May 17, 2019 PowerShell, Windows

In a previous post I installed PowerShell on my Arch Linux based system. Here I use it to check and amend Office 365 mailbox permissions.

If you needed to give everyone Reviewer access, you would issue something like the below:

1
PS /home/andy> Get-MailboxFolderPermission -Identity andy.pike@pikedom.com:\Calendar -User everyone -AccessRights Reviewer

To disconnect, issue:

1
PS /home/andy> Get-PSSession | Remove-PSSession
