ActiveSync error 0x80072F17 - 13.Sep.2007 1:21:47 AM

HI Guys,

Ive recently installed Exchange 2007, and all that i have setup so far has been working fine including OWA.

The main reason for the upgrade was to begin to ustilise the wireless email functionality between exchange and some PDA's that senior management would like to use when they travel overseas.

I am testing one PDA, the internet connection is working but when i try to sync i receive the error 0x80072F17, which i have found is something to do with not havinga trusted certifcate in IIS on the server.

When i check IIS the certificate that was installed with exchange says "The CA root certificate is not trusted. To Enable trust, install the certifcate in the Trusted Root Certification Authorities store.:

Firstly, how do i install that,

And secondly, do i need a 3rd party certificate, from say thawte, to enable the direct oush to work between the PDA and Exchange.

Is there anything else i need to setup on the server?

Thanks in advance

I had struggled with the same problem for about 2 weeks before giving up and contacting the powers to be.
Are you using windows mobile 5 devices? Mobile 5 and some phones with mobile 6 are NOT compatible with exchange 2007 yet.  The new Motorola Q, the treo 700w/wx, xv6700 etc to name a few are not for use with exchange 2007.
Your error IS an ssl error, however after contacting palm, verizon, usstarcom, and others, that is the answer I received.  Check your mobile versions.

Mobile 5 and Mobile 6 work just fine with Exchange Server 2007.  You need Mobile 6 to acheive all the features that Exchange Server 2007 provides.

Yes, you will want to use a third party certificate.  I would make sure you get one that signs their certificate using the root server.  For instance, Verisign signs their new SSL certificates using their Intermediate Server.  Because Mobile devices do not support certificiate chaining, you will have to install the intermediate certificate on each device still.

So there are a few things you can do.
1. Get a third party certificate which is already trusted by your mobile devices
2. Get a third party certificate which is already trusted by your mobile devices which is signed by an intermediate store which means you will have to still install the intermediate certificate on mobile devices
3. Use your own certificate, but import the root certificate into the root certificate store on all your mobile devices.

Also, when you enter your credentials in Activesync, make sure you put the netbios name of your domain, not the FQDN.  I'm not sure if this is the case with all mobile devices, but when I connect my Palm Treo 700w to Exchange 2007 Server, if I put in the FQDN of my domain, it will give me an Active Sync error.  But when I put in the NetBios name, it'll sync up just fine.

Hope that helps.
