Hello to all

I am unable to view a user’s calendar when scheduling a meeting. I have checked the Free/Busy option within calendar preferences and it's set to publish 6 month of calendar entries. In order to resolve the problem, I run the 'Outlook.exe /cleanfreebusy' command on the user ‘s PC but I am getting the following error message: “Unable to clean free / busy information on server”.

Then I  follow the instructions from  http://support.microsoft.com/default.aspx?scid=kb;EN-US;958443 and still getting the same error message of “Unable to clean free / busy information on server”.

Anyone know how to resolve this. It's only happening with one user. The user’s PC is running Windows XP SP3 with Outlook 2003 and running on an Exchange Server 2003.

Thanks in advance

Are you running Outlook with cached exchange mode enabled?  If so, try turning it off and see if that resolves the issue.

Outlook is running non cached exchange mode.

I assume you've already seen this similar post?  http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_22450473.html

The author's solution seems to be related to the LegacyExchangeDN attribute for the problem user not pointing to the correct server.

Have any server upgrades/migrations happened in your environment recently?

So you've already deleted the instances of PR_FREEBUSY_ENTRYIDS in the problem mailbox, as detailed in that Microsoft KB article, and the issue still persists?

I did come across this link (http://wadingthrough.wordpress.com/2006/07/31/unable-to-clean-local-freebusy-information) but it looks a little outdated and everyone there mentions the same procedure of using MFCMAPI as detailed in the Microsoft article.

Any related errors in the event logs on the Exchange server?  Surely there must be something in there related to public folders or the Schedule+/Free-Busy info.

On the Exchange server, probably the application log but maybe also the system log.
