PowerShell: Configuring Settings on Multiple Exchange Mailbox Databases

One of the strengths of using PowerShell for Exchange Server administration is the ability to perform changes to multiple objects simultaneously. In this article I will demonstrate an example of this by showing you how to update a setting on multiple Exchange Server mailbox databases at once.

In this example the public folder database associated with the mailbox databases needs to be configured. There is already one mailbox database with the correct public folder setting and we want to apply the same setting to all of the other mailbox databases on the server.

Doing this manually, one at a time would be tedious.  But thanks to the Exchange Management Shell we can do it very quickly.

First, read the desired public folder setting from the first mailbox database into a variable.

Now we can inspect the variable to see the result of that first step.

Next, we apply that public folder setting to all of the mailbox databases on the server with this single command line.

Now we can confirm that the change has occurred.

As you can see the Exchange Management Shell lets us make bulk changes with ease.
