Mail Server Settings

8 minutes to read

Once the administrator creates an account for the users, Access Manager Plus sends email notifications to users with their account details. The email sent from Access Manager Plus will serve as both a notification and contain vital information such as access URL and credentials for login. Hence, it is essential to configure mail server settings in Access Manager Plus before adding users. Access Manager allows you to configure the SMTP mail server used in your environment or an external mail server - Microsoft Exchange Online, that permits OAuth 2.0 authentication for all emails sent from Access Manager Plus.

The following sections will help you to learn about configuring different mail server settings in Access Manager Plus.

  1. Configuring Microsoft Exchange Online as the mail server
  2. Configuring other mail servers
