Using Flow to create Microsoft Teams online events via Microsoft Graph

I had a Flow hack a while back to have a Flow button that will instantly create an online teams meeting. Recently, I adapted it into a trigger event that turns my Outlook calendar events (where I’ve forgotten to make it a meeting) into an online meeting.

Sometimes, we create a Outlook meeting but we meant to create a @MicrosoftTeams meeting
We can use @MSPowerAutomate to patch that, via @microsoftgraph

This is #FlowNinja hack 111

The techniques needed a bit more exploration, so I did that, and recorded it as a quick 15 minute recording on my YouTube channel. Enjoy!

This is a Flow (Power Automate) that uses Microsoft Graph to create a Teams meeting event invitation. You can use this to invite people inside or outside of ...

Difference between beta, edu and v1.0 of MSGraph #microblog

I find this interesting - source: digging around MicrosoftTeams powershell and Mikael Svenson's blog post on enabling Teams programmatically. 

What's funny, because what I found strange is when Mikael says this:

The creation of the group itself happens against the /edu/groups which I’ve never seen before, but that’s not interesting.

Because that's the bit I found totally interesting.  Why does the PowerShell need the /edu/ endpoint?
Hop over to Graph Explorer we can play with this:

Comparing different endpoint: v1.0

endpoint: beta

endpoint: edu

It becomes clear why we need the /edu/ endpoint.  It has this bit of information:

"creationOptions": [
    "SkypeSpaces",
    "ExchangeProvisioningFlags:481"
],

The hint that a Team is provisioned seems to be the flag "SkypeSpaces"

Interesting.

Naturally, one would ask.  So if I want to enable Yammer, Planner or PowerBI on an existing Unified Group.  Do I POST an update to creationOptions?

Very.  Interesting.
