I have a fix for this already but I don't really understand why this fixes the problem.
We have resource calendars that were migrated from Exchange 5.5 to 2003 to 2007.
Users who have access are not seeing changes when looking at the shared calendar. When I look at the users "Send As" permissions the "NT Authority\Self" is listed. I thought that would be right but I look at a freshly made mailbox and it
isn't there. I remove the "Self" account from the mailbox. I verify the Self account is available through the "Full Access" permissions and it is.
This appears to resolve the issue.
Can anyone tell me why?
Thank you.
