We migrated from exchange 2003 to 2010. All mailboxes are locate in 2010 now. Next, we are replacing client computers from windows XP with Outlook 2003 to Windows7 with Outlook 2010.
Some user reported "another person's calendar entry that deleted long before have restored".
I know http://support.microsoft.com/kb/2685949 (japanese only), but this KB talk about entry disappear. not about reappear.
Anyone have information about this issue?
