There may be situations where an immediate update of the mailboxes and subscriptions may be useful. Some of the situations are mentioned as follows:
List of mailboxes has changed significantly due to changes in the Symantec Email Submission Client administration console or changes in the Exchange server.
Exchange has dropped all the Symantec Email Submission Client mailbox subscriptions.
To start a system update manually
In the Update Now field, select the Exchange servers to update. The Update Now operation performs the following during the manual update process:
Determines the list of mailboxes for spam submissions
Creates, renames, or removes the spam submission folder
Subscribes to Exchange notifications for all mailboxes that are either created or renamed
Removes the Exchange notifications for all removed mailboxes
For Email Submission Client to process any email currently submitted for spam, select Perform pending submissions along with enumeration. If this option is not selected, spam submissions may not be processed until a scheduled update or service start update.
If you suspect that the Exchange has dropped the Email Submission Client subscriptions, select the Perform force subscription option. If this option is not selected, subscriptions are not processed until a scheduled update or service start update. You can perform a force subscription in any of the following scenarios:
When you reset IIS service on Exchange CAS or CAS server restart
When you move the mailbox to another mailbox store on the same Exchange server
When you dismount and mount the mailbox database
When database failover happens in Exchange server 2010 Database Availability Group (DAG)
When you change the port for Email Submission Client web service
When cluster failover happens in Single Copy Clusters (CCR) or Cluster Continuous Replication (CCR) Exchange 2007 cluster
