Recovering OneDrive account that still receives "Your memories from this day" emails

Yes, but it depends on the account state.

• If the Microsoft account was closed by choice, it can only be reopened during its 30-day or 60-day grace period by signing in at https://account.microsoft.com and completing the security code check. After that, it cannot be reopened.
• If the account has been inactive for more than two years, it may have been automatically deleted, and it can no longer be reopened.
• If OneDrive says the account is frozen, sign in with the correct account credentials. A common cause is having a different Microsoft account than expected.
• If the email address is not recognized, try account recovery and verify that the correct email domain and alias are being used. If the username still is not found, contact support through the Microsoft account support flow.
• If the account was temporarily blocked, it may be due to suspicious activity, large traffic volume, or a policy violation. In that case, use the Microsoft services account reset page. If the account was recently verified by text message or many files were shared, the block can be removed within 24 hours.
• Receiving “Your memories from this day” emails does not by itself confirm that the account is still recoverable. Microsoft notes that genuine OneDrive emails can come from @mail.onedrive.com, @notificationmail.microsoft.com, or @infomail.microsoft.com.

Practical path:

1. Try signing in at https://account.microsoft.com with the same address.
2. If the address is not recognized, check for a different alias or country-specific domain such as .com vs .co.uk.
3. Use the account recovery process if the password or username no longer works.
4. If the account was closed, reopen it only if still within the grace period.
5. If OneDrive reports the account is blocked, use the account reset page.
6. If the account has already been deleted, recovery is not possible.
