We want to enable external sender identification on our EXOL environment (based on https://learn.microsoft.com/en-us/powershell/module/exchange/set-externalinoutlook?view=exchange-ps).
However we have noticed something in our test environment that stops us from deploying it further in our organization:
We have enabled external sender identification on our test environment and it seems that the external e-mail tag in Dutch lacks a verb: "email address removed for privacy reasons van buiten uw organisatie" .
A suggestion for a translation:
The French version is « Cet expéditeur … provient de l’extérieur de votre organisation » ;
The English version is « This sender … is from outside your organization;”
So for the Dutch version I would suggest “Deze afzender … is van buiten uw organisatie” .
