Server migration is a very stressful task. It involves moving business-critical data between different locations. Since the extended official support for Exchange 2013 ended on April 11, 2023, the number of companies which are looking into migration away from it might be on the rise. While there is more than one possible target server to migrate to, Exchange 2013 to Microsoft 365 migration seems to be one of the most popular scenarios. In this article, I’ll show you what the available methods are to migrate from Exchange 2013 and how to approach them.
fr-BE doesn’t work either -> it turns out to be the same as nl-NL (Nederlands and not french) !

Hi Marc, thanks for the info. It seems Microsoft might have changed the language IDs or the number of languages available in Microsoft 365. I’ll look into it and update the article.
Italian should be “it-it”, not just “it”.
And Swiss-German doesn’t work anymore.
dansk (Danmark) should be da-dk and not da
Thanks for sharing.
I have to add that the languages with two letters are not working for me, e.g. ‘de-li’ is working, ‘de’ is not.
You can always try the de-de format in such situations.
I like this list because it helped me to found out the initials of languages to istall the word office 19
