Number of concurrent connections to Exchange Server. This controls the maximum number of simultaneous connections that the task is allowed to make to the Microsoft Exchange Server computer.

By increasing the number of connections, you may improve performance, although the default of five is likely to be the optimum value. However, each connection takes up one Microsoft Exchange Server Client license, so you may have to adjust the number of concurrent connections appropriately.

Remember that the Exchange Journaling and Exchange Public Folder tasks also take up Microsoft Exchange Server Client licenses. If you are short of licenses, you may have to balance the number of licenses between the tasks.

If you change this setting you must stop and restart the task to make the change take effect.

Maximum number of items per target per pass. The maximum number of items that are archived on a single run through its targets.

An Exchange Journaling Task archives a maximum of this many items from the mailbox on each pass through the mailbox. Setting this number much higher than the default of 1000 uses more memory and is unlikely to improve performance. If you do not have a backlog of items that are not being archived, do not change this value.

System mailbox. The mailbox that is used by the task when logging on to Exchange Server. Click Change if you want to select a different mailbox.
