Email Authentication Process


To avoid interruption in Streamline for incoming emails using Office 365, you must login to your Microsoft account and follow instructions below.

*Instructions are directly from Microsoft website

Option 1: Request to opt out of Basic Auth being disabled (Must be done by 10/1/22)

To invoke the self-service diagnostic, you can go directly to the basic auth self-help diagnostic by simply clicking on this button (it’ll bring up the diagnostic in the Microsoft 365 admin center if you’re a tenant Global Admin):

Or you can open the Microsoft 365 admin center and click the green Help & support button in the lower right-hand corner of the screen.

When you click the button, you enter our self-help system. Here you can enter the phrase “Diag: Enable Basic Auth in EXO

Customers with tenants in the Government Community Cloud (GCC) are unable to use the self-service diagnostic covered here. Those tenants may opt out by following the process contained in the Message Center post sent to their tenant today. If GCC customers need to re-enable a protocol following the Oct 1st deadline they will need to open a support ticket.

Opting Out

During the month of September 2022, the diagnostic will offer only the option to opt-out. By submitting your opt-out request during September, you are telling us that you do not want us to disable basic for a protocol or protocols during October.  Please understand we will be disabling basic auth for all tenants permanently in January 2023, regardless of their opt-out status.

The diagnostic will show a version of the dialog below, and you can re-run it for multiple protocols. It might look a bit different if some protocols have already been disabled. Note too that protocols are not removed from the list as you opt-out but rest assured (unless you receive an error) we will receive the request.

Update 9/28/2022: Every customer who has opted out so far, can now see a Message Center post if we have received their opt-outs (MC437540). We expect to send out several more MC posts for customers who opt out before end of September, last one during the weekend when opt-out phase ends.

Option 2: Re-Enabling Basic for protocols (Can only be done after Oct 1st, 2022)

During the month of September, the diagnostic can not be used to re-enable basic auth (it is in opt-out only mode).

Starting October 1, the diagnostic will only allow you to re-enable basic auth for a protocol that it was disabled for.

If you did not opt-out during September, and we disabled basic for a protocol you later realize you need, you can use this to re-enable it.

Within an hour (usually much sooner) after you run the diagnostics and ask us to re-enable basic for a protocol, basic auth will start to work again.
