I am having the same issue, but the above options are not present for me on my student outlook mail which I am unfortunately required to use. My options when clicking the 3 dots are:
- Save draft
- Insert Signature
- Show Form
- Set Importance >
- Show message options...
- Switch to plain text
- Check for accessibility issues
None of which apply to this situation.
I found the setting buried really deep in settings.
Click the gear icon in the upper right of the screen to open quick settings. Then scroll to the bottom and click "view all outlook settings" and then go to "Compose and reply". There is an option here to disable spell check (which is also redundant, since
my browser has one with my own custom dictionary of added words) and to disable the more annoying features like "Quick suggestions", "suggested replies" and "text predictions", but to disable this particular annoying feature you then have to click "Microsoft
Editor settings" and then you have to manually click each and every stupid little correction and refinement check you want disabled.
Of course, despite turning off all spell checks, it STILL won't shut up about my own name being a misspelled word. It also continues to show suggestions for what other people send to me despite having turned it off on my end, so if the other person hasn't
turned it off it will continue to nag me. For example, my professor said in an email:
"Please get started making arrangements for next week as listed above" and it underlines "making arrangements" and suggested "Try using a verb instead of a noun phrase to be more concise" and then suggests "deciding" and "planning" which makes no sense in the
context of the meaning behind the words. This exemplifies just how bad this feature is. The suggestions are dumb and there is no good way to fully get rid of.
Really, I would NEVER voluntarily use Outlook if I wasn't required to for school.
