Shorten the download interval on the Exchange Server 2003 Pop3 Connector

The shortest interval to download user email with the Exchange Pop3 connector is 15 minutes. Too long for most people. To shorten that to 5 minutes, you have to update/add a registry value in this key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SmallBusinessServer\Network\POP3 Connector

Add Dword:

“ScheduleAccelerator”=dword:00000003

 

It works by dividing the default schedule interval by that value. For example, the server connector is set to 15 minutes, the lowest setting. Set the reg value to 3, so 15 divided by 3 equals 5. This makes it a 5 minute interval.

    Thanks, 15 minutes is far too long to wait. Linux & fetchmail can be scheduled every 5 minutes. And if you are paying for tech support to sit around and wait for 15 minutes a time……..

    Another option would be to use Popcon (christensen-software), which not only allows to shorten the download interval, but also to use pop over ssl connections (useful when using gmail for your domain - google apps for instance)

    Erik, nice tip, I’ll keep that one in mind. Some clients might be better off with that one, and I didn’t even know about it.
    Also, I agree about the Fetchmail thing. I like Fetchmail, unfortunately some clients can’t use it in there MS only environment. But hearing “fetchmail” gives me an idea for mail archiving… but that’s a post for another topic!
