Export lists to CSV in Microsoft Lists

Export to CSV is an additional export option now available for Microsoft Lists. Lists has always had, and maintained, integration with Excel – to either bring table data in, or to export to analyze your list data back in Excel. The limiting factor was the different experience for Mac – which, for some time, was not an option.

For Windows you can export to Excel or CSV, for Macs, you can only export to CSV.

Note: The export to CSV is currently only supported inside Lists; the team is aware of this design issue and working on it.

Updated sharing experience for Microsoft Lists

Users can now share entire lists using sharing links with more granular control options, leveraging the same sharing capabilities you might be familiar with when sharing files and folders, which brings to Lists the ability to share with everyone, only certain people, view/edit and the ability to set sharing expiration.

Note: The same admin controls that manage sharing for files and folders will also apply to lists and list items.

Presenter mode empowers presenters to customize how their video feed and content appear to the audience with powerful professional layouts. The first layout, Standout, is now available to show the speaker’s video feed as a silhouette in front of shared content. That way, you can easily direct your audiences’ attention through hand gestures and facial cues, without making the viewer choose between the speaker and the content.

If you go over that limit, your meeting seamlessly scales to accommodate up to 10,000 people in a view-only experience. During this time of increased remote work, you can take advantage of view-only broadcasts for up to 20,000 attendees through the end of this year.

With the ability to see up to 49 participants in a single screen, you can enhance your virtual meeting experience where participants feel closer together even when you are apart.

Updated settings for attendees video

There are three new ways that you can now manage your attendees’ camera:

  1. Meeting attendees are able to turn their camera on or off to share video by default. You can also configure to have all attendees’ camera disabled by setting Enable camera for attendees to Off from the Meeting Options web page before the meeting.
  2. Once this new setting is turned Off, you can also reverse this setting during the meeting to allow all attendees to turn their camera on.
  3. Finally, you can also enable or disable the camera for individual attendees

Note: that these settings do not automatically turn on attendees’ camera or affect presenters and meeting organizers. This feature aims to focus on attendees to prevent disruptions during a meeting and help create a safe meeting environment.

AI-based noise suppression for Mac users

AI-based noise suppression is being expanded for Mac users. Real-time AI noise suppression feature automatically removes unwelcome background noise during your meetings. Your audio feed is analyzed to filter out the noise and retain only the speech signal. You can also control how much noise suppression you want, including a high setting to suppress more background noise. This feature is now available for all Mac users except devices with M1 ARM processor.

Expiring access for external users

To protect shared files, administrators can set a mandatory expiration period to ensure access doesn’t last forever and help avoid leaking organization data by accident. This policy can be enabled in the SharePoint admin center (both modern and classic) and applies to both OneDrive and SharePoint. Once the policy is implemented, external users will automatically lose access to content on the site-by-site level (or OneDrive-by-OneDrive level).

Note: SharePoint site administrators and OneDrive owners will have the authority to extend or remove access for the selected users.

Exclude specific files from sync on macOS

Microsoft have enabled functionality in OneDrive for macOS that allows IT admins to prevent the OneDrive sync app from uploading certain files to OneDrive or SharePoint. IT admins who are managing macOS devices in their organizations can enable this setting using the prescribed plist file entry to prevent users from uploading specific file types such as .exe or .mp3 when they sync their OneDrive files.

When this setting is enabled, the sync app doesn’t upload new files that match the specified keywords, and the files remain in the local OneDrive folder. In Finder, the files will appear with an “Excluded from sync” icon in the Status column, and users will see a notification in the OneDrive activity center explaining why the files aren’t syncing.

Alternate keys let a user specify additional columns that can also be used to retrieve records. This is useful if you need to look up records based on something other than a string (for example an Order ID number, or a Case ID). Alternate keys also enforce record uniqueness on the column(s) that are part of the key.
