> Hi,
>
> I have a customer that has more than 1000 Outlook 2007 SP1 clients that is
> storing all their mailboxes on an Exchange 2003 server.
>
> The customer has a problem with only one mailbox. The mailboxes belongs to
> one of the executives. The problem started suddenly early this week. Until
> then he did not have any problem.
>
> The problem is that none of his delegates are able to create new
> appointments in the problematic mailbox calendar. They are able to view his
> calendar, and everyone sees his free/busy information.
>
> The error the delegates are receiving is:
> "Cannot open the free/busy information. Cannot locate recurrence
> information for this appointment."
>
> I tried to recreate the free/busy information on the server, but when I run
> outlook /cleanfreebusy on his mailbox, I get the following error:
> "Cannot clean your free/busy information on the server."
>
> I manuly deleted the free/busy information from the public folder on the
> server (using OWA and non_ipm_subtree), and tried to run outlook
> /cleanfreebusy again, but got the same error.
>
> I switched to Outlook XP, and was able to create the free/busy information
> on the server using outlook /cleanfreebusy.
>
> I also tried deleting the local free/busy message of the mailbox using
> MFCmapi, but that did change the way this mailbox behaves.
>
> Summary:
> I can see the free/busy information message on the server using OWA, and all
> the users can see the free/busy information of the mailbox.
> Outlook 2007 users can view free/busy information for the mailbox.
> Outlook 2007 delegates cannot create appointments on the problematic mailbox.
> I am unable to "reset" the free busy information of the problematic mailbox
> using Outlook 2007.
> Outlook XP delegates are able to create appointments on the problematic
> mailbox.
> I am able to "reset" the free busy information of the problematic mailbox
> using Outlook XP.
>
> This is not a "Server" problem because all the othe mailboxes works fine,
> and Outlook XP works OK.
>
> It looks to me like the data on the mailbox, the user, or the free/busy
> information is not handeled correctly by Outlook 2007.
>
> I will be happy if someone can help me solve the problem.
>
> Thanks,
>
