unable to access shared calendar

[Guest]

When a computer has been idle or if Outlook has been minimized, shared
calendars get "lost". By that I mean a shared calendar will be open, then
the computer is left alone and when the user goes back to look at that
calendar it is blank with the following error "Unablel to display folder.
Microsoft Outlook could not access the specified folder location. Item could
not be found." If the user clicks to Mail, then back to calendar, the shared
calendars reconnect. This is happening on more than one computer. This is a
new problem. The version is Outlook 2003 SP2, Exchange Server Std. 2003. XP
Pro SP2. The last updates installed were for XP, KB's 935839 & 933566.

Any assistance would be greatly appreciated.

Sounds like a network connectivity issue. Are you using cached mode and are
the shared calendars cached? (look on the acct settings, more settings
dialog).

The default is set to cached mode. We have tried it both ways. There are no
networking issues that I know of. I have seen many postings about this
problem, not here, but searching google. Nobody has a clear answer for this.
We have tried deleting the ost file, reassigning permissions to the shared
calendar, clearing the cached mode setting, nothing has made any difference.
Plus it is not happening to all users. I personally have not been able to
reproduce the problem but have seen it happen with two systems. Usually if
there is a network problem a blurb comes up in the tray letting you know the
connection to the server has been lost. No such notification appears when
this happens.

what firewall are you using?

I appreciate your attempt to assist with this. This is not a firewall issue
that I am certain of. The Exchange 2003 Std. Ed. server and the users having
the problem are all on the same subnet, they are not passing through a
firewall. I have been informed this is a known issue. If I can get the KB
article I will post it here.

I am having exactly the same problem at the moment but the worst thing
is, I have had this problem before with one user and solved it. But
cannot find the solution anymore .

Have you tried accessing the delegates tab in outlook? the ones who
have these problems can access the tab but it takes for ages before
the tab is shown once clicked.

Have tried commands like Outlook /cleanrules, /cleanfreebusy and /
cleanreminders. Non of them help unfortunately.

I actually have a case open with Microsoft about this. So far no answer but
when I get one I will post it here. The following are the hoops they want
jumped in order to resolve.

Based on my experience, this issue may occur in various situations. Would
you please help me to collect some information for my further research?



1. After the issue occurs, if we restart Outlook and switch to Calendar
view, click the shared calendar under "Other Calendars", does the error
message still appear?

2. Would you please help me to capture a screenshot of the error message and
send to me?

3. Can the issue be reproduced every time using Outlook?

4. Does the problematic user account (the users who encounter this issue)
have their mailboxes placed on the same Exchange Server? Do they in a same
security group?
