Hi @Stephen
Teams can't merge multiple teams into one, but you can create a shared channel for your team. You can invite members of other teams to a shared channel, and you can share files with other users in a shared channel.
Shared channels in Microsoft Teams create collaboration spaces where you can invite people who aren't in the team. Only the users who are owners or members of the shared channel can access the channel. While guests (people with Microsoft Entra guest accounts in your organization) can't be added to a shared channel, you can invite people outside your organization to participate in a shared channel by using Microsoft Entra B2B direct connect.
You might want to use a shared channel if you want to collaborate with a group of people who are all members of different teams. For example, people from engineering, sales, and support who all work on different aspects of the same project or product could use a shared channel to collaborate.
