Microsoft is investigating an issue that prevents Outlook and other email clients from connecting when using an Outlook.com account.
"Since starting around 1/23/24 users have reported issues connecting with Outlook 2013, Outlook 2016, Outlook for Microsoft 365, Thunderbird, and mobile email apps when connecting with POP, IMAP, and Exchange connections," Microsoft says.
In December, the company fixed another issue, causing Outlook Desktop clients to crash when sending emails from Outlook.com accounts in Version 2311 Build 17029.
