PowerShell Add to Global Admin

Today I was working on adding all the new admin accounts we made for a client to the Global Admin Role for Microsoft 365 as part of the onboarding process.  Prior I had added the accounts in the local AD accounts using PowerShell and set them to sync with AD Connect.  We have a lot of admin accounts we are making and adding them one-by-one via GUI was not something I wanted to do anymore. 

#I opened up PowerShell ISE on my local computer 

#Connected to MS 365 for this client using a Global Admin account 

Connect-AzureAD 

#There are 2 variabled I needed for this command.  The first is the ObjectID of the Global Admin group 

Get-AzureADDirectoryRole | Where DisplayName -like "GL*" |  Select DisplayName, ObjectID 

#copy out the Object ID 

#The second is the ID of the user accounts you want.  I used this command to narrow it down to just the names I was looking for 

Get-AzureADUser | Where DisplayName -like "Admin*" | FT DisplayName, objectID 

#the ObjectID for the user is the RefObjectID in the below commands 

#The ObjectID of the role is the first ID. The second is the user ID.
