As you can see from the screen capture above I have added a guest user to my plan – the LU icon –
– which also happens to be me – so not a great example of collaboration – but you get the idea. We don’t yet have the ability directly in Planner to add a guest (coming soon) – but we can assign guests to tasks for guests who are already in the tenant, having been added through Teams for example (ignore the ‘2’ – I forgot to capture a screenshot when I first added me as a guest):
The important thing to remember here is that we are not federating a login with Google – and it actually creates an account in your Office 365 tenant which needs its own password – not your Google (or whatever) password – and please don’t re-use you Google password – very bad practice. The person you invite will see an e-mail (in this case in Gmail) – first verifying the e-mail address, and once you do, then you will receive an invite to Teams (in this case):
Then your guest has access to Teams and can start collaborating:
Once your guest has access they will appear to be used elsewhere – such as assigning to tasks in Planner:
One thing that may catch your guest out is the log-in Url they need to use – and for Planner just going to
will NOT work as that Url does not know which tenant you are attempting to log in to – and only accepts “work or school accounts”.
The log-in Url needs to identify the tenant – so the full Url would look something like this:
