Messaging Records Management (MRM) Exchange 2007 Entire Mailbox

If you are using managed folder policies and would like to apply deletion rules to folders outside of the default folders such as a user that creates a folder at the root and not in the Inbox, you may have to work with "Entire Mailbox"

I have used this setting in the past and it can cause havoc. In other words it will apply to every single folder, including calendar, contacts, etc. when you use it.

The only way to ensure that it wont apply to a specific folder is to have that managed folder part of the same policy.

So if you have Entire Mailbox selected to delete emails after 90 days, everything in Outlook older than 90 days will be deleted. If you also have a Calendar managed folder policy for 120 days as part of the same policy, which includes Entire Mailbox, the 90 day rule wont apply to Calendar. The calendar items will delete after 120 days and everything else 90 days.

Another option is to choose for the Entire Mailbox policy to only delete emails and not all items. IF you do this then it will only delete emails for the entire mailbox and not items like calendar entries, tasks, etc.

Be careful.

Exchange 2007 File Share Witness Multi-subnet clustering

If you are placing the file share witness at the same site as your active Exchange 2007 server, when you have a primary site failure Exchange will not be able to start at the DR site. This is because it will only have 1 of 3 votes as both the quorum and the active are down.

You will have to run a /fq (net start clussvc /fq) to force the quorum to start at the secondary site.
