Using Classic Outlook on Windows for personal email, calendar, and contact management
Playing around with this formula and works great, but when I added it to my view it showed another workaround.
The external tag only shows if the build in "From" column is the first "text" based field.
I swapped the received column in front of "From" and the label disappears.
Tried a few others like mention, categories, auto forwarded, read etc but that did not work.
Had to be a "text" field like received, subject, sensitivity, size.
