“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.

When installing a database on a Standard Edition 2013 server, remember to specify the RTC instance, and save yourself some troubleshooting :).

This command worked like a charm:

Install-CsDatabase -CentralManagementDatabase -SqlServerFqdn myserver.domain.com -SqlInstanceName rtc
