[Leica] OT: Address book for both Windows or iOS

[Peter Klein]

Is there a way to keep one common address book which can be downloaded/updated to both Thunderbird on a PC and the iOS email client on an iPhone and iPad? Or am I going to have to go to a Web-based client and use that on all devices?

For years I've relied on my PC email client's "memory" of previously typed addresses, or   searched for the last email I received from someone. So I never bothered to keep a real address book for email. But now my emails are scattered between three devices, my paper address book is falling apart,  and I'm going to have to re-create it somewhere else anyway. So maybe it's time to unify things and join the 21st century.

I know I'm mixing matter and antimatter by using both iOS and Windows, but that's how things turned out, and it ain't gonna change for the foreseeable future. :-)

Thanks in advance!
