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. This update promises to increase the support up to 1000 channels per team and 5000 members per channel, removing previous limitations.

Note to self: Merging files before CUCM upgrade

I ran into an issue when upgrading (patching) a CUCM 7.1.2 tonight, and I couldn't see any readme files on cisco.com explaining the problem. However, I came across a blog post mentioning something similar.

When you download patches from cisco.com, they might be big and split into two or more files.
One way to merge them is using the "copy /B" in a dos prompt.

Example: When you have downloaded the two files "UCSInstall_UCOS_X.X.X.XXXXX-XX.sgn.iso_part1of2" and "UCSInstall_UCOS_X.X.X.XXXXX-XX.sgn.iso_part2of2", simply merge them by typing: "Copy /B UCSInstall_UCOS_X.X.X.XXXXX-XX.sgn.iso_part1of2+UCSInstall_UCOS_X.X.X.XXXXX-XX.sgn.iso_part2of2 UCSInstall_UCOS_X.X.X.XXXXX-XX.sgn.iso

The process will take a few minutes, and should complete with "one files copied" (You need to be in the folder where these files are located).

Once this is done, you put the merged file in a folder which you can connect to from the CUCM.
(Tip: I use xlite as a ftp server for this purpose :)
