|Announced on||Removal on|
September 20, 2019
October 1, 2022
To improve security across their product APIs, Microsoft announced on September 20, 2019 that it planned to stop support for basic authentication (transmission of the username and password combination) on all Microsoft APIs. The deprecation of basic authentication will also prevent the use of app passwords with apps that don't support two-step verification.
Microsoft has already enabled OAuth 2.0 (the industry-standard protocol for authorization) on all of their APIs.
This announcement answers the following questions:
- When will Microsoft stop support for basic authentication?
- How is Zendesk Sell affected?
- What do Zendesk Sell customers need to do?
- Where can I find more information?
When will Microsoft stop support for Basic Authentication?
Microsoft begins ceasing support for basic authentication October 1, 2022. You can no longer use basic authentication in Exchange Online for any of the following:
- Exchange ActiveSync (EAS)
- Remote PowerShell
- Exchange Web Services (EWS)
- Offline Address Book (OAB)
- Outlook for Windows and Mac
- SMTP AUTH will also be disabled on all accounts that are not using it.
For more information, see the Microsoft technical support documentation.
How is Zendesk Sell affected?
The following three integrations in Sell that currently use basic authentication are impacted by this change.
- Microsoft 365 email integration
How is my email integration affected?
We will ask about the re-authorize of the Microsoft account. If your account uses basic authentication, you’ll see a dedicated button in your Communication Center that will ask you to re-authorize your existing integration from basic to modern authentication.
- Microsoft 365 calendar integration
How is my calendar integration affected?
As of August 31, 2022, Zendesk Sell no longer supports basic authentication for the Microsoft 365 calendar.
- Microsoft 365 contacts integration
How is my contact integration affected?
As of August 31, 2022, Zendesk Sell no longer supports the integration of Microsoft 365 contacts into Zendesk Sell. We recommend using Zapier to integrate Sell and Microsoft 365. To learn more about Zapier, and to find the most popular Zap templates for Zendesk Sell and Microsoft 365, see Using Zapier with Sell.
What do Zendesk Sell customers need to do?
If you have a Zendesk Sell account with any of the Microsoft 365 integrations enabled, each account user needs to reauthorize from basic authentication to modern authentication using their own Microsoft account.
If your email is still connected to Sell by Microsoft basic OAuth, you must change the model of authorization from basic OAuth to modern authentication.
Where can I find more information?

As it appears that the integration between Gsuite and Sell is handled over APIs is there such an integration in the plans for Exchange online (365)?
Speaking candidly does Sell have any plans to update the email channel integration (away from legacy protocols, and perhaps with a more limited scope)? This is debatably the most valuable component of the sell platform. For an org like mine my largest concern is scoping the email that the sell platform has access to. The nature of our business means that our sell resources may receive regulated data. understandably we cant have unrestricted access to our employee and potentially client data in a third party platform; and this is what is preventing us from fully utilizing this feature.
I reached out to our team of developers about your questions and they let me know the following: We have recently updated the way Exchange online connects from legacy authentication to Oauth authentication over IMAP. While deprecating basic auth, Microsoft has announced that it will be supporting Oauth over IMAP (article here: https://developer.microsoft.com/en-us/office/blogs/end-of-support-for-basic-authentication-access-to-exchange-online-apis-for-office-365-customers/). We do have switching to Microsoft API on our longer term roadmap, but nothing on the immediate one.
