I am using OE 6 and Win XP Pro

I click on Addresses Icon on the menu and go to Tools. There is a feature
called Synchronize Now. I am not sure what this Synchronize feature is
supposed to be doing. I tried going to Help, but when I typed Synchronize
in the search box I get a response saying No Topic.

Could someone please explain what this feature does so that I can decide
whether I want to use it

Thanks
