ActiveSync 0x85010014 over the air

Hi gang,

I've got a client, who is using a Verizon mobile phone running Windows Mobile 6 on it.   We set it up so that he could connect to the Exchange Server over the air.   The server is a Windows 2003 SBS machine running Exchange 2003.  

Everything was working perfectly.   Until he decided he wanted to back up his files onto his PC.   So when he connected the PC USB Cable, he set up a second sync source (the PC).  

Now when he tries to ActiveSync over the air, we get an error code: 0x85010014

We tried deleting both sync sources and recreating the Exchange sync, but it didn't fix the problem.
We took it down to Verizon and tried a hard reset of the phone, but again it didn't fix the problem.  Verizon even tried configuring some brand new phones, but it didn't work, so they are saying the problem is on our end. But our end WAS working, so I don't really think it's a problem with the Exchange Server.

Anyone got any ideas?   It's really frustrating him.

/Exchange has SSL required in IIS?

I tried it both ways, with required SSL turned on, and then tried turning it off.  It didn't work either way.   So I turned it back on again.
It can't be on.  It won't work, unless you do a series of registry hacks and creating a NON-SSL version.

Follow this, then look at the event log for errors when you try an dsync.

Yes, but it didn't work when I turned it off either.

Plus the sync was working before.

Double check your server settings against this document from alanhardisty:

there is no need to make any registry changes to make this work.

If your using a self signed SSL certificate then you will run in to problems. have some great offers on SSL certificates at the moment.

If you don't have an SSL Certificate and you turn SSL on then it won't work!

MS KB 817379
0x85010014 is HTTP 500 error message if we check the IIS logs.

To further isolate the issue, could you try and create a new profile for Exchange ActiveSync on the Mobile Device for another user (new user mayb) and check if the same code is returned.

You can also run a ActiveSync test at and let us know the results.

Let us know how it goes.

It did turn out to be KB817379.
Which really makes no sense, because it WAS working about 2 months ago.   I have no idea what changed, but after going through the KB again, it started working again.  So I'm confused.  But as long as it's working I'm fine...

Thanks Guys.
