1. Download and install Gtasks from market on your Droidx
2. Purchase and install gsync it
http://www.daveswebsite.com/purchase_home.shtml only $15 well worth it.
3. Open Outlook, click Settings on the gsyncit toolbar, Select Task sync, click New,
Under Task Mapping tab: leave ssl checked, account type default, enter user name and password and click Verify account.
Very important: change the radio button from GoogleCalendar to Googletasks and in the drop down Google Tasks list select Mobile List. Under Outlook tasks select your outlook task folder. Under Sync options I choose Outlook tasks as my Primary. Everything else I left as default.
4. setup the rest of the syncs should you desire ( I recommend using only one sync program so if you using calendar sync uninstall that and use this.) Finally, make sure you click "Sync options" on the left list and setup the parameters, the settings are self explanatory so I won't go over them here. Now everything you type in Outlook Tasks will appear in Gtasks on your Droid!!
Final word of advice if you were using Calendar sync, I would do one last sync with that to make sure your outlook calendar is updated then delete the calendar on gmail that way when you setup a new calendar and sync with gsync it you won't have any weird duplicates or mismatched entries. Hope that helps.
