How this will affect your organization
Connectors support in Microsoft Teams is transitioning to a new webhook URL format to enhance security. In the future, connector webhook URLs will contain the name of the tenant in them. This will help the organization filter egress traffic.

Teams desktop app for Mac: Include computer sound in a meeting
How this will affect your organization
With this update, Mac users can share audio from their speakers with other meeting participants, such as when they share a video with sound as part of a collective viewing experience.
This feature will be available to all Mac users in your tenant unless you have set the ScreenSharingMode policy to None. (opens in new tab)
This feature requires a one-time installation of an audio driver. Users will be prompted to install the audio driver when they select Include computer sound from the Share content tray in a meeting. Once installed, users can freely toggle the functionality on or off before or after they start sharing a desktop or window.
When this will happen
Begins in late January and should be complete in early February 2021.

Microsoft Teams will queue sent messages when offline
IMPACTS END USERS
How this affects your organization:
Currently, should a user attempt to send or edit Teams messages while offline, Teams labels those messages as a failure. Once the device is reconnected, Teams prompts users to retry or delete the messages.
In phase one of this update, Teams messages that are sent while a user is offline will be queued on the local device. Teams will automatically send the messages when the device resolves connectivity issues within 24 hours. However, if the message remains in an unsent state for more than 24 hours, the message will fail and Teams will prompt the user to resend or delete the message.
In phase two, Teams applies this same capability to editing messages that are in a queued state.
When this will happen
begins in late January and should be complete in early February 2021.

Microsoft Intune
Microsoft 365 apps version 16.44 and higher to install on macOS 10.14 and higher Given that Microsoft 365 has ended support for macOS 10.13.x in November 2020 (MC223176) you may not be affected; you have likely updated your OS or devices. You will not be impacted if you are currently managing macOS 10.14 or higher devices. However, if you are currently managing macOS 10.13.x devices that have Microsoft 365 apps installed, these app installations can be updated up to version 16.43 using Microsoft Auto Update. But Microsoft 365 apps are no longer supported on macOS 10.13.x and will not receive any security updates or bug fixes in the future. It is recommended that these devices are upgraded to macOS 10.14 or higher to install the latest Microsoft 365 apps. Intune moving to support Android 6.x and higher in April Given that the Office mobile apps for Android ended support for Android 5.x (Lollipop) on June 30th, 2019 (MC181101) this may not affect you; you have likely already upgraded your OS or devices. However, if you have any device that is still running Android version 5.x, or decide to enroll any device that is running Android version 5.x, please note that these devices will either need to be upgraded to Android version 6.x (Marshmallow) or greater, or they will need to be upgraded to a device that supports Android version 6.0 or greater.
Microsoft Outlook
Outlook on the web – Message reminders
IMPACTS END USERS
How this will affect your organization
After Outlook assesses that a user might have forgotten to respond to or follow up on emails, the user might start seeing these messages brought to the top of their inboxes. If applicable, a maximum of one email will be brought to the top of the user’s inbox at a time.
Users can disable this in Settings/Layout/Message reminders.
What you need to do to prepare
This feature will roll out default on. If you don’t want this feature to roll out to your users, please follow the below instructions to disable it using PowerShell:
- Parameter is set under Set-OrganizationConfig.
The MessageRemindersEnabled parameter enables or disables the message reminders feature in the organization. Valid values are:
- $true: Message reminders are enabled
