channel: unarchive

Namespace: microsoft.graph

Restore an archived channel. Unarchiving restores the ability for users to send messages and edit the channel. Channels are archived via the channel: archive method.

Unarchiving is an asynchronous operation; a channel is unarchived when the asynchronous unarchiving operation completes successfully, which might occur after this method responds.

Note: An archived channel that belongs to an archived team can't be unarchived. Unarchive the team before you unarchive the channel; otherwise, the request fails.
