powershell - Exchange online can I get a list of all mailboxes

Question

I need to get a list of all mailboxes.

Can I get this list with EWS and PowerShell?

Exchange online shell will not be installed on the server where I run the script.

Thanks for your support

Answer 1

With PowerShell you can just simple call the Get-MailBox powershell command.

This is working for on-premise and O365 mailboxes as well. For O365 environment sooner or later you will need to transfer to modern authentication, but basic authentication will still work for a while. This is the easier way of I can think of.

Based on my knowledge it's not possible to list all mailboxes using entirely with EWS.
