Office 365 Scripts

Let's get into our favorite Office 365 Powershell scripts.

I am going to refer to our good friends at Microsoft here as they have the best gallery of O365 Powershell scripts for admins and engineers alike.

https://gallery.technet.microsoft.com/office365 (I have this bookmarked).

NB: If you do download any of these, I do recommend you test them in a test environment first and not the production environment (just best practice caution).

Also if you do benefit from any script below, please make sure you give back to the Microsoft community by giving the script a rating. Thank you for all those who contribute powershell scripts to the MS community. Many of these scripts are written by well known Microsoft MVP's. How many do you recognize?

1: Office 365 reporting tool

3: Get-DistributionGroupMembers.ps1

Much like its counterpart for Exchange 2010 this script will export to CSV all the Distribution Groups and its distribution group members. This can be handy when there are nested distribution groups and you want to run a report of Distribution groups that may be accessible externally (from the internet).

5: O365 Mail Traffic Statistics by User

This script retrieves the inbound and outbound mail traffic statistics by recipient for all available dates. It can be exported to a CSV file.

Handy when troubleshooting mailbox flow issues and possible Inbox rule interference.

Output example:

Date	Recipient	Inbound	Outbound	InboundSize	OutboundSize
03/02/2014	admin@cogmotive.com	1	0	9308	0
04/02/2014	admin@cogmotive.com	5	2	69939	19861
04/02/2014	brian@cogmotive.com	0	1	0	5897

7: Bulk Add SMTP addresses to O365 mailboxes.

Not a usual request, however it has come up before to add additional SMTP addresses to entire firms mailboxes, or a new domain. Always a handy script to have up your sleeve.
