- Fail over time limit (minutes) Enter the length of time in minutes that the currently selected peer Exchange server must be inaccessible before the MAS initiates a search to locate another peer Exchange server. The range is 1 to 720. The default is 1 minute.
- Maximum ping time (ms) Enter the number of milliseconds the MAS may take to receive a successful ping with a peer server in order to select it for backup messaging service. The default is 1000 milliseconds.
- Fail back idle time (minutes) Enter the number of minutes that voice ports on the MAS must be idle before the MAS attempts to return service to the primary peer Exchange server. The default is 15 minutes.
- Enable unlimited fail over attempts Select to allow the MAS to check indefinitely for another peer server to provide service, if the primary peer server fails. Avaya recommends that you select this option. The default is selected.
If the check box is cleared, the Fail over attempt limit field is enabled and you must set a limit for fail over attempts.
- Fail over attempt limit Enter the limit for the number of attempts the MAS makes to find another peer server, if the primary peer server fails, before switching to offline mode.
The range is 1 through the number of fail over peer servers you have configured on the system.
- Monitor exception list Displays a list of the peer Exchange servers in the voice mail domain for which you can control monitoring.
Notes:
- The Modular Messaging system only recognizes this list, when the Monitor exception mode field is set to None.
- Typically, this list is used to prevent the monitoring of Exchange servers across WANs.
- Servers appearing on this list will not be considered for fail over service. You may wish to add a peer server to this list, if that server typically has high traffic volume and its performance would be significantly impaired, if it were selected for fail over service.

Adds a line to the list. You can then enter the name of the server or select the server using the browse (...) button.
Deletes the server selected in the list. The system prompts you to confirm the deletion.
- Monitor exception mode Select the option to determine how the peer Exchange servers listed in the Monitor exception list are monitored by the MASs.
- None The servers in the list are not monitored by the MASs.
- Automatic (Default) Servers are monitored as normal by the MAS and the list is disregarded.
- Monitor new servers Select to monitor automatically any new Exchange servers added to the voice mail domain.
If this check box is not selected, the MAS adds any new Exchange servers it encounters to the Monitor exception list.

Note:
Clearing this check box is typically done in conjunction with selecting None for the Monitor exception mode field. This is to prevent accidental monitoring of servers across a WAN, which can degrade system performance. You should consider using these settings, only if your Exchange environment is large and distributed across a WAN.
