Teams updates to watch: malicious link warnings, blocked risky files, and a new private backroom chat

on
Microsoft has announced three Teams updates the past months. Two that strengthen security and one that will improve how organizers coordinate events: Malicious URL Protection, Weaponizable file type protection and Private chat for organizers, co‑organizers, and presenters. Please note that timelines can shift, so treat the dates as guidance rather than guarantees. Malicious URL Protection (Roadmap ID 499893 ) Microsoft has announced link‑scanning in Teams chats and channels that warns senders and recipients about unsafe URLs.

New and improved (?) backup script for Lync 2013

on
Based on a couple of feedback's and my own experience with these backup scripts, I think it is about time to release the new and improved version.

Highlights include:

  • Bugfix to catch installations where you do not use a named SQL instance
  • Should be able to create backups from several pools when running the backup (not all services, but most important)
  • The same script will now run on both Standard and Enterprise edition.
I have not tested the script in too many multi-pool installations, and really appreciate feedback on the matter. I have tested it on both standard and enterprise version.

The script is signed, and should run on any server, unmodified.

Instead of sharing the script through Drop-box, I have posted it in the Technet Gallery, right here: Backupscript-Lync_2013_v3.ps1. It will give you an option to rate the script, or even discuss it.
