On my Exchange 2007 server, I ran TSM as backup client. TSM was scheduled to backup every night at 11 pm., In the mean while, I had scheduled the online maintenance in Exchange 2007 daily from 0am to 7am.
The following error occured every day in my event viewer

PFDAVADMIN errors and solutions
Due to limited functionality in Exchange 2007 to manage public folders, many Exchange administrators use PFDAVADMIN to manage their public folders. In my opinion, setting permissions is the most important enrichment of PFDAVADMIN. I still can’t believe Microsoft did not implement it in their Exchange Management Console (EMC). Nevertheless, we may be glad that they DID make a GUI for creating and deleting Public Folders. :)

Convert Legacy Mailbox to User Mailbox in Exchange 2007
After an upgrade from Exchange 2003 to Exchange 2007, you should immediately uninstall the Exchange System Manager (ESM) on any desktop in your organisation. This is because the ESM enriches your Active Directory Users And Computers with some Integrated Exchange Tabs. These tabs, that come with ESM 2003, do not work with Exchange 2007. And if they do work, you should not use them :)
