Basic Authentication and Exchange Online – April 2020 Update

Major update: Announcement started
Applied To: All
In response to the unprecedented situation we are in and knowing that priorities have changed for many of our customers we have decided to postpone retiring Basic Authentication in Exchange Online (MC204828) for those tenants still actively using it until the second half of 2021. We will provide a more precise date when we have a better understanding of the impact of the situation.

[How does this affect me?]

We will continue to disable Basic Authentication for newly created tenants by default and begin to disable Basic Authentication in tenants that have no recorded usage starting October 2020. And of course you can start blocking legacy authentication today, you don’t need us to do anything if you want to get started (and you should).

We will also continue to complete the roll-out of OAuth support for POP, IMAP, SMTP AUTH and Remote PowerShell and continue to improve our reporting capabilities. We will publish more details on these as we make progress.

[What do I need to do to prepare?]

This change allows you more time to update clients, applications and services that are using Basic Authentication to use Modern Authentication.

Basic Authentication Retirement for legacy protocols in Exchange Online

Hauptupdate: Ankündigung

Gilt für: All customers

Updated February 7, 2020: Changed the Action by Date to accurately reflect October 13, 2020. Beginning October 13, 2020, we will retire Basic Authentication for EWS, EAS, IMAP, POP and RPS to access Exchange Online. Note: this change does not impact SMTP AUTH. There are several actions that you and/or your users can take to avoid service disruptions on client applications, and we describe them below. If no action is taken, client applications using Basic Authentication for EWS will be retired on October 13, 2020. Any application using OAuth 2.0 to connect to these protocols, will continue to work without change or interruption.

What do I need to do to prepare for this change?You have several options on how to prepare for the retirement of Basic Authentication.

  • You can start updating the client applications your users are using to versions that support OAuth 2.0 today. For mobile device access, there are several email apps available that support Modern Authentication, but we recommend switching to the Outlook app for iOS and Android as we believe it provides the best overall experience for your M365 connected users. For desktop/laptop access, we encourage the use of the latest versions of Outlook for Windows and Outlook for Mac. All Outlook versions including, or newer than, Outlook 2013 fully support OAuth 2.0.
  • If you have written your own code using these protocols, you will need to update your code to use OAuth 2.0 instead of Basic Authentication, you can reach out to us on stack overflow with the tag exchange-basicauth if you need some help.
  • If you or your users are using a 3rd party application, which uses these protocols, you will either need to
    • reach out to the 3rd party app developer who supplied this application to update it to support OAuth 2.0 authentication
    • assist your users to switch to an application that’s built using OAuth 2.0.

We are in the process of building reports that will help you identify any impacted users and client applications in your organization. We will make these reports available to you in the next few months and communicate their availability via a follow-up Message center post.

Exchange and SameSite Updates

The Stable release of the Google Chrome web browser (build 80, scheduled for release on February 4, 2020) features a change in how cookies are handled. Although the change is intended to discourage malicious cookie tracking, it’s also expected to severely affect many applications and services that are based on open standards.

For more information, see SameSite Updates on the Chromium Projects website.

Microsoft is committed to addressing this change in behavior in its products and services before the February 4, 2020 rollout date to ensure our customers are minimally impacted.

Exchange Online has already rolled out changes necessary to support this change and we do not anticipate any issues.

Exchange Server’s March Cumulative Updates will contain changes necessary to support this change. We will issue CU’s for Exchange Server 2016 and 2019 and we recommend upgrading to these versions to ensure compatibility. We’re investigating solutions for earlier versions of Exchange Server.

Given the date of our scheduled CU’s comes after Google Chrome’s release date of February 4th there might be some issues experienced by users.

To avoid issues, we recommend users switch to an alternate browser, or configure the site/URL used by OWA users to be excluded from the SameSite enforcement behavior in Chrome by using the LegacySameSiteCookieBehaviorEnabledForDomainList setting.

Additional information can be found on this page.

