| So, I called Microsoft Product Support and it turns out it was caused
| by 2 different AddIns that were loaded in Outlook. One was the
| Windows Sideshow addin and the other was one of our Anti-Spam toolbar
| Add-Ins. Once I disabled both of these the error went away.

||
||| When I make an update to a meeting and press Send Update, I receive
||| the message, "Changes to the meeting cannot be saved. The meeting
||| has been updated by another person. Close and reopen the meeting
||| and then make your update."
|||
||| -When I close (without saving) and reopen I still get the message.
||| -The only way to bypass this message is to close Outlook and reopen.
||| -I am inviting a test user and a couple resources (2 meeting rooms,
||| 1 laptop (equipment))
|||
||| The meeting hasn't been updated by another person because I try to
||| update it as soon as I send it.
|||
||| Anyone know what is causing this?
