Fix Microsoft Account Not Recognized After Accepting Family Invitation
Question details
The user receives a 'Microsoft account does not exist' error when trying to accept a Microsoft 365 Family invitation via email, even though they can successfully sign in to account.microsoft.com.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Accepting a Microsoft 365 Family invitation sent via email.
- Observed behavior
- The system displays a 'That Microsoft account does not exist' error message instead of linking the account to the family subscription.
Ensure you are completely signed out of any other Microsoft accounts on your browser, or open a private/incognito window to prevent account conflicts before clicking the invitation link.
Verify and Use an Account Alias or Mobile Number
This error often occurs because the email address the invitation was sent to is not set as the primary alias for the Microsoft account. Updating your alias settings can resolve the issue.
Microsoft accounts can have multiple aliases (email addresses or phone numbers) tied to the same inbox and subscription data. If the invite was sent to a secondary alias or an unrecognized address format, the system may fail to register the acceptance.
Go to account.microsoft.com and sign in with your known credentials to confirm your account is active.
Navigate to 'Your info' and select 'Edit account info' or go directly to https://go.microsoft.com/fwlink/?LinkId=529489 to manage how you sign in to Microsoft.
Add a new alias (such as an Outlook.com address or your mobile number) or verify that the email address the invitation was sent to is listed. Set the preferred alias as primary if necessary.
Open the email invitation again and try to accept it using the verified primary alias or mobile number.
Request the Organizer to Resend the Invitation
Invitations can expire or become corrupted if previously clicked while signed into a different account.

Frequently Asked Questions
Why does Microsoft say my account doesn't exist when I can sign in?
This usually happens if the email address you received the invitation on is not set as the primary alias for your Microsoft account, or if there is a temporary sync issue between the invitation system and Microsoft's login servers.
Do Microsoft 365 Family invitations expire?
Yes, Microsoft 365 Family invitations sent via email can expire. If an invitation is older than a few days or has been clicked previously under a different account session, ask the subscription owner to cancel it and issue a new one.
Can I use a mobile number to accept the Family subscription invitation?
Yes. If your mobile number is properly linked and verified as an alias to your Microsoft account, you can use it to sign in and accept the Microsoft 365 Family invitation without using an email address.
