After migrating from a SBS 2003 to a new SBS 2008 with exchange 2007 I am unable to get my clients' blackberries to connect through BIS. I have been working with RIM to try and get this resolved and they have made mention that when they try to connect using the OWA settings, the connection is immediately dropped after it is made showing either a 404 error or 440 error. They have basically told us to check and make sure Web Dav and/or EWS are configured correctly. In my past experiences it was only necessary to make sure both of these services were enabled, which they are. here is the last communication I was sent from them...
Or network team has done some telnet sessions and other tests and they believe they have found where the failure is occurring.
When we send this command:
PROPFIND /owa/livia/ HTTP/1.1
OWA is returning a 404 error:
HTTP/1.1 404 Not Found
Would you be able to confirm Web Dav and EWS are configured correctly on the server?
Do you have any other users on this server who have gotten OWA to work on their Blackberry smart phones or does it seem to be an issue with this specific mailbox?
it is not an issue with a specific mailbox as there are 2 Blackberry users at this client. if more info is needed please let me know I have also attached the log files that were sent to RIM for additional info...
This issue has been very perplexing for me, and my client is getting upset that I cannot seem to find any answer that will get this fixed.
