Exchange activesync Error 3005

Hi i have an SBS 2003 running exchange. I used to have an iPhone and had it synced with the exchange server (after much trouble).
I now have another user who needs to sync and iphone and for some reason I cannot get it to work.
The iphone reports it cannot connect to the server and in the server application log i get an error 3005 as follows:

Unexpected Exchange mailbox Server error: Server:
[] User: []
HTTP status code: [409]. Verify that the Exchange mailbox server is working correctly.

I know it definitely works because using the same settings on the phone it will connect to my mailbox. It must be a permissions issue somewhere but I am at a loss as to where.

Any help appreciated!

Can you test the active sync connectivity using the below link?

Good luck
The event 3005 is logged on the Exchange Server and not necessarily that there is an issue with ActiveSync. The HTTP status code in the event is more important and from that we can identify if there are issues with activesync or not.

In your scenario, we are getting HTTP status code 409 which might not result in an ActiveSync failure.

You can refer to for more information in regards to HTTP status code 409.

To fix this event:
1. URLScan is known to cause issues with ActiveSync. If you have it installed, then I would suggest to go ahead and remove it.

2. Verify the authentication settings on the virtual directories. It should be as follows:
Exchange - Basic and Integrated Windows auth
SSL: Turn Off

MicroSoft-Server-ActiveSync - Basic auth

In case you have 'exchange-oma' directory (KB 817370), then same settings mentioned above will be applicable to 'exchange-oma'.

Let us know how it goes.

Hi thanks for your help.
I have followed most of the steps in that EE article you linked and when I went to do the activesync test with my username and password it worked perfectly - which i expected it to seeing as i can sync my mailbox to the iphone.
However when i tried using the other users credentials i got a 403 error right at the end. I have attached the log of the test.

I seem to remember it took me forever to get my account synced about 9 months ago and it was something to do with setting permissions on the mailbox? But i really cant remember exactly what I did!

Any other thoughts?

Open in new window

Do you have ISA?

On Exchange-oma virtual directory, navigate to 'Directory Securtity' tab and click on 'edit' under 'IP address and domain name restrictions'.

Check the IP address mentioned over there and make sure the IP address is of Exchange Server. Apart from that there will be a loopback IP address. You can ignore that.

Also make sure SSL is disabled on the Exchange-oma

Let us know how it goes.

I i have SBS 2003 Std so I dont have ISA.
I went through the replace exchange-oma directory last night and now one of my users can sync perfectly. However, the other account still gets the same error and so does my account (that worked before). Very strange.

I have checked the IP Address and that is correct and SSL is definitely disabled on the exchange-oma directory.

The setup itself definitely works because one user is now syncing - however several other users still return a 403. Bizarre!
