I saw this tip on The Lazy Admin submitted by reader Andy Grogan. He wrote a script which will backup certain mailboxes based on OU. The article, script and the command syntax can be found here on TLA.
The Lazy Admin website is a great source for scripts and tips to help you out. Now that Rodney is working for Microsoft Canada, I’m sure we’ll see even more great tips and information.
I’m subscribed, and I would suggest you should be too.
