Microsoft has fixed a known issue causing desktop and mobile email clients to fail to connect when using Outlook.com accounts.
More details on how to use app passwords with apps without two-step verification support can be found in this support document.
Customers affected by these sign-in problems started sharing reports on Microsoft's community platforms and other social networks like Reddit last Tuesday.
Even for those who entered the correct credentials, the login window would still pop up as the app tried connecting to the Outlook.com account.
Outlook.com users have been experiencing other issues in recent months that have prevented them from searching for email content or caused their email clients to crash.
Two months ago, the Outlook team fixed another known issue that caused Outlook Desktop clients to crash while sending emails from Outlook.com accounts in Version 2311 Build 17029.
Redmond also resolved an issue in July that was causing 401 exception errors for Outlook.com users and breaking email searches.
In June, multiple Microsoft services, including Outlook.com, OneDrive, and the Azure Portal, were disrupted by DDoS attacks later claimed by a threat actor known as Anonymous Sudan, believed to have Russian links.
