Exchange Online PowerShell Commands
Here is a list of Exchange Online Powershell commands that I have had to research to fix some somewhat obscure issues.
Connect to Exchange Online with MFA
Connect-ExchangeOnline -UserPrincipalName useraccount@domain.com -ShowProgress $true
Add email alias to Office365 Group
Get-UnifiedGroup #Returns the List of all groups in Office365 Set-UnifiedGroup -Identity GroupName -EmailAddresses @{Add="newalias@newdomain.com"}
