Microsoft has fixed an issue causing some Microsoft 365 users' Outlook desktop clients to stop connecting to email servers via Exchange ActiveSync.
Exchange ActiveSync is a synchronization protocol used by Microsoft Exchange to allow users to access their email, calendar, contacts, and tasks.
The known issue only impacts Outlook for Microsoft 365 users who have updated their clients to Version 2401 Build 17231.
Last month, Microsoft fixed another known Outlook issue, which caused connection problems for desktop and mobile email clients using Outlook.com accounts.
