Language detection

Hey everyone,

I have the following problem in Outlook, and I was wondering if there is a solution for it.

I write my E-mails mostly in Dutch. However even though I deleted my language check in German and English, everytime I write an E-mail it automatically sets the language to English. Not only does wrongly check my spelling. The autocorrect option also changes my words even though I write them correctly.

I would like it if I can let outlook autodetect wheter im typing Dutch, German or English. However, so far I have had no succes and I feel like tried everything. Is anyone able to help me with this?

Thanks in advance.
