SCENARIO
When executing SharePoint Online scripts you need to be connected to your “admin” site or the script will just fail if you’re not.
PROBLEM
When writing a script you can’t assume that you’re already connected to your SPO tenant and unlike the “msolservice” connect call you need to specify your “admin” URL which can be quite long. But sometimes you’re already connected in the Powershell session.
SOLUTION
Writing this little thing in the start of your script will check if you’re connected to the admin site and if not will call the connect-sposervice command with the URL already set.
# First we reset the sitecheck to avoid having an old result
$sitecheck=""
# This is the address of your SPO admin site
$adminurl = "https://[your tenant name]-admin.sharepoint.com"
# Now we try to get the SPOSITE info for the admin site
Try { $sitecheck = get-sposite $adminurl }
# If we get this server exception for any reason, the service isn't available and we need to take action, in this case
# write it to the console and then connect to the SPO service.
Catch [Microsoft.SharePoint.Client.ServerException]
{
Write-Host -foreground Yellow "You are not connected!"
connect-sposervice $adminurl
