We have several users reporting an AADSTS165000 error when launching portal.office.com from their work computers. This issue is present for a portion of our users across multiple devices and browsers, Edge and Chrome. During testing we tried the following links as alternatives but they all produce the same issue.
https://portal.office.com?domain_hint=domain.com
https://office.com/login?domain_hint=domain.com
https://microsoft365.com/login?domain_hint=domain.com
Clearing the browser cache will allow the user to login once before returning to the same error on next launch.
Other links including Office.com and outlook.office.com are functioning as a workaround but this does not provide a permanent solution. We require a working link that allows the user to access the main O365 portal page without having to click the sign-in button on the main office.com site.
We experienced this issue for a few hours on Friday and thought it was resolved but it was reported again this afternoon.
Error is as follows;
