Resubscribing automatically
Exchange mailboxes subscribe to a room in Planon ProCenter. If either Exchange or Planon ProCenter is down, the subscription of these mailboxes can be lost.
To detect and resolve such situations as early as possible, a scheduled task is available to check for lost subscriptions and resubscribe to the mailboxes automatically.
The subscription mechanism will also try to subscribe to mailboxes whose status is Subscription failed. In case of a Configuration error status, the mailbox will not be included.
Once the subscription is established successfully, the subscription mechanism will perform synchronization between Exchange and Planon ProCenter based on the Synchronization on subscription setting.

For more information on Synchronization on subscription settings and scheduled tasks, refer to Connect for Outlook - Administrator's Guide.

•    If the scheduled task is active while you are configuring mailboxes, it will try to resubscribe to mailboxes for which subscription failed due to an incorrect configuration.
•    If the configuration is now correct, the mailbox will automatically be resubscribed (or you can resubscribe manually).
•    It is recommended to set the scheduled task to Inactive when configuring mailboxes.
