During a recently migration project, I had an issue passed to me which required me to create a script to find all Teams channel meetings with specific users calendars. During the migration, Teams meetings were recreated to reflect the destination tenant but due to a limitation of the migration tool, this didn’t include Teams channel meetings. We then needed to find where users had channel meetings present in their calendars.

To find these meetings, I created a script which I have made available on GitHub to report on channel meetings from a users calendar. This simple script takes an array of email addresses belonging to your Teams. It then loops through events in a specific users calendar to determine which have been created by the Team, highlighting the Teams meetings in the output.

It’s not prticularly complex and does not provide a huge about of information on it’s own but built into a larger report can help identify these meetings quickly. Unfortunatly the Microsoft Graph API does not support filtering on nested values currently so the script must return all meetings for a specific user before filtering but it gets the job done!

connect-mggraph -Scopes Calendars.Read

##Variable to contain all of the team email addresses
$EmailAddresses = @(
    "serviceteam@seanmcavinue.net",
    "PlannerGroup@seanmcavinue.net"
)


##Replace userID with each user you want to check
$Events = get-mguserevent -userid db3a70f1-8e82-4a6d-a936-4695f1f7702a -All
    
    
foreach ($Event in $Events) {
    if ($EmailAddresses -contains $Event.Organizer.EmailAddress.Address) {
        $Event | fl CreatedDateTime, Subject, Organizer
    }else{
        #write-host $event.Organizer.EmailAddress.Address -ForegroundColor red
    }
}

Make sure to customize the variable and UserID in the script for your environment, then add your next steps within the IF statement to integrate this into your current reporting!.
