Hi Sindee,
I'm truly sorry to hear that you're experiencing this situation.
To better understand the issue and help you look into it, could you please share more details:
- Is this a work/school Exchange email account or a personal Microsoft email account?
- When you try to add the account again, do you receive an error message? If so, what does it say?
- Are you unable to sign in to the account entirely, or can you sign in through a web browser but not through the Apple Mail app?
- When you say you cannot recover the account, do you mean the account itself is inaccessible, or that your previous emails and folders are missing?
I greatly appreciate your cooperation and understanding. Hope to hear from you soon.
