how to disable "auto-capitalize first letter of sentence" on OUTLOOK.COM email please?

This problem started happening months ago, and outlook.com still hasn't fixed it. Somehow it's attempting to capitalize the first letter of what it thinks is a sentence, whenever I'm composing a new message (or replying to an email). MS lets us disable this "feature" in the Outlook program/app itself, and also in Office products too (MS Word, etc). But why not on Outlook.com? This is the kind of cluster I have to manually correct while typing, every single day.

P.s. Ask mom's Dr. To bring the red, pink, orange, etc. Colored pills to the HR dept. Tomorrow night. Also the L-train i.e. Subway isn't working until Jan. Of 2026

Every one of the 7 bolded characters above should of course NOT be capitalized, but yet outlook.com does, and never stops! All the time! With no way to turn it off! Please someone tell me how to stop this madness?

Thanks Mike for at least helping me find the switch. For me, this still does not work, Outlook simply ignores the setting and will auto capitalize every time I press enter to go to a new line. Even when composing a message. This still occurs even when I turn off auto-correct. There was a temporary fix that I found that required you to write everything in plaintext, but since that also killed all formatting (including company email signatures) this was not worth the effort.

I for the life of me cannot understand why Microsoft has decided to not fix this issue. It has been persistent at my company for more than a year now and I can honestly say that this leads to at least 30% more time and 300% more frustration when composing a simple email. Old Outlook was much, much better.

Update! I actually found an answer to this question myself, with help from MS outlook chat. Which did take quite awhile, but I'm posting the solution here, in case anyone else in the future stumbles across this technical support problem.

When you're composing a new email message (or a reply) you should see a white-background horizontal row near the top of your screen, with words like: Delete, Archive, Report, Sweep, Move To, Reply, etc. Near the far-right end of that row is a teeny tiny down error. Click on this upside-down triangle looking icon, and after several seconds, this white row of options should expand to be 2-3x the height that it was. Or maybe if you happen to keep this toolbar expanded all the time, if that's your personal preference, skip that whole last part.

You must click on the word "Message" in this top row, then click on the word "Editor" at the far right-hand side. Click on "Editor Settings" and there's a choice there for "Enable Auto Capitalization" which you should turn OFF. Note that you must do this while you're composing a message (or reply) - none of this will work if you're just viewing some random email message in a folder. Why in the world MS chose to bury this important toggle-switch here, instead of in the more conventional main "SETTINGS" choice is beyond me. But after months of struggling with this, I'm grateful to have found the solution.

Thank you, thank you for the answer! Even the built-in help system couldn't even point me to any setting with the word "capitalize" or "capitalization". Ugh....

Hi,

I don´t know whether this is a localization problem, but I have found both "Editor settings" in Top ribbon "properties" (there is one on the left and one on the right :) ... yeah). In the 1st one I have disabled everything related to uppercase. I have also disabled autocorrect altogether. In the second one I have not found the setting mentioned. Neither solved the issue.

Something went completely wrong in microsoft in the past few years. Mabe they have fired all the people with a brain and left unpaid highschoolers with Chatbot to develope their software ... That is my guess.
