Q: Is their any way to increase the scheduled time for pop connector to retrieve mail from 15 minutes to less time?
A: This is officially unsupported, but you can try the following method.
(Warning If you use Registry Editor incorrectly, you may cause serious
problems that may require you to reinstall your operating system.
. Use Registry Editor at your own risk.)
1. Click "Start", click "Run", type "regedit" (without the quotation
marks) in the "Open" box, and then click "OK".
2. Locate and then click the following registry subkey:
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SmallBusinessServer\Network\POP3
Connector"
3. On the "Edit" menu, point to "New", and then click "DWORD Value".
4. Type "ScheduleAccelerator" (without the quotation marks) as the entry
name, and then press ENTER.
5. On the "Edit" menu, click "Modify".
6. In the "Value data" box, type the value that you want, and then click
"OK". To determine the polling interval, the value that is configured on
the "Scheduling" tab in the GUI is divided by the value that you type for
the ScheduleAccelerator entry. For example, if a 15 minute interval is
specified in the GUI and you set the value of the ScheduleAccelerator
entry to 3, the connector will poll ever five minutes.
7. Quit Registry Editor.
