The second reason has a bit more background, and I recommend reading up. Now, many of the Microsoft pages I link to above, feature PowerShell scripts to change that behavior, but it’s actually an option box in the Microsoft 365 admin portal, these days.

My tip for today is to check your tenant’s Modern Authentication settings, before migrating from Office 2010 Professional Plus, or Office 2013 Professional Plus installations without the specific registry settings.įor tenants created before August 1, 2017, modern authentication is turned off, by default. Wouldn’t it be sad if you had to touch people’s Outlook profiles twice within the next six months? Because, that’s the direction I think a lot of early adopters of Office 365 are heading. If you are a large enterprise that runs Office 2010 Professional Plus throughout your organization, then upgrading to a more recent version of Office should be high on your priority list. Several situations might create some urgency. However, these changes do not mean that as an organization you can just lean back. “We’ll cross that bridge when we get there”-people are onboarded more easily that way, is my experience. Politically, I’ve used this trick a couple of times at customers to reduce resistance to less popular changes, just to get a ‘go’. The timelines above stem from the support lifecycles, service level agreements Microsoft offers and the corporate responsibility guidelines that Microsoft follows. These announcements do not affect SMTP AUTH and Microsoft continues to support Basic Authentication for it in Exchange Online.

This version of the Office suite features the last version of Outlook that doesn’t support Modern Authentication.
