Can't login into my Microsoft account, it says that my account has been deleted anyone can...

Currently I haven't tried any due to the fact I did not have the time to do so.

Are you able to sign in with your account here or not?
https://account.microsoft.com/profile

If yes, what troubleshooting steps you have done so far to fix this problem?
In that way I can advise you different things or how to proceed

Thanks for the update. Please try when possible do all the solutions provided above

If that doesn't work and If you have important proof of ownership for that account (emails, important screenshots, etc)
You can try opening a 1:1 chat with Microsoft support and explain them the situation

If you're not able to prove your ownership, unfortunately you may need to create a new account

Hi Nicolas,

When was the last time you successfully signed in to your account? As explained in the Microsoft account activity policy, any Microsoft account that hasn’t been accessed for 2 years will be closed/deleted (with a few exceptions).

There’s unfortunately no possible way to recover your account once it’s been automatically deleted because of inactivity.

Hope this helps.

You're welcome!
Feel free to share the resolution when possible
Take care in the meantime Nicolas
