How can I disable auto capitalize function in web Outlook with missing "editor" button?

It seems like 3 month ago suddenly when I compose a letter the auto capitalize function started to active and can't turn it off since there is no editor function which is mentioned years back over the internet. Spell check and correction functions are disable everywhere (checked), not on in windows, not on in edge, not on in word, nowhere. So how can I disable that silly function? It gives me false corrections since my language isn't english and I don't need to have a lot of word with capital letters, so irritating.

Oh and it's a working account, I asked the IT leader and there is no company setting for this.

Hello @Hasilló György,

Thank you for the information you shared.

I’ve done some testing in my Outlook web environment, and I was able to successfully disable both auto‑capitalization and spell check/correction by following the steps below:

When composing a new email or replying to an existing one, please click on the “Editor” icon on the ribbon, then select “Editor settings.”

In the panel that appears, you can toggle all the options off (as shown in the screenshot above), including auto capitalization and correction features.

After turning these off, the email should no longer automatically capitalize text or apply spell checking.

If you do not see the Editor icon, please try clicking the arrow on the right side of the ribbon to expand or switch the layout, which should reveal additional options, including the Editor icon.

Could you please try these steps on your side and let me know if it works for you?

Kind regards,
