We are currently using Outlook 2007 and we have had several users including myself get an error message when trying to update and send a calendar invite.
The error does not occur everytime but occasionally. One user says that she sees it weekly, but she schedules a lot of meetings.
The message is:
Changes to the meeting cannot be saved. The meeting has been updated by another person. Close and reopen the meeting, and then make your updates.
The problem continues even when you close and reopen the invite. Closing and opening Outlook again seems to fix the issue but the user is not satisfied with that answer.
SP-1 is applied to the 2007 Client.
I have seen the article http://support.microsoft.com/kb/937494
-this fix is rolled up into SP-1 from my understanding.
I have attached the screenshot of the error to the post.
Thanks in advance,
