HTC EVO 4G :: Activesync Error Occurred On Computer Running Exchange Server 2007

Yesterday I noticed that my corporate email (i.e., Activesync) were no longer being synced to my HTC Evo (running Android 2.1). A little troubleshooting revealed the following: I could still send emails from the Evo via the synced account. My synced calendar and contacts continued to updated without error. I believe my company is running Exchange 2007, but I am not sure (and since the help desk does not officially support syncing to non-Blackberry phones, I doubt they will help me details or troubleshoot). In any case, a little Googling revealed that: This error is not specific to the HTC Evo (it happens on other Android phones).

A few folks reported that the error occurred seven days after Activesync was initially configured on their Android phone, and would reoccur approximately every seven days. In my situation, the only unusual item to note was that my mailbox had reached capacity on the Exchange server sometime during the period when my phone stopped syncing. However, freeing up space in my mailbox did not resolve the problem. In the end, I resolved the problem by deleting the Activesync account on the Evo and re-creating it. After doing that, all emails synced successfully.
