I recently upgradeed to Exchange 2003 from 200 and since then I have users who are having problems deleting and changing calendar events for other users that they have permission to change. Is this a "feature" of Exchange 2003 and if so is it possible to turn it off? Thanks.

Clarify: Some users cant modify the shared calendars which they had access right before migrating to Exchange 2003, right? Can you describe more detail about the issue? Like: 1. What symptom occurred if users cant modify shared calendar? 2. Is there any error info appeared? 3. Version: Outlook 2003? As the limited info, I can only provide some general troubleshooting steps here: 1. Create a test user, then grant to access right of a shared calendar which involved with the issue, try to reproduce issue. Notes: In this way, we can isolate the issue to shared calendar or affected user who want to modify the shared calendar 2. Create affected users mail profile on a testing PC, and then try to reproduce issue Notes: It can isolate the issue to the mailbox on the server or the client PC 3. Try to re-set the delegate process for a affected user on a shared calendar

Hi,Stewy, did the suggestions help? How's the issue?
