Event ID 3005 every 5 minutes event log activesync android htc incredible


Had an Android-based (Android version 2.3.4 Software #4.08.605.2) HTC Incredible phone which kept loading up the Windows log files with error 3005 on a Server 2003 box with Exchange 2003 sp2.
This machine is the front-end exchange box in a FE BE setup and uses SSL.  

Note: Activesync works correctly with no errors on the device, but the errors in the logs were troubling.

Turns out, this is a common complaint on the internet forums and there isn’t a clear “silver-bullet” fix for it, but here is what worked for me:

  • Delete and recreate the Exchange account.  Do a Manual Setup of the server details and leave the Domain blank.  Instead, enter the domain as part of the Username.. that is: domain/username

So far this seems to have solved the problem but if it comes back I will provide an update.

  1. The solution described here is great. What more can be done is that open IIS>Right click on default website>Choose Properties>Advanced. Click add and enter the following details:
    IP Address= (All Unassigned), TCP Port= 80, Host Header Value= Blank. Click Ok. This quick fix has worked for me when I faced error 3005.
