Microsoft is unlocking the "Full Potential" of Private Channels in Microsoft Teams: What You Need to Know

on
It has been a while since I posted something just about a Microsoft Teams update, as a lot have been Copilot in Teams to be honest. But here is a real Microsoft Teams update I think is worth knowing about, and it involves Security and Compliance as well. Microsoft is rolling out a "major" update to private channels in Teams, starting in late September 2025 and continuing through mid-December. This biggest change in this update is a shift in how private channel data is stored from individual user mailboxes to a dedicated channel mailbox. Not only will this simplifie compliance management, it will also and align private channels with shared channels, making governance and experience more consistent across Teams.

The Backup Skype for Business script is now live

on
As promised in today's session, here is the announcement of the general availability of the backup script for Skype for Business on premise.

It is continuation of the backup-lync2013 script, with a few minor tweaks to make it work with SfB.
But as I was going through the script to make it compatible, I also added a couple of other tweaks.

Here are the highlight of this version (called v 4.00)

  • Change: Script renamed to Backup-SfB.ps1
  • Change: Script edited to work with Skype For Bisiness server deployment (TAP Bits)
  • Change: Shortened filepath by using hostnames, not fqdn for naming
  • Change: New destination = c:\ucbackup
  • New feature: Added a switch to set a password for certificate $CertPass
  • New feature: Certificate export will now add "usages" for the exported certificates
  • New feature: A warning is displayed if a cert is not exportable
  • FEATURE REQUEST: Send an email notification on completion
  • Bugfix: If the same certificate is used for multiple usages, the next export (with an existing thumbprint) is skipped, only the first usage is displayed

I hope you find this useful, and I do appreciate feedback so I can make it even better in an upcoming event.

The script can be downloaded from the Technet Gallery
