is there a way to merge duplicate contacts?
You would initially use the eM Client Deduplicator option via “Menu / Tools / Deduplicator” and select “Contact” to initally search and bring up the contact duplicates.
Then see Garys post below from the following thread on merging multiple exiting contacts.
@Gary post extract below from the above thread.
“It requires searching the entire address book, but you can select which contacts to ignore if you only want to merge a custom selection”.
