When you upgrade a BlackBerry® Enterprise Server instance, the upgrade process does not automatically add the new attachment extensions that the latest BlackBerry Enterprise Server version supports. You must add the new attachment extensions after the upgrade process completes so that the BlackBerry Enterprise Server can recognize the new attachments and send them to a BlackBerry Attachment Service instance for processing. The following list of supported file formats were added to versions later than BlackBerry Enterprise Server version 4.1 SP3: .amr*, .wmf, .wma, .pptx, .docx, .xlsx, .odp, .ods, .odt, and .ott files.

1. In the BlackBerry Administration Service, on the Servers and components menu, expand BlackBerry Solution topology > BlackBerry Domain > Component view > Attachment > Connector.
2. Click the BlackBerry Attachment Connector instance for the BlackBerry Enterprise Server.
3. Click Edit instance.
4. Click Supported Attachment Server instances.
5. For the BlackBerry Attachment Service instance that you want the BlackBerry Enterprise Server to send new attachments to, click the Edit icon.
6. Add the new attachments to the attachments extensions list.
7. Click the Save icon.
8. Click Save all.
9. Restart the BlackBerry Enterprise Server by performing the following actions:
   1. On the Servers and components menu, expand BlackBerry Solution topology > BlackBerry Domain > Component view > BlackBerry Enterprise Server.
   2. Click the BlackBerry Enterprise Server instance that you upgraded. Click Restart instance.

During the upgrade process for a BlackBerry® Attachment Service instance, the setup application does not turn on the new attachment distillers automatically. If you want the BlackBerry Attachment Service to process new attachments, you must turn on the attachment distillers for these file formats. The following supported file formats were added to versions later than BlackBerry Enterprise Server version 4.1 SP3: .amr*, .wmf, .wma, .pptx, .docx, .xlsx, .odp, .ods, .odt, and .ott files.

1. In the BlackBerry Administration Service, on the Servers and components menu, expand BlackBerry Solution topology > BlackBerry Domain > Component view > Attachment > Server.
2. Click the instance that you upgraded.
3. Click Edit instance.
4. In the Distiller section, in the Allowed column, turn on the attachment distillers that you want the BlackBerry Attachment Service to support.
5. If required, in the Distiller section, in the Attachment size (KB) column, change the file size, in KB, for the new attachments.
6. Click Save.
