Deprecation of basic authentication in Microsoft Exchange Online

Deprecation of basic authentication in Microsoft Exchange Online

Dear users,

As you maybe aware, Microsoft has announced that it will start disabling basic authentication for Outlook, EWS, POP, IMAP, EAS, and RPS protocols in its Exchange Online effective October 1, 2022.

The alternative, Modern authentication (OAuth 2.0 token-based authorization) has numerous benefits including security and improvements that help mitigate the issues in basic authentication.

We strongly recommend our customers to switch to modern authentication at the earliest to avoid any disruption with mail processing in ServiceDesk Plus MSP. Refer to the following article to configure OAuth in ServiceDesk Plus MSP.

Should you have any questions, write an email to

PS : If any user faces authentication failure or Mail fetching issue in our application . Please reconfigure the mail settings as mentioned above (move to Oauth) and check the case.
