Changing the polling interval for the Exchange FDS

The Exchange 2007 File Distribution Service is responsible for keeping the OAB on the CAS in sync with the mailbox server. The default setting only polls the OAB every 8 hours. This could mean that a change you make doesn’t make it to the Outlook clients until well over a day (if you leave the OAB creation to the default once a day)!

To change this setting to e.g. every hour (60 minutes) use this command:

Get-OabVirtualDirectory| Set-OabVirtualDirectory -pollinterval 60
