Starting November 1st, 2021, only Outlook 2013 SP1 (build 15.0.4971.1 and greater) will be able to connect to Microsoft 365 services. This means older Outlook 2013 builds, and Outlook 2010 and earlier will not connect to Microsoft 365. This new requirement goes hand in hand with the deprecation of basic auth, requiring Outlook 2013 SP1 (build 15.0.4753.1 and greater). Microsoft is deprecating basic auth on October 1st, 2022.
That said, if you are already blocking legacy auth for Outlook clients (or you are reading this post after October 1st, 2022), you may receive the following error when trying to sign in to your Office 365 account with Outlook 2013 or any other Office suite product. In addition, your Outlook 2013 client might not be able to connect to your Office 365 mailbox either.
When signing in to your Office 365 account via File > Office Account > Sign In from any Office suite product, you receive the following error.
Your account is in a bad state. Please sign-in to this account online to address the issue.
Alternatively, you may first see the error below which can then lead to the error above when you click the Fix me button.
