External Sharing in SharePoint and OneDrive is changing: What You Need to Know

on
In an ongoing effort to create a more secure environment by default, Microsoft is introducing an important security update that will affect how external users access content shared through SharePoint and OneDrive. Starting July 1, 2025, any links shared with external users before your organization enabled Microsoft Entra B2B integration will no longer work. This change applies to all organizations that have already enabled or will enable SharePoint and OneDrive integration with Microsoft Entra B2B (Most organizations I have looked into so far).

Loop in Channels for Microsoft Teams

on

Loop has gradually been added to Microsoft Teams, and now the time has come for Loops in Channels

Loop components are collaborative components that allow users to crowd-source an agenda, track a group's action items, or take notes collectively. With Loop components, users can collaborate right inside a chat message or channel conversation. Everyone in the chat or channel can edit the component inline, and changes are visible instantly.

To send a Loop component in a channel, users can select "Actions and apps" in the post compose box, then select "Collaborate with Loop". They can then select the type of component they want to insert into their message, enter content into the component, and select "Send". Everyone in the channel conversation will be able to edit the content inline.

Loop components are saved automatically to the user's OneDrive, which means they can be found from Office.com in addition to Teams. Users are encouraged to give their components easy-to-remember titles to help them search for and find them quickly.
