I've read numerous other posts on this site about people having trouble with ActiveSync and error 85010014. Most seems to imply they are trying to set this up for the first time. My situation is a little different. I have SUCCESSFULLY been using ActiveSync on my WM5 device for a couple of months. OMA was working fine, OWA was working fine with SSL required. There were no problems. Then the other day ... BAM ... ActiveSync decides it want's to start giving me negotiate and authentication/SSL errors out of nowhere! Literally, the messages began to be logged on the Exchange server at 5:30am after months of no problems at all. I am at my wits end trying to get this resolved over the past couple of days. Luckily, I'm the only one in our organization using ActiveSync, so I can live with the inconvenience.
OWA still works fine, and mail flow is OK. We're running one Exch2003SP2 server on Windows Server 2003 SP1. This machine is dedicated only to Exchange, it is not a domain controller.
The only thing that has changed recently is that I brought another Domain Controller on line (the day before this started happening, which is suspicious), and also made it a Catalog Server. I don't see any reason why this would impair ActiveSync. If anyone sees a correlation there, please let me know.
So, I'm not quite sure what I'm asking in this post, other than for help getting my ActiveSync/OMA running properly again. Any thoughts are appreciates. Thanks.
