Event ID 8207: Error updating public folder with free/busy information on virtual machine EXCHANGESERVERNAME. I have this occuring in the application event log several times daily.

Is there anyway I can hide my availability completely or make it available to just the people I work with?

By default, only your availability time is being shown without any details so all the details remain private.

This is the output of Get-Public Folder -Identity "\NON_IPM_SUBTREE\SCHEDULE FREE BUSY" -Recurse |Select Name, Parent Path, Replicas |FLName : SCHEDULE FREE BUSYParent Path : \NON_IPM_SUBTREEReplicas : Name : EX:/o=Organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)Parent Path : \NON_IPM_SUBTREE\SCHEDULE FREE BUSYReplicas : Also, starting at 6PM last night, the server started logging the following into application log: Source: MSExchange FBPublish Category: General Type: Error Event ID: 8207Description: Error updating public folder with free/busy information on virtual machine SERVERNAME.

This is logged precisely every 50 minutes - started at , then at , then at and so on.

I’m working in a large organization with an Exchange account and I recently noticed that everyone within the company can see my free/busy information.

I can understand this importance for a small company or a single department but to everyone else in a large company, I find that my availability is none of their business.

This pretty much narrows it down to a firewall problem, at least as far as Outlook 2007 is concerned.

Firewall is a Checkpoint NGX, configured for static NAT with ports 80 and 443 open.

Autodiscover seems to be configured correctly, but I guess it's two different problems.
