“Bring your AI to work” is here: Microsoft edition - What Multiple Account Access to Copilot means

Multiple Account Access to Copilot On October 1. 2025 Microsoft released a blog post explaining how employees now can use Copilot from their personal 365 plans to work on organizational data. This is of course, an extension of the already existing "Multi account" feature that was released for corporate accounts a "couple of months" ago. In other words, “bring your own Copilot” is now a real thing in Word, Excel, PowerPoint, Outlook, and OneNote on desktop and mobile, with enterprise protections intact. “Bring your AI to work” is an important topic, and banning AI altogether might not be the answer. Whether sanctioned or shadow, AI has already entered everyday knowledge work. Microsoft’s new multi‑account access offers a safer path where employees can use Copilot from their personal Microsoft 365 subscriptions on work files, while the file’s access, auditing, and compliance still flow through the work identity and tenant.

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 :)
