I have a new Windows Mobile 6.5 phone and I initially was able to sync with Outlook 2010. Now, however, it gives me the error 0X80072f7d.  I have researched this to discover that it has something to do with SSL certificates, but I do not understand that well enough to know what to do.  I need a simple step by step plan for correcting this problem so that I can sync my windows mobile 6.5 phone with Outlook, which is the whole reason I bought this particular for to begin with.

Was there any change on the server/PC side?

How do you connect? ActiveSync? Did you change the "Enhanced network function" for "USB to PC" connection setting on the device?

There are many posts in internet about this error code. One leads to http://www.winvistatips.com/fix-active-sync-error-0x80072f7d-mobile-6-1-andserver-exchange-2008-a-t809343.html

==========================================
"ERROR_INTERNET_SECURITY_CHANNEL_ERROR = 0x80072f7dExchange Sync requires SSL,
ERROR_INTERNET_SECURITY_CHANNEL_ERROR = 0x80072f7

Exchange Sync requires SSL, you will need to verify that the trusted root
cert is installed on the device

This might be note worth

"Windows CE-based devices do not recognize IIS server certificates signed by
using either the MD4 or RSA/SHA1 signature algorithms and rejects
certificates with the error: "ERROR_INTERNET_SECURITY_CHANNEL_ERROR". To be
acceptable to a Windows CE-based device, an IIS server certificate must be
signed using either the MD2 or MD5 signature algorithm.""
...
"Turns out that Windows Mobile 6.1 (or earlier) can not handle SSL certificates greater than 4096 bits.
Once I re-keyed the SSL certificate to be 4096 bits the problem went away."
