I have Office 2010 x64 + W7 x64 + WDMC x64, I know what the OP means. When you connect the TP2 to your PC, part of the WDMC (Activesync connection?) is that it wants to sync your contacts and email's. There is a popup that shows up and says "Either these is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Office Outlook and set it as the default mail client."

If you are planning on NOT sync'ing your contacts and email's, (What I am currently doing) it works fine.

When connecting my phone just select on the WDMC screen the option to not setup a partnership.

Hope this helps.
