Description

As per my comment on #909 Teams is now spitting out a new Channel ID format (ending in @thread.tacv2) which is breaking the validation in isValidTeamsChannelId.

Steps to reproduce

• Create a new Team
• Call o365 teams message list against the General channel

Expected result

Get the messages from the channel

Actual result

Something like '19:[email protected] is not a valid Teams ChannelId'

Environment

Win10 Enterprise, PowerShell
