We're running on Exchange 2007 and our email clients are a mixture of Outlook 2007 and 2003. We have cached mode unchecked as we've had problems with mail and calendar appointments updating.
Lately, we've been noticing that other people's calendars that are open on a user's calendar, sometimes disappear when they close and reopen outlook.We then have to open each calendar back up.
We can't find a pattern as to why this happens but its certainly very annoying. Some users never have this problem while others, it occurs regularly.
Any assistance in resolving this will be most appreciated.
