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.

1000 channels in Teams, sending an invite to channel meeting participants and Automatic transcription of videos

on

If you have a meeting recording but forgot to add transcriptions, it might be good to know automatic transcription will be added to files uploaded to SharePoint, Yammer or office.com. This feature is currently rolling out and should be generally available by late August. The feature is ON by default, but can be controlled by the set-SPOTenant command. If you are not familiar with how transcriptions work, here is a blogpost to get you up to speed.

Not the most technical update, but still an update that will be appreciated. According to roadmap item 127496, the number of channels per team will increase from 200 standard and 200 shared channels to 1000 channels combined + 30 private channels.  This should give organizations great flexibility within their teams. The feature is currently rolling out in preview, and should be generally available by the end of September.

Organizers of channel meetings should soon be able to also send invites directly to participants of the channel by a turn of a toggle in the invite. This will send invites directly to members' mailboxes, and the chances of missing a scheduled channel meeting should be something in the past. Roadmap item 142405 should be rolling out some time during August.
