Leavers script

Question

Hello,

I'm looking for help with a Powershell script to do the following when a user leaves the organisation:

• Convert their mailbox to a shared mailbox
• Remove any licenses assigned to their account
• Remove them from the GAL
• Where applicable delegate other users to access the shared mailbox
• add a generic out of office message
• forward emails on the shared mailbox to another user

I'm a complete noob to Powershell and find undertaking the above tedious/time consuming.

Thanks in advance.
