Hi @Ethan Strauss ,
Welcome to our forum!
In order to verify your issue, has this problem occurred recently, or has it always existed?
We suggest you also check the “Mark grammar errors as you type” check box to disable the grammar check
Try to create a new profile and re-add your account to test if the issue continues. To create a new profile, follow the steps:
Go to Control Panel > Mail > Shows Profiles > Add, then re-add your account.
If the above doesn't help, it could be due to registry corruption, and you need to repair office from control Panel
Hope above can help you! If you still need help, feel free to contact us.
