PowerShell scrips for delegated access

What is the use-case behind it? Did you know that OneIM 8.2.1 supports setting SendAs permissions for Exchange on-prem mailboxes and 9.0/9.1 supports it for Exchange Online?

we are using 8.2.1.Use case is to convert user mailbox - shared mailbox for 60 days post termination and then remove all delegated permissions after 60 days and then convert back mailbox to user

Okay. Sounds like a special PowerShell script is better suited for the task. A quick google search gave me these commandlets and samples.
