Add a calendar ics with Powershell

Hi MKMVMN,

you can try to download the .ics file and then add it tu multiple users with this script:

# Install the Exchange Online module if not already installed
Install-Module -Name ExchangeOnlineManagement

# Import the necessary modules
Import-Module ExchangeOnlineManagement

# connect to Exchange Online
Connect-ExchangeOnline

# Path to the .ics file
$icsFilePath = "C:\path\to\shared_calendar.ics"

# List of user email addresses
$userEmails = @(
    "email address removed for privacy reasons",
    "email address removed for privacy reasons",
    "email address removed for privacy reasons"
)

# Loop through each user and add the .ics calendar
foreach ($userEmail in $userEmails) {
    try {
        # Access the user's mailbox
        $mailbox = Get-Mailbox -Identity $userEmail

        if ($mailbox) {
            # Load the .ics file
            $icsContent = Get-Content -Path $icsFilePath -Raw

            # Add the .ics calendar to the user's mailbox
            Add-MailboxCalendarFolder -Identity $mailbox -Name "Shared Calendar" -Calendar $icsContent

            Write-Output "Successfully added calendar to $userEmail"
        } else {
            Write-Output "Mailbox not found for $userEmail"
        }
    } catch {
        Write-Output "Error adding calendar to $userEmail: $_"
    }
}

# Disconnect from Exchange Online
Disconnect-ExchangeOnline -Confirm:$false

• Ensure the path to the .ics file is correct.
• Make sure you have the necessary permissions to access and modify the users' calendars.
