Documenting with PowerShell: Documenting mailbox sizes and settings

Kelvin Tegelaar | 29 Aug, 2021 | 1 Mins Read

At my MSP, we like being aware of obscene growth of mailboxes and weird mailbox settings so we can warn our users or help them find a better workflow, This is why we document their mailbox size, and the settings of the mailbox to our documentation system. Our account managers and vCIOs can easily log into the documentation system at a QBR and explain to our clients where they could make some improvements.

To do this, we use the Graph API reporting option. These reports are available for all exchange users and tell us exactly what the current size of the mailbox is, how many deleted items there are and how many items are in use in total.

Last week I watched Merill Fernando talk to Alex Pavlovsky and Marilee Tuscak from the Entra team about something I’d kinda put under the “needs a GSA licence” branch and i’d check it out later, turns out that like most people, I half-assed the documentation and it turns out it doesn’t. There’s two features that come with any P1 license; Compliant network check and Source IP Restoration. So BP, P1, or even frontline worker licenses already have this.

CyberDrain CTF returns! (and so do I!)

It’s been since september that I actually picked up a digital pen equivalent and wrote anything down. This was due to me being busy with life but also my side projects like CIPP. I’m trying to get back into the game of scripting and blogging about these scripts. There’s still so much to automate and so little time, right? ;)
