🔓 Set up for shared mailboxes in Outlook Exchange Server

Background

There’s no built-in REST API for getting shared mailbox permissions on on-prem Exchange Servers. That means it’s not possible to find out which users have access to which shared mailboxes automatically. To solve this, we created a PowerShell script that connects to your on-prem Exchange Server and pulls the mapping between shared mailboxes and users with access. This makes it possible to bring this data into amberSearch so users can also search through shared mailboxes. You can find the script here:

https://github.com/ambersearch/Tools/tree/main/Office365/Exchange-Server

Requirements

- You should have administrator access to your on-premise Exchange Server

- The script needs to be run directly on the Exchange Server

- Exchange Management Shell must be run as administrator (not PowerShell).

Output

The PowerShell script generates a .csv file containing all shared mailbox permissions. Please send this file to the amberSearch team to enable shared mailbox search functionality in your amberSearch instance.
