This request is out-of-date

[ITPRO]

Messaging Environment:

Exchange 2003

Outlook 2003

User 1 sends a meeting request to User 2,3 4

User 2 is configured with delegate access to User 3, 4 Calendar.

User 2 accepts the meeting request for User 3 and 4.

User 2 can accept meeting request for herself and User 3 successfully. But
when she tries to accept the meeting request for User 4 it says "This
request is out-of-date" in the Invited Event Window.

This mostly happens to Executive Assistances who are managing calendars for
multiple Executives at the same time.

User 4 also has iPhone.

If you need more clarifications, please let me know.

Please help.

I too am experiencing this issue, with the following circumstance:

User 1 is a delegate on Users 2, 3 and 4 calendars.

User 1 creates a meeting on User 2's calendar. If User 1 looks at User 2's
calendar after doing so the meeting appears normally. However when User 1
receives the meeting request (that says "From User 1 on behalf of User 2")
it says "This request is out-of-date" at the top. Also, when going into
User 2's calendar, User 1 is unable to add more attendees to the meeting
(Add Others is grayed out). This is only happening on User 2's calendar.
Adding meetings for Users 3 and 4 work fine. User 2 has a new iPhone 3GS.
