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

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).

New Feature in Microsoft Teams: Forwarding Messages to and from Channels

An upcoming Microsoft Teams feature will allow users to forward posts and reply messages to and from channels, enhancing collaboration by reducing limitations on the type of content that can be forwarded. 

Change for users: Currently, users cannot forward messages to and from channels. With this new feature, users can select the three-dot More actions menu on any channel post or reply message and choose Forward. In the Forward this message dialog box, users can select any destination chat or channel, with channels now included in the people picker.

Admin Impact: This feature will be enabled by default. Admins can control message forwarding for individual teams or at the tenant level using sensitivity labels control data important to the organization. If a sensitivity label is applied, message forwarding will be disabled, blocking users from sharing content outside the channel.

The feature will according to the Roadmap ID 469508 be rolling out in January or February 2025.
