Hello, thank you for reaching out to Microsoft Q&A.
Did you notice any unusual activity in your account? It’s possible that someone might be trying to access your account from a different location or from an untrusted device, which can trigger the “You’ve tried too many times” message when signing in.
First, sign in with your Microsoft account here to check for any unusual activity:
https://account.live.com/Activity
If you notice anything suspicious, we recommend that you change your Microsoft account password and enable two-step verification for added security.
1. Reset your Microsoft account password.
Open an InPrivate/Incognito browser window and use the following link to reset your password: https://account.live.com/ResetPassword.aspx
2. Sign out of your account from all sessions.
Once the password reset is successful, sign in with your account here: https://account.live.com/proofs/Manage
Scroll down until you find Sign out everywhere. Select Sign out everywhere.
3. Enable two-step verification.
On the Security settings page, under Additional security, turn on Two-step verification. Make sure you have at least three security verification methods active.
