Laravel Microsoft Graph Mail driver - Mail Driver for Office365

Mail driver for the Laravel framework to send emails using Microsoft Graph without user authentication and SMTP. Only specify the E-Mail-Address in the FROM-Header of the E-Mail and this Office 365 Package will send the E-Mail trough the Microsoft Graph-Api and put the sent E-Mail in the sender's Mailbox sent folder.

Key features:

• Send E-Mails with the Microsoft Graph-Api instead of the SMTP driver
• Automatically puts the E-Mail in the Sent folder of the user in the From-Header
• One Application per Organization
• Supports multiple Domains
• Supports large file attachments
• Faster and Error-less than the Office-365 SMTP
