Key points:

• Microsoft 365 Roadmap ID 82731.
• Timing:
  • Targeted release (entire org and specific users): will begin rolling out in early September and expect to complete rollout late October.
  • Standard release: will begin rolling out in late October and expect to complete rollout late January.
• Roll-out: entire org and user level
• Control type: admin control
• Action: read over the tenant admin and end user-facing documentation to understand all expected changes.

How this will affect your organization:

The new modern comments experience will affect files where the first comment was added after your organization has the tenant admin setting enabled. Existing files with comments will not be affected

Modern comments can’t be read by PowerPoint 2019 or older, including subscription and perpetual versions. End users will be notified about unsupported comments in their presentations, with a prompt to open the file in PowerPoint for the web to review the modern comments. A full breakdown of experience by PowerPoint version is available in the tenant admin documentation.

The new commenting experience answers several popular feature requests and significantly improves collaboration.

• A comment will now anchor to objects. If users move the object, the comment moves with it.
• Comments can now be anchored to text. This feature will be rolling out to Production Windows and Mac builds between June and August of 2021. Users on web and Insiders builds may have this feature earlier.
• Comments in the margins on web. Comments will appear to the right of user’s slides by default on web, keeping their comments closer to their content.
• Users can now mark threads of comments as resolved. Resolved comments won’t appear in the margin but can still be seen in the Comments Pane.
• Modern comments can only be edited by the person who created them.
• Improved notification emails let recipients see the context of the comment and reply directly from the email.

PowerPoint modern comments are available today behind a tenant admin setting which is off by default.

• This update will change the default setting from off to on.

What you need to do to prepare:

The following steps are recommended to prepare for this change:

• Understand the experience on different versions of PowerPoint via the table provided in the tenant admin documentation. Determine if this experience is suitable for the needs of your organization.
• This update will roll out to end users according to their channel. This means different users in your organization may be on different comment experiences until rollout is complete across all channels. If you’d like your tenant to turn on modern comments all at once, please enable the feature via OCPS or group policy.
• If you’ve already explicitly set the PowerPoint modern comments tenant admin setting, that state will be respected. If you do not wish to receive this update, please make sure this feature is set to off in your tenant admin settings.
  • If you decide to disable the feature, we’d love to understand more about why. You can send us feedback at [email protected].

Microsoft 365 applications and services

• Timing: Microsoft 365 apps and services no longer support IE11 as of today, August 17, 2021.
• Action: To access Microsoft 365 apps and services using a supported platform, open with Microsoft Edge, another supported browser, or use an applicable Win-32 app (if available).

For a full list of Microsoft apps and services that have ended (or will end) support for IE11, please review Microsoft apps and services to end support for Internet Explorer 11.Note: While Microsoft 365 apps and services no longer support IE11, the IE11 desktop application remains a supported browser by Microsoft until June 15, 2022. On June 15, 2022, the IE11 desktop application will be retired and go out of support on certain versions of Windows 10.

Please see our retirement announcement and FAQ page for more details.

How this will affect your organization:

Important: Support is now unavailable for Microsoft 365 apps and services on IE11. Additionally, you should expect no new features and that the daily usage experience for users could get progressively worse over time until the apps and services are disconnected. Banners will be used to communicate and to alert users to upcoming changes in experiences, such as app or service disconnection and/or redirection.

Initial degraded experiences beginning today, August 17, 2021, include:

• Outlook Web App: Users logging in with AAD accounts will have the full experience but will not receive new features moving forward. Users logging in with Microsoft Accounts (MSA) will be redirected to the Outlook Web App Light experience.

SharePoint’s Open with Explorer and View in File Explorer in IE11 features:

• These features only exist in IE11 and while some customers may continue to use them, they will remain in maintenance mode and will not receive further development. We recommend transitioning to Microsoft Edge and OneDrive Sync for a better user experience and will soon bring the View in File Explorer feature in the Modern SPO Document Library to Microsoft Edge as well (more details to come). Please read this article for more information.

What you need to do to prepare:

To avoid an unsupported and degraded experience, or one where you are unable to connect to Microsoft 365 apps and services, upgrade to Microsoft Edge as soon as possible. Microsoft 365 apps and services will continue to support Microsoft Edge.

