New - Identify which groups have been created by Microsoft Teams
Update to version 1-1 - 07 July, 2018 -
Updated version now identifies which Office 365 groups (Unified Groups) have been created by Microsoft Teams.

=============================================================

Part 1 - Introduction - 
Exchange and Systems Administrators need to check constantly which groups users are members of. Group membership is important for many reasons, especially so when in a Hybrid Exchange environment or you are planning on migrating to Office 365. Groups will be used for accessing resources, security, management, and distribution, as well as Office 365 licensing if you use that feature.

Administering groups in Office 365 also involves managing Office 365 Groups, also known as Unified Groups, which are created automatically by default when clients create Microsoft Teams and create plans in Microsoft Planner.

To make it easier for myself (and you), I have created the 'Group Membership Pack for Office 365, Local AD and Exchange'.

Group Membership Pack for Office 365, Local AD and Exchange
This pack of ten PowerShell scripts will generate csv reports of ALL groups and their members for -
Local AD and Exchange On-premises, including dynamic distribution groups
Azure AD, and Exchange Online, including dynamic distribution groups
Office 365 Groups (Unified Groups).
I have also included scripts to query and export all the groups a single user is a member of in -
Local AD and Azure AD.

Group and User Attributes
All my scripts export the most important attributes of both the group and the members, for example, whether the group is synced from on-premises, the email address of the group, whether the groups is public or private (for Unified Groups), etc.

Filtering the reports
Reports are useless if you don't know how to get the information you need.
If you don't really understand how to filter information in csv files in Excel, now is the time to learn.
It is strongly recommended you are comfortable on filtering columns in Excel to get the best results.
I will be providing some tips on some filters to apply to get specific results, but it really is up to you to determine how to apply filters to get the information you need.

Pre-requisites

To run these PowerShell scripts, you must first connect to either Exchange Online or Exchange On-Premises. 

Follow my tutorials and use my Office 365 PowerShell connection scripts to connect to Exchange Online. Note that the Exchange Local server needs to import the Active Directory module in PowerShell, so the machine that the scripts run on must have the AD tools installed.

Note - You must have the directory - c:\reports - created prior to running the scripts or edit the $logpath variable in the scripts that generate the group membership reports.


Connect to Exchange Online - see tutorials below
- How to configure your desktop PC for Office 365 Administration - including MFA - Link
- How to connect to Office 365 and Azure via PowerShell - Link
- How to connect to Office 365 via PowerShell with MFA - Multi-Factor Authentication - Link
- Office 365 and Azure PowerShell Connection Script (Non-MFA) - Download Link
- PowerShell Office 365 Connection Script with Modern Auth (with MFA) - Download Link

=================================================================

Editing the scripts for log path change

Note that you only need to edit the scripts if you want your reports created in a different folder from the default - c:\reports.

To edit the default report location, perform the following.

Open the script in PowerShell ISE or your favourite script editing program.

Scroll down until you find the section with the variable - $logpath = "c:\reports"

Update the path (if needed), to the path you want your reports generated.

Repeat for all scripts and save the updated scripts for future use.

Confirm that the folder(s) exist on the computer you are running the scripts on.

=================================================================

Generating and analyzing the reports

Connect to either Office 365 or Local Exchange depending on the reports you wish to run.

Office 365 - Exchange Online - (Part 1)

- Note that you only run the scripts starting with - Office 365

Exchange Local and AD Local (Part 2)

- Note that you only run the scripts starting with - Local

Select your script -

Process for running the scripts - Office 365 Scripts

Open PowerShell and connect to Office 365 (use pre-requisite tutorials at the top of this article)

Change to the directory that the scripts are located.

Type in the script name - 

Example - O365-EXO-AllExchangeDistGroupsAndRecipients-v1-x.ps1

Press enter -

The script will run and generate the csv report by default to 'c:\reports' or the folder you updated the script to.

Analyzing and filtering the reports -

Apply filters to each of the csv reports to determine the information you need.

Examples of popular filters to apply to reports will be included with each of the script details below.

Remember to clear the filter in Excel before applying a different filter again.

Multiple filters can be applied.
