It's the iphone. Restart the device quickly then delete the entry and try again. I have seen this issue myself. If you check the headers you will find that the messages are being generated by an SMTP at apple.

I've been a member of serverfault since 2008(ish) when I started as a Network Manager role for a small pharmaceutical company. After 3+ years as a network manager, I accepted a role of Deskside Support for a large rail infrastructure business. While the role was perhaps a backwards step technically, it would provide me with the exposure to large networks and a more promising career path. As of last year my company has been acquired by Siemens, which resulted in a nearly 2 year IT integration project. I'm currently employed as an Infrastructure Support Engineer for Siemens. This role involves support of Sun Solaris 10, I have a little knowledge of Unix/Linux gained from training courses. Serverfault has always been an incredibly useful tool for me during the years and if those answers that are not applicable are always enlightening and will continue to prove it's value to me as this role develops.

This only appears to be affecting one user, but this user sends a calendar invite, then starts sending multiple invites there after. We are using Exchange SBS, with the user using Outlook 2007, also the user has an iPhone which he has yet to confirm if he used the device to send the invite.

The problem only seems intermittent but is obviously a problem, I'm not entirely sure if it's Outlook or Exchange.

One more thing I should point out is that the user is based remotely and isn't always in the office, I do have access to Exchange however.

Any ideas?

I have yet to find the cause or a perminate solution for this myself either but that will stop the behavior for the time being. This was a nightmare for us as it happened on a Calendar invite with more then a dozen clients on it.

They use Outlook 2007 on their laptop and Mail on their iPhone. Exchange is SBS 2003
