As of October 2022, Microsoft has disabled Basic Authentication* on their applications and is now forcing users to use Modern Authentication. This sudden change may have thrown a wrench into mail fetching in your ServiceDesk Plus instance. However, with just a few simple changes in your configuration, your service will be back up and running. Read on to find out how you can fix your ServiceDesk Plus mail with Modern Authentication.

First, you’ll need to go to your mail server settings in your instance. When you do this, you may be greeted with a screen that looks like this:

Just click on “Switch and Configure” on the top right, and you’ll be greeted by a simpler setup for your mail server. This is the first step in fixing your ServiceDesk Plus mail with Modern Authentication.
If you have an Office 365 or Outlook account, you can configure that by going into the mail server settings in ServiceDesk Plus and choosing which mailbox service you’re using.


After successfully logging in to your Microsoft account, you will have your mailbox made with modern authentication enabled.
Alternatively, you can use the native mail service that ServiceDesk Plus Cloud offers.

To set an email domain more suited to your organisation go to “Mail Addresses” in “Mail Settings.”


Once you got your domain sorted you can change the reply-to-address and your mail server is good to go.