Additional Information:

• If you’d like help upgrading your organization’s devices to Microsoft Edge, FastTrack can help.
  • Self-service automated tools are also available through the Microsoft 365 Admin Center.
• For help with web app and site compatibility, learn more about the App Assure program.
• Read more about these changes in the Lifecycle announcement.
  • Our blog also provides more information about these announcements.
• To learn about the IE11 desktop application retirement on June 15, 2022, please read this retirement announcement blog.

As best practice PST files should not be uploaded on OneDrive for Business and SharePoint Online team site document libraries due to the impact on storage and network bandwidth. When PST files are uploaded on OneDrive for Business and SharePoint Online team site document libraries, Outlook updates PST files generating multiple versions which leads to storage being quickly consumed by the multiple versions of the PST file.

The SharePoint Online Management Shell cmdlet Set-SPOTenant – DisableOutlookPSTVersionTrimming $true can be used to opt out until August 13th 2021. This will have no effect after the deadline. Opt out only applies to existing document libraries and does not apply to new doclib created after August 13th 2021. New behavior will be automatically enabled if you don’t opt out by deadline.

• Command: Get-SPOTenant/Set-SPOTenant
• Parameter: DisableOutlookPSTVersionTrimming
• Value: True – Opt-out to the versioning change
• False – default value

This feature is associated with Microsoft 365 Feature ID: 72237

How this will affect your organization:

As part of the change, version history for PST files will be retained for up to 30 days. Document libraries will be updated with new PST version retention limits. Once this change is rolled out to your tenant, versions of PST files stored on in your document library that are older than 30 days will be permanently deleted. With these changes the service will always retain a minimum of 30 day worth of PST versions that can be restored from.

What you need to do to prepare:

No action required – Document libraries will be updated with new PST version retention limits. If you wish to opt out of the PST version retention update, you will need to execute the SharePoint Online Management Shell cmdlet provided in this post by August 13th 2021.

To prevent uploading .PST files from the OneDrive sync app, read Block syncing of specific file types and To move .PST files out of OneDrive, read How to remove an Outlook .pst data file from OneDrive.

Users accessing the security solutions in the Office 365 Security and Compliance center (protection.office.com) will be automatically redirected to the appropriate solutions in the Microsoft 365 Defender (security.microsoft.com). This change enables users to view and manage additional Microsoft 365 Defender security solutions in one portal.

• This change impacts all customers who use the Office 365 Security and Compliance center (protection.office.com). For the full list of impacted licenses, see Security & Compliance Center – Service Descriptions | Microsoft Docs.
• This change impacts all users who log into the Office 365 Security and Compliance portal (protection.office.com), including security teams and end-users (who access the Email Quarantine experience).

What you need to do to prepare:

Redirection is enabled by default, and impacts all users of the tenant.

Global Administrators and Security Administrators can turn off redirection in the Microsoft 365 Defender portal by navigating to Settings > Email & collaboration > Portal redirection and switch the redirection toggle.

The OneDrive team is committed to bringing you the best, most secure experience possible across your devices. As such, we are ending support for the OneDrive Desktop application (sync client) on macOS Sierra 10.12 and macOS High Sierra 10.13 and focusing our resources on new technologies and supported operating systems. Going forward, only the three most recent versions of macOS will be supported. When a new major version of macOS is released, we will support the new version and the previous two versions.

Note: Both macOS Sierra 10.12 and macOS High Sierra 10.13 have been out of Apple’s mainline support since September 2019 and November 2020, respectively.

Key points:

• Timing: September 10th, 2021
• Action: review and update impacted machines as appropriate.

How this affects your organization:

How users will be impacted after this change has rolled out:

• Existing OneDrive sync client installations on unsupported operating systems will stop updating. These clients will continue to run, but their functionality will no longer be tested. It is not advised to continue to run on these unsupported operating systems.
• New installations on unsupported operating systems will be blocked.
• Bugs and issues found on or specific to unsupported operating systems will no longer be investigated or fixed.

What you need to do to prepare:

To ensure a smooth transition we recommend that you upgrade machines accordingly. We recommend you upgrade to macOS Mojave 10.14 or above. For the best user experience and longest support lifecycle, we recommend upgrading to macOS Big Sur 11.0 or above.
