Yes, any Copilot chat can create calendar events, not only the one inside Outlook, because the feature is tied to your profile rather than the window you are in. At the time of writing it reliably creates only one event at a time, so ask for several events separately.

Can Copilot make a priority list from my Emails and Teams messages?
Yes. With Work IQ, one prompt reaches Outlook and Teams together, so Copilot can build a single priority list from both. Commitments made only in a Teams message still surface as open items, so anything you agreed to in a chat will come back to find you.
Can Copilot summarise a Teams channel?
Yes, but not from inside the channel. There is no Copilot panel within a team or channel, but the main Copilot chat can reach your channels, so ask it there to look at a specific channel. This uses your work data, so it needs Work IQ and the full Microsoft 365 Copilot licence.
Can Copilot transcribe a recording?
No. Turning an existing video or audio file into text is a separate capability that some tools have, but Copilot does not. For Teams meetings, transcription has to be switched on at the time of the meeting. For an existing recording, use a dedicated transcription tool instead.
