Azure AD business-to-business guest user accounts are a terrific way to securely grant access to apps and services for external users and partner organizations. In this article, a script is introduced that can be used to automate the guest user invitation process, integrating it more seamlessly with any custom applications.
When contacts are added to an organizations Global Address List (GAL), they do not always populate in the users personal device contacts depending on what app, device, etc. is being used. This becomes problematic when users working from outside the office are unable to contact the IT Service Desk, HR, or other internal services. To solve the problem, this article introduces a PowerShell script that will read a set of standard contacts from a CSV file and write them as personal contacts to user mailboxes. Mobile devices can then synchronize these contacts along with others created by the user.
