script to retrieve information via O365 with a valid cred

For most people, you will just have to install the MsOnline module

Install-Module MSOnline

If you want to use the commented out Azure stuff, you will have to install AzureAD

Install-Module -Name AzureAD

Now, with FLAGS! By default, will grab all data.

FLAGS
-U               Get Userlist
-users_detailed  Get detailed information for each user
-users_ldap      Pull down user list in ldap style format
-G               Get Group list
-M               Get Group Membership
-D               Get Domain list
-C               Get Company info

-all             Do simple enum - like enum4linux (-U -G -M -D -C). This is run if no other options are selected.
-outputfile      Output file prefix

Example Usage:

.\o365recon.ps1 -outputfile TEST_OUTPUT

No parameters are required to run. It will prompt you to log in, and then it will retrieve all information it can about that account's O365 configuration.

Retrieves:

• Company Info (address, etc)
• Domain Info (other domains)
• Full user list
• Full group list
• Group membership for every group

You'll see that the code for the Azure version is commented out, but it can be swapped in if you prefer that method.
