Some of us has a few more ActiveSync partnerships configured than the average user. Not because we’re able use all devices at the same time, or because we buy a new device every week. But because we test a lot of devices, fire up a couple of emulators, and generally have a number of devices passing through our hands.
After I upgraded my main Exchange 2010 box to Service Pack 1 and tried to do some testing I was met with a strict mail in Outlook Web Access informing me that I would not be able to establish more ActiveSync partnerships because I had 41 devices defined at the moment, as opposed to the maximum of 10 devices allowed. Say what? That’s right – by default Exchange 2010 Service Pack 1 will only allow you to have 10 devices.
The reason for this is that Service Pack 1 introduces a new feature called “Throttling”. It’s not really a bad idea, and it doesn’t apply only to ActiveSync either. It allows you to restrict how much resources any one user can consume so you don’t have resource hogs connected with 10 computers, 40 devices, and then some at a time. (Ok, maybe those numbers are a bit far-fetched but you get the point.)
I’m not going to go into details how this works, but you can control these settings with the Set-ThrottlingPolicy cmdlet.
To change the number to 50 (just a random number) run the following cmdlet:
Set-ThrottlingPolicy –EASMaxDevices 50 –Identity DefaultThrottlingPolicy_hex_string
To find out the “Identity” (that I shortened to “hex_string” above) to use you can run Get-ThrottlingPolicy first, and locate it there.
Ah, that’s better – now I can fire up another box full of devices and scatter around the house 🙂
