<# .SYNOPSIS
This script can be used by a tenant that wishes to pull resources out of another tenant.
For example contoso.com would run this script in order to pull mailboxes from fabrikam.com tenant.
This script is intended for the target tenant and would setup the following using the SubscriptionId specified or the default subscription:
1. Create a resource group or use the one specified as parameter
2. Create a key vault in the above resource group specified as a parameter
3. Setup above key vault's access policy to grant exchange access to secrets and certificates.
4. Request a self-signed certificate to be put in the key vault.
5. Retrieve the public part of certificate from key vault
6. Create an AAD application and setup its permissions for MSGraph and exchange
7. Set the secret for above application as the certificate in 4.
8. Wait for the tenant admin to consent to the application permissions
9. Once confirmed, send an email using initiation manager to the tenant admin of resource tenant.
10. Create a migration endpoint in exchange with the ApplicationId, Pointer to application secret in KeyVault and RemoteTenant
11. Create an organization relationship with resource tenant authorizing migration.
