Question

Why is sign-in to personal email account required every month?

Courtney Brinson 0

Every month, usually towards the first of the month, my wife and I are both required to re-sign into our personal email accounts in order to gain access our accounts and our email messages. Why is this required every month? Can Microsoft prevent this from occurring by accepting/certifying both my and my wife's sign-in to our accounts permanently? I continue to pay Microsoft for my account so why are we required to sign-into our accounts every month?

The regular sign-ins could be a requirement from the e-mail services. Are you using any third-party (non-Microsoft) e-mail addresses, such as @gmail.com?

Hi, I understand why this is frustrating. A paid Microsoft 365 subscription doesn’t guarantee permanent sign-in; Microsoft may still request identity verification for security. However, that doesn’t establish why both accounts are being signed out every month.

Are you both using the Outlook app on Windows, or accessing email through a web browser? What exactly does the sign-in message say?

If you use a browser, check whether it or a cleanup tool automatically deletes cookies. Deleting cookies can remove your saved sign-in session.

I am using the Outlook app with Windows 11. Each month, it just restricts my access to Outlook and requires that my wife and I sign-in to our email accounts to use them. I can’t remember the exact wording of the message, but all of our Outlook folders are hidden and unavailable until a sign-in is made and accepted.
