Users of some versions of Outlook have been cut off from Microsoft 365 service
Several versions of Microsoft's Outlook email client will soon be unable to connect to Microsoft 365 services, the company has warned.
In a recent blog post, Microsoft said that in less than two months, users of Outlook 2007, 2010 and, to some extent, Office 2013 (versions earlier 15.0.4971.1000) will lose the ability to connect to Microsoft 365 services.
The company has invited its users to upgrade to the new versions ahead of time to avoid disruption. Microsoft said its support team is reaching out to people still using Outlook 2007 and 2010 to "help them meet the deadline," and said anyone who can't handle it on their own should seek help.
Explaining what the move means, Microsoft said that as of Nov. 1, older versions of Outlook will no longer support basic authentication (which the company says should improve Microsoft 365 security).
