Over the past few months i have seen an increasingly amount of users
that have been having trouble updating meetings. The error seems very
sporadic and there seems to be no rhyme or reason to why we are seeing
this error. Most users complain that they get the error when adding an
attendee, and or chaging the time. Any help would be greatly
appreciated, i have searched long and hard and have had no luck. We
are running exchange 2k3 sp2 on two mailbox servers and clients are
running Outlook 2003 with sp2. I have tried creating new profiles,
installing sp3, clearing froms cache.

The errors include:
The item could not be saved because it has been changed by another
person. Do you want to save a copy in your default calendar folder? If
you click yes, you need to copy and paste your changes from the "copy
of" intem in your default folder int a new update for this meeting.
