2.4 Controlling Synchronization Size Limits

Synchronizing large quantities of data between GroupWise and mobile devices can put a substantial load on the sync agents. The GroupWise Sync Agent controls the maximum size of the individual attachments that can synchronize with an item to mobile devices. The Device Sync Agent controls the maximum size of an item (along with all attachments) that can synchronize to GroupWise.

2.4.1 Controlling Maximum Attachment Size from GroupWise to Mobile Devices

By default, attachments are synchronized from GroupWise to the mobile devices if they are smaller than 500 KB. Attachments larger than 500 KB are dropped by the GroupWise Sync Agent and do not synchronize to mobile devices.

When a user receives an item on the mobile device for which attachments have not been synchronized from GroupWise, the item includes a list of the attachments that are on the original item but not on the synchronized item. This lets the user know that attachments are available in the GroupWise mailbox.

  1. In the Mobility Admin console, click Config.

  2. In the Maximum Attachment Size field, adjust the maximum attachment size as needed.

    This setting causes large attachments that exceed the size limit to be stripped from a message as it synchronizes from GroupWise to mobile devices. Small attachments that are within the size limit are still synchronized.

  3. Click Save to save the new setting(s).

  4. Restart the Mobility Service:

    gms restart

2.4.2 Controlling Maximum Send Mail Size from Mobile Devices to GroupWise

By default, if an item is larger than 500 KB when it is sent from a device, all attachments are stripped from the item before it is sent to GroupWise. In place of each stripped attachment, the user receives a text attachment indicating that the original attachment was stripped because of the size limit and what the size limit is.

  1. In the Mobility Admin console, click Config.

  2. In the Maximum Send Mail Size field, adjust the maximum message size as needed.

    This setting causes all attachments to be stripped from an item as it synchronizes from a mobile device to GroupWise if the size of the item plus all attachments exceeds the size limit.

  3. Click Save to save the new setting(s).

  4. Restart the Mobility Service:

    gms restart
