{
<#
.SYNOPSIS
Checks whether the given user exists in Azure AD or not. Returns $True or $False or empty.
.DESCRIPTION
Checks whether the given user exists in Azure AD or not. Works also with external users! Supports two enumeration methods: Normal, Login, and Autologon.
The Normal method seems currently work with all tenants. Previously it required Desktop SSO (aka Seamless SSO) to be enabled for at least one domain.
The Login method works with any tenant, but enumeration queries will be logged to Azure AD sign-in log as failed login events!
The Autologon method works with any tenant and enumeration queries are not logged!
Returns $True or $False if existence can be verified and empty if not.
.Parameter UserName
List of User names or email addresses of the users.
.Parameter External
Whether the given user name is for external user. Requires also -Domain parater!
.Parameter Domain
The initial domain of the given tenant.
.Parameter Method
The used enumeration method. One of "Normal","Login","Autologon"

.SYNOPSIS
Crawls the target organisation for user names and groups.
.DESCRIPTION
Crawls the target organisation for user names, groups, and roles. The starting point is the signed-in user, a given username, or a group id.
The crawl can be controlled with switches. Group members are limited to 1000 entries per group.
Groups: Include user's groups
GroupMembers: Include members of user's groups
Roles: Include roles of user and group members. Can be very time consuming!
Manager: Include user's manager
Subordinates: Include user's subordinates (direct reports)
UserName: User principal name (UPN) of the user to search.
GroupId: Id of the group. If this is given, only the members of the group are included.
