Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi D Ramdeen,
I noticed that you ticked the Preserve Favorites website data option when clearing the browser history. Please try to uncheck that option, in case the Office 365 Portal is included as your Favorites.
Additionally, we'd like to collect your account information to check your authentication type. If your organization uses a federated domain, it might be configured to automatically sign you in using your Windows user account, which is usually the same as your Office 365 account.
In this case, Office 365 will directly skip the password and authenticate using the domain account.
We will send you a private message to collect the account info, and we would like to get a video as well to confirm the behavior.
Regards,
Sheen
