Configuring preferences and options in Outlook.com
THANK YOU! It did not work for me at first, then I modified the formula and it worked. Here are my steps (ALL credit to Jeffrey on this!) that worked in the Outlook desktop app installed on Windows 11:
HOW TO CODE MS OUTLOOK (DESKTOP) TO DISPLAY THE TRUE EMAIL ADDRESS IN THE LEFT COLUMN INSTEAD OF THE "FRIENDLY NAME"
Ribbon
View Settings
View Tab
Columns
New Column…
Name: From address
Type: Formula
IIf(Left([SearchFromEmail],2)="/O",[FROM]+"","<"+[SearchFromEmail]+">"+" ("+[From]+")")
Under "Select available columns from:", select user-defined fields
Move the new "From address" "column" to immediately above "From"
Click on "From" and remove it
OK
OK
