Udated appointment receives message "This is out of Date"

[paul Macefield]

Hi

One of our users updated an appointment to a new day,
using send update. However her intended recipients Outlook
client didn't move the appointment to new day, with it
still being "held" in the original appointment day.

The Yellow bar on the recipients appointment said

"This is out of Date"

Very odd, as two other recipents appointments were both
move to the correct day.

I couldn't replicate the problem.

Initial thoughts lead me to believe it was problem with
Free/Busy search and I was going to run the switch to
clean that.

Any thoughts?

THanks Paul
