Before you start

Gather any alternative verification details you may have set up, such as a linked phone number, and ensure you are using a familiar device and internet network you frequently use to sign in.

Solution 1Recommended

Use an Alternative Verification Method

Use this method if you have previously linked a phone number or authenticator app to your Microsoft account.

Initiate the sign-in process

Go to the Microsoft account sign-in page and enter your account credentials as usual.

Select an alternative method

When prompted to verify your identity via the old email, select 'I don't have these any more' or directly choose an alternative verification option, such as a text message to your linked phone number.

Complete verification

Follow the on-screen prompts to enter the code received on your phone or authenticator app to access your account.

Update security settings

Once logged in, navigate to 'Security' and select 'Advanced security options'. From there, add your new security email address and remove the inaccessible one.

Frequently Asked Questions

Can Microsoft Support bypass the 30-day security information waiting period?

No. The 30-day waiting period is an automated security measure designed to protect your account from unauthorized takeovers. Microsoft Support agents do not have the system permissions to bypass, cancel, or shorten this mandatory timeframe.

What can I access during the 30-day waiting period?

During the 30-day wait, you can still use your Microsoft account to access basic services like Outlook, Skype, and OneDrive on devices you have previously signed into. However, you will be blocked from accessing sensitive account settings or making financial transactions until the period is over.

Why does the account recovery form (ACSR) get rejected?

The automated system may reject your form if the information provided is insufficient or does not match historical account data. To improve your chances, submit the form from a recognized device (like your home PC), use your regular internet connection, and answer as many questions as possible with exact details.
