Speaker Attributions in Live Captions

Live captions improved accessibility of Microsoft Teams. Identifying who is speaking when there are multiple speakers in a meeting makes live captions more useful and improves comprehension.

Speaker attribution

Note: Remarks made by participants joining from a conference room device will be attributed to the room rather than to an individual in the room.

Microsoft Teams retirement of DMG on October 6th 2020 for macOS

Microsoft will be retiring distribution of the macOS MS Teams client via DMG file starting on August 7th 2020 with DMG distribution being fully retired by October 6th 2020. Instead they recommend the utilisation of Teams via the standard PKG file, which is where they will continue to invest.

Introducing the List app in Teams

The Lists app in Microsoft Teams brings lists in team SharePoint sites into the collaboration and teamwork canvas of channels and facilitates conversations around list items. With this app, end users can work on their favorite lists from within Teams.

Lists in Teams


After adding the Lists app, users can carry out all functions of Microsoft Lists (home) and SharePoint lists, including adding/editing columns, filtering, sorting, formatting, and exporting to Excel.

  • Create a new list which will reside in the team site, and pin the list to the channel tab
  • Pin any existing list they have access to the (the or a) tab
  • Start a channel conversation about a list item after clicking the list to see a full stage view.

Lists created using the Lists app and Lists created in SharePoint are identical.

Device tagging functionality in Microsoft Teams

Within the Microsoft Teams admin center, you will be able to create, assign, and delete tags to devices you have deployed. You can add one or more tags to devices, use filters to view devices that match the tag you specify, and then perform actions the devices that have that tag.

Tags will also be available as a filter option, thus allowing you to select devices associated with a particular tag.

New Riverbed CDN available in Microsoft Teams

Soon you will be able to use a new Enterprise Content Delivery Network (CDN), Riverbed, should you need a CDN for live events in Microsoft Teams.

You can select Riverbed via PowerShell, and Riverbed will be an option in the Microsoft Teams admin center.

Move files and easily keep sharing

Move and keep sharing is a new feature that allows your end users to easily re-share a file with all the direct collaborators (e.g., the users who had previously received a share for that file) should it be moved.

If an end user chooses to do so, Microsoft will provide direct collaborators with the new link or with direct permissions that match those that they had at the source location. They will also send collaborators an e-mail that notifies them that the file has been moved should the owner reshare the file location.

When your users move files across site collection boundaries, they will see this new option. It is unchecked by default.

SharePoint lists and libraries – improved image columns

List and library users will see a new column type called Image when adding new columns.

Once an Image column is added to a list or library, users can:

  • Add an image using the list or library form.
  • View, replace, or remove the image when viewing the item or file properties in the form.

When users are browsing the list on a mobile device, they will be able to upload an image from the mobile device simply by taking a photo with their camera.

New: Manage how long guests can access SharePoint Online and OneDrive files

One of the strengths of SharePoint and OneDrive is that it facilitates sharing and collaborating among peers, not only within an organisation but also with people outside the organisation (guests).

In order to better manage sharing, tenant admins will be able to create a policy to revoke guest access to SPO sites and individual OneDrives after a defined period of time. With this policy, you can limit guest user access; thus guests who are no longer active partners will not retain indefinite access to documents and files.

  • This policy is not retroactive; it does not apply to guests who already have access to sites, documents and files.
  • The policy applies to a user’s access to a given SPO site or individual OneDrive. When the access period reaches your policy threshold, such as 10 days, then the guest loses access to all content in that site. Guest access expires on a site-by-site basis, determined by when the guest was granted access to each site, whether that is an SPO site or an individual OneDrive.
  • After a guest loses access to a site, any user with the ability to share content externally can re-invite the guest to each document or item as needed.

SharePoint site administrators can extend access at any time, up to the limit of the tenant policy. For example, if the tenant policy is 10 days, and today is the 10th of the month, the SharePoint site admin could extend access for an external guest to the 20th of the month. There is no limit on the number of time a site admin can extend access.

SharePoint site administrators will receive e-mail notifications advising of upcoming guest user access expirations.
