How to delete old email account from outlook app

We have customers who cant login in the Outlook App. The Outlook App sho: "Incorrect configuration warning: Your organization's support team would like you to log in with this account: old M365 account. However, you have tried to log in with the current M365 account."

Point 1:

It would be nice if this option exist. Some Customers have the problem after an iOS Update, the outlook App is disconnected and they must Sign-In again. The Outlook App cancel this action with the comment that the users ar already logged in with an old TenantID and want to connect with the actual Account. But before the iOS-Update, they used the Outlook App with the actual account.

Even if you delete all Microsoft apps from the iPhone, Outlook still thinks that there is an old login. Auch der über den Edge-Browser edge://signin-internals in Edge iOS and click RemoveAllAccounts wont remove the old Microsoft login. So there always seems to be a residual Microsoft login on the device.

What other way is there to completely remove the Outlook logins on the iPhone if you are not logged into the Outlook app (as this is not possible at the time)?

Please add a reset point, which is accessible from the iPhone settings, as it is available for the Teams app (Setting -> Apps -> Teams -> Delete App Data).

The only workaround which worked is to reset to factory the iPhone. However, this cannot be offered to any customer, as it is obviously a remnant of the Microsoft login.

Kind regards.

Thanks Eleni, however, none of these options are available to me. 1) "Reset account settings" doesn't exist on my iphone (I have a 15 pro max). 2) Tried this already, doesn't fix the issue. 3) there is no "passwords & accounts" option
