Thanks again Gary.
I dont think that this Extra Feature is for “smaller or greater user mistakes”, but of course, in this cases it helps also.
If i’m right, this should specially used by users, who are new and have used the great “Import & Migrate Feature”.
Maybe a mistake from me, not to tell you this detail.
In front of this, for all new users who have multiple archives and plan to migrate/import all to eM Client. on my perspective: Clean Up your Mails before you migrate to eM Client, and dont plan to use the “Deduplication” Extra Feature because it could end in more work then before.
All other features are worth, u will love it (especially the gmail integration is awesome) so try it
