You connected the Lansweeper Helpdesk to your O365 mailbox using a login and password. All was working fine yesterday, but suddenly you are having issues connecting, or your mailing service in the Lansweeper helpdesk is no longer working correctly. 

What went wrong?

Effective October 1, 2022, Microsoft has started disabling Basic Authentication for Outlook, EWS, RPS, POP, IMAP, and EAS protocols in Exchange Online, for all tenants.

How to solve it?

Make sure you have created a Microsoft Cloud Services application for scanning and email. Once you have set up the application, you will have to add permissions to the Microsoft Graph application to send and receive emails before you configure (or edit) your email account in the helpdesk email configuration section.

Still stuck?

We suggest navigating to Program Files (x86)\Lansweeper\Tools and using the MailTester.exe tool. The mail tester will provide information about your possible issue. If you are able to connect through the tool, apply the same settings used in the mail tester in the Lansweeper helpdesk e-mail settings. 

Some users have mentioned issues after implementing MS Graph by just editing the existing mail configuration. The recommendation is to remove the current configuration and implement it again once you have followed the steps in the two articles above.
