How to allow guests to access company resources (Teams/SP/Shared Mailbox)

[thecomputerguy]

Client is outsourcing work for employees who are out sick.

The request is to allow guest users to be able to access specific teams, and a specific shared mailbox.

Internet/ChatGPT says to add the user as a guest through Users > Guest Users

Then create a group and add the guest user to the group. Then assign that group access to the team / shared mailbox. Is it a M365 group? Security group??

I used my own gmail as a test guest user. Created a testguestuser@contoso.com group. I then added my guest account to the group but I see no where in Teams Admin center, or Exchange admin center to assign this group as a member of the Team and/or shared mailbox.

This seems like such a complicated ask. Would a better way be to assign them some license like basic and give them a company account?

I'm an idiot ... My brain went sideways... obviously I can create a guest user and assign that guest to a team or a channel ... I just wasn't thinking.

What about giving a guest access to a mailbox or a shared mailbox? I'm not even sure how to do that.

Ok research says no on the shared mailbox ... turns out the client was explaining incorrectly.

The guest user is actually an onsite temp. I told them to stop allowing temps to use employee devices and now were just going refurbish a laptop and set it up as a temp only device.

So convuluted!
