Adding Multiple Email ID to O365 Groups

[siva1985]

I am trying to add multiple email id to O365 groups . Currently i am allowed to add one by one email ids. is there way to add multiple email id in one go or upload csv etc. adding one by one is too much time consuming.

You can have few hundred addresses assigned to a group, best you should use PowerShell though. Here's an example:

Import-CSV blabla.csv | % { Set-UnifiedGroup GroupName -EmailAddresses @{add=$_.address} }

where the CSV file contains a field called "address". Since the example adds aliases one by one, you should just do few at a time, or rework it to add them all at once (make sure to preserve existing aliases though).
