One month from today, we’re going to start to turn off basic auth for specific protocols in Exchange Online for customers who use them.

Since our first announcement nearly three years ago, we’ve seen millions of users move away from basic auth, and we’ve disabled it in millions of tenants to proactively protect them.

We’re not done yet though, and unfortunately usage isn’t yet at zero. Despite that, we will start to turn off basic auth for several protocols for tenants not previously disabled.

Starting October 1st, we will start to randomly select tenants and disable basic authentication access for MAPI, RPC, Offline Address Book (OAB), Exchange Web Services (EWS), POP, IMAP, Exchange ActiveSync (EAS), and Remote PowerShell. We will post a message to the Message Center 7 days prior, and we will post Service Health Dashboard notifications to each tenant on the day of the change.

We will not be disabling or changing any settings for SMTP AUTH…

Has there been any talk on how to push Outlook 2013 to use ModernAuth?

I am trying to deploy a batch file with PSexec but cannot get by some firewalls.

Easiest way is to set up the account again on the computer.
