Clicking that message produces a brief screen flash and then nothing, meaning no data entry popup in which the password could be re-entered. The message is, 'Need Password' in a very small icon at the bottom of the mail frame. I have not encountered a problem quite like this in several decades of working with Outlook. I have tried too many solutions to recount here but one that may be relevant is that I did a full online repair of Office Pro 2021 with no change in behavior. The web 365 version of Outlook works well also. At the very same time, I can send and receive test email on all of the several devices I mentioned above using the same email addresses and passwords. It may not make any difference, however, because one of the configuration options sends me to a browser and my Microsoft account, where the same thing happens: Even online via a browser, Microsoft indicates that it cannot find the email address or the password is wrong. (Problems like keyboard and password errors have been checked and triple-checked.) Outlook appears to be connected to the Internet (as the entire laptop is) but I can't authenticate that it is. When I attempt to edit or add one of the working email accounts (only three were configured on the source image) the Outlook wizard searches for a long time, and finally indicates that the account cannot be found. A small message at the bottom says, 'Password Needed' but when clicked, the screen flashes briefly and nothing happens.

Email messages (received and sent) up to the date of the image are showing but Outlook will not retrieve new email.

Other than Outlook, everything works perfectly and the image saved me many hours of configuring software. This week, I prepared a new laptop and installed an image of the existing working laptop (same make and model) and updated the licenses for Windows, office, and other software.

These accounts and email clients have been working well for more than two years. I access these accounts on a Windows 11 desktop running Outlook and Office Pro 2021, an iPhone, an iPad, and one laptop running Windows 11 and Office Pro 2021. I have five email accounts hosted by Microsoft on Exchange.
