, but are on laptops which are of course not always connected to Exchange. And then we also have users with sync set up on their smartphones, which also may not always be reachable. Any advice on how to at least determine if these errors should be ignored, or in the case of Project Server alerts for users who are not always connected to be configured for Pull rather than Push subscriptions?
