GAMMA, Pitney Bowes MapInfo partner in Ireland, are currrently testing our pre-release of Autoaddress for MapInfo.
There were a few technical challenges to overome when creating this .NET DLL integration, mainly around the single threaded nature of MapInfo Professional, versus the multithreaded nature of Autoaddress. These have now been solved, and the solution works as follows:
Step 1 - Open a table to Geocode in MapInfo
Step 2 - Choose Geocode with Autoaddress from the Tables Menu
The following dialog will appear

First you select your table and choose your address fields.
Then you choose how you want to update your table, either by simply creating points for the table, and/or updating columns in the table.
Step 3 - Click on OK
