I have been using Outlook 365 for over a year now but in the last month or 2, I have had several clients telling me their emails to me are being bounced back. After doing some digging and analyzing, I determined when the recipient replies to my email, the "reply to" address is filling in incorrectly. My actual email address would be aperson@df.,com, but the reply to address being filled in and the address they are subsequently sending to is firstname.lastname@example.org. How can I change this? I am concerned about all the replies I am not getting. This does not seem to affect all, but the list of clients and vendors it is affecting is growing. I need to find where that setting is incorrect and change it.
Emails sent directly to the correct email address are not affected.
