Hi Experts - I'm stumped.
I have a SBS2003 server with Exchange2003SP2.
I have Windows Mobile handsets which sync over ActiveSync - i-mate KJAMs on Windows Mobile 5, and HTC TyTN II / Touch / Touch Dual handsets on Windows Mobile 6.1
The windows mobile 6.1 handsets will not download email attachments - if you click on an attachment the green arrow appears saying it will be downloaded, but then it disappears after a few seconds. No error message is given on the handset.
Here's some log snippets:
Here's what a *failed* download to a Windows Mobile 6.1 device looks like in my IIS log.
2008-11-03 04:49:53 W3SVC1 192.168.10.4 GET /exchangeDAV/(username)@(domain).com.au/Inbox/PDF%20File%20Attached-285.EML/1_multipart_xF8FF_2_PDF%20File%20Attachment_328619.pdf - 80 - 192.168.10.4 Microsoft-Server-ActiveSync/6.5.7638.1 401 1 0
This message repeats ~4 times, each time 401 unauthorized.
Here's what a *sucessful* download on a WM5 phone looks like in my IIS log
2008-11-04 00:26:30 W3SVC1 192.168.10.4 GET /exchangeDAV/(username)@(domain).com.au/Inbox/FW:PDF%20File%20Attached.EML/1_multipart_xF8FF_2_PDF%20File%20Attachment.pdf - 80 (NETBIOSDOMAIN)\(username) 192.168.10.4 Microsoft-Server-ActiveSync/6.5.7638.1 200 0 0
As you can see, the WM5 device sends a username, the WM6.1 doesnt. Why?
Everything else works fine on the WM6.1 device (exchange sync wyse). OWA also works and can download attachment. Outlook RPC/HTTP also works and can download attachments.
