=HYPERLINK("mailto:" & TEXTJOIN(",", TRUE, M1:M32), "Email All") this formula is not working unless I make the range to "M1:M10" Why? Im trying to combine 32 email addresses into one hyperlink that would email all at once with one click and open Outlook.
Restarted excel. Tried a new blank document. Nothing worked.
=LEN(TEXTJOIN(",", TRUE, M1:M32)) + LEN("mailto:")
