Use auto archive on two client

I successfully auto archived my email history to my desktop PC.
Now I’d like to “copy” this archive to my laptop in order to have the history at hand.
Alas simply copying /appdata/roaming/emclient/archive seems not to work.

Any clue on how I could have the archive on two machines (licensed of course)?

Unfortunately you can’t copy parts of a database in Explorer and add it to another. It won’t work, and may even break the target database. Then you will need to delete the database and start again.

You can export the folders on one device (Menu > File > Export > Email) and import it on another (Menu > File > Import > Email), but pretty soon you are going to have duplicated data on the target unless you delete the old imported data completely before you import the next time.
