I don't think I can get the President of our company to pay for a commercial certificate right now. This is the only mobile device that would be using ActiveSync. ________________________________ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Chris Wall Sent: Tuesday, April 21, 2009 10:01 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Problem setting up Microsoft Exchange Active Sync That would be the problem... This is the only reason that I went with a well known Cert Authority (and one that Windows Mobile as well as other Mobile devices will accept). Paying for the Cert will save you many hours of troubleshooting with Mobile devices and will keep you from having to physically touch each device to force the Cert to be accepted (this in itself is a pain).

Our OWA url is https://owa.all-mode.com The mobile device belongs to one of our sales guys, it is a PALM Treo 700wx with WM 6.0 software. I will check the links you provided next.

Windows Mobile devices recognize only a small # of Certificates (especially older Windows Mobile devices). If you are having issues connecting, the issue most likely is that the Cert you are using on your front end is not an accepted one for Windows Mobile devices. See this: http://support.microsoft.com/kb/915840 Or this: http://www.google.com/search?sourceid=navclient&ie=UTF-8&rlz=1T4GGLL_en&; q=Windows+Mobile+trusted+SSL+ To verify, you can request a 'trial' certificate from Thawte.com (SSL 123 type) and deploy. This is a fully functional cert for 30 days that is accepted by all Windows Mobile devices without having to force the device to accept it and the authority. What is your OWA URL? good luck.

The Exchange server is front ended by ISA2006 SE. I have read and used the article "How to Publish Microsoft Exchange Active Sync with ISA Server 2006" by Marc Grote. The error that the mobile device gets is "The security certificate on the server is invalid. Support Code : 0x80072f0d". I have the OWA certificate installed on the Exchange and ISA servers since Sept 2007. OWA has been working fine since that time. I think my problem is related to SPN for HTTP/owa.all-mode.com. Should this be on the Exchange or ISA server? Any help is greatly appreciated.