Windows Server 2008/R2 and Windows Server 2012/R2 end of Support and Office 365 ProPlus

MC196755
Plan For Change
Veröffentlicht am : 27. November 2019
Office 365 ProPlus delivers cloud-connected and always up-to-date versions of the Office desktop apps. To ensure that customers get the best value and experience from Office 365 ProPlus, we are sending this reminder as to the impact of upcoming changes to Windows support on Office 365 ProPlus.

How does this affect me?
As communicated in MC192504 (October 2019), we noted Windows 7 will go out of support after January 14, 2020. At this time, Windows Server 2008 will also go out of support. We understand Office 365 ProPlus customers may need more time in their migration to a supported operating system. Through January 2023, Microsoft will provide security updates for Office 365 ProPlus on Windows 7 and Windows Server 2008. But, during that time, as long as customers are still running one of these unsupported operating systems, Office 365 ProPlus won’t receive any new feature updates.

For Windows Server 2012/R2, we previously announced and stated in a support article, that Office 365 ProPlus will no longer be supported on Windows Server 2012 and 2012 R2. While Microsoft will not take any measures to block users with this configuration from connecting to Office 365 services, Office 365 ProPlus on Windows Server 2012/R2 will not be a supported configuration. While Microsoft does not anticipate any change to Office 365 ProPlus compatibility with Windows Server 2012/R2, customers may experience changes to performance or reliability issues. Microsoft Support will continue to accept calls from customers, however we may not be able to resolve issues that arise if those issues are determined to be unique to this configuration.

What do I need to do to prepare for this change?
For customers on Windows 7, we recommend that organizations migrate to Windows 10 or a supported operating system before the end of support date on January 14, 2020 in order to continue receiving new feature updates to Office 365 ProPlus. For more information, please refer to this article.

For customers on Windows Server 2008/R2 and Windows Server 2012/R2, we recommend migrating your applications to Azure. For those customers who need to stay on-premises, we recommend moving to Windows Server 2019.

Office 2013 Client Connectivity to Office 365 Services

Office 2013 Client Connectivity to Office 365 Services
Major update: Announcement started
Applied To: All customers
As previously announced via blog and MC175274 (March, 2019), Office 2013 clients’ connections to commercial Office 365 services will not be supported after October 13, 2020. After this date, ongoing investments in the Office 365 cloud services – including Exchange Online, SharePoint Online, and OneDrive for Business – will proceed based on post-Office 2013 requirements. We recommend that organizations with Office 2013 clients consider migrating to Office 365 ProPlus.

Support for Office 2016 and Office 2019 connections to Office 365 cloud services will continue until October 2023. Up to date information on current system requirements can be found under on the Office system requirements page, with related timelines available in the Office system requirements matrix.

[How does this affect me?]

Microsoft will not take any active measures to block older Office clients, such as Office 2013 and Office 2010, from connecting to Office 365 services. However, legacy clients attempting to connect to a modern, always up- to- date cloud service may experience performance and reliability issues. Customers will face an increased security risk, and may find themselves out of compliance depending on specific regional or industry requirements. Microsoft Help may not be able to resolve issues that arise due to unsupported service connections.

[What do I need to do to prepare for this change?]

In order for you to better understand whether and how your organization is affected by this change, and where you need to migrate users, there are two System Center Configuration Manager dashboards (updated as part of version 1902) that can help:

– the SCCM Product Lifecycle dashboard allows you to see which versions of Office are running on your desktops, to determine which will need updated Office apps to help ensure a seamless connection to Office 365 services
– the Office 365 ProPlus Upgrade Readiness report on the Office 365 client management dashboard helps to identify desktops in your organization that are ready to upgrade to Office 365 ProPlus with high confidence.

Use these dashboards to identify users on Office 2010 and Office 2013 clients, deploy Office365 ProPlus or a supported version of Office perpetual to those desktops, and ensure that they will have supported access to Office 365 services after October 13, 2020.
