Shared Calendar Attendees Disappear In Outlook

[@dmin]

Hello,

I am having an issue in 4.5.7 NE where attendees disappear from meetings on a shared calendar when viewed through Outlook. This behavior is not observed through the web client. I have a public read-only 'company calendar' that auto accepts all. Employees will invite it when they want certain meetings viewed by all staff.

When you first add the calendar share in Outlook the schedule populates and all is well. Throughout the day attendees start to disappear until only the organizer shows for each meeting. Close the shared calendar connection, reopen, and they all return (for awhile).

Also, the dropped meeting information is not the same for each and every Outlook user.

Setup:
ZCS 4.5.7 NE on RHE 5.0
WINXP SP2, Outlook 2003 SP3, ZCO 4.5.373

Can you list the exact repro steps so we can investigate?

1. Open Outlook

2. File > Open > Other User's Mailbox >[company calendar share user]

This resource auto accepts everything, it contains 480 objects, 80 of them reoccurring. One user has manager access to it, 25 others read-only. Half of the objects were imported from a .pst with the migration tool, the other half have been created new since the migration.

3. Allow time for the calendar to synchronize.

4. Immediately view any of the meetings and attendees/free-busy information shows correctly.

5. If you view the same calendar later in the day the attendees have disappeared on the majority of the meetings. Information loss is different from client to client. It does not seem to matter if the user with manager rights ads meetings directly to the calendar, or employees create their own and invite the 'company calendar share'.
