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). External users trying to use old links will see an error message saying the organization has updated its guest access settings. To regain access, the content must be reshared. Highlights of how the change affects organizations who have enabled B2B: All external sharing will require guest registration. External users must be added as guests in your Microsoft Entra directory. Access will be managed through Microsoft Entra B2B Invitation Manager. T...

New Microsoft Teams Experience: Chats and Channels are being consolidated into a single app

on
Already available in targeted release, Microsoft Teams has been "streamlined" into putting chats, teams, and channels into a single app. Here’s what you need to know about the new features and how they can benefit you.

Previously, users had to navigate separate Chat and Teams views, which could be cumbersome and time-consuming. With the new update, all conversations whether they’re individual chats, group chats, or team channels are now unified in a single Chat view. This means you can easily switch between different types of conversations without losing context.


The application also has a couple of new features like: 
  • Custom Sections: Organize your projects and topics with custom sections that can include individual, group, and meeting chats, as well as channels.
  • New Filters: Focus on what’s important with filters for Unread, Chat, Channels, Meetings, and more.
  • @Mention View: Quickly access all your personal @mentions in one interactive list.
You can tailor the new chat and channels experience to suit your preferences. By default, the combined Chat view is enabled, but you can choose to keep chat, teams, and channels separate if that works better for you. Simply go to Teams Settings to make these adjustments (there are no admin controls for this). Additionally, you can turn on message previews in Settings if you prefer to see a snippet of each message in your list.

As mentioned, this is already available for users in the targeted release, but it looks like it might take some time for the feature to reach all tenants. The latest Message Center message is indicating GA in January. This is related to the following Roadmap Item.
