Some users face the problem of TouchDown looping to perform refreshes, resulting in a higher battery drain and slower operations.
This can also result in TouchDown displaying the message "Push Throttled, too many timeouts in 1 minute".
The following are the reasons we have found for this occurrence
If your server is not reachable by TouchDown, it attempts to connect repeatedly. However, if it tries and fails 5 times or more in a given minute, it gives up and waits for about 8 minutes before trying again
When TouchDown attempts to connect to the server for push notifications, there are some situations where sever misconfiguration can cause the attempt to fail. If TouchDown fails to connect for some reason, it will attempt a few times, and then throttle itself for about 8 minutes
In some cases, if your server has an Antivirus installed on it, and if the Antivirus has not been configured properly to exclude certain exchange folders from scanning, this can happen, and TouchDown will constantly think there are changes and try to sync these changes. If it happens more than 5 times a minute, it will throttle itself.

Sometimes certain types of messages seem to be generating inconsistent messages in Exchange 2003 in ActiveSync. The typical symptom would be EXTREME sluggishness. Here is a workaround for that.
First go to the main touchdown screen, and leave it there for about a minute. If you see the bottom right indicator constantly switching to green and after about a minute you get the "Push throttled" message, chances are one of the above issues are present.
