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?

Are you the organizer?

After furious head scratching, Davidi asked:

yes.

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.

Hi Davidi,

we are experiencing the exact same issue, though somewhat inconsistently.
Did microsoft give you any explanation as to why/how the add-ins were causing
the behavior? We've been troubleshooting this for a couple of weeks now and
haven't had much progress...
