Hi Bob,
when Groups.IO sends a message to the email addresses of the group members, the ?from¡° address is the email address of the group, not the address of the sender (look at the address in Outlook!). So a regular email program, when you reply, sends it to that address i.E. the group¡®s address, and all members receive the response. An email program like Outlook doesn¡®t see the original sender¡®s address, so it can¡®t reply to just that address.
The Groups.io web site or app offer a special handling when replying, giving the option of replying to the individual sender instead of the group.?
Kind regards
Thomas
