E-mail Issues w/ Help Desk

[RobDz]

Hello all

Recently we obtained a full license for LS and in turn, moved off of our test platform. We cloned that test system (VM), renamed the server name and it seems since then, we are encountering authentication issues with the e-mail account we use for the help desk. No matter what e-mail account is used, we receive a "incoming mail error: Login error" message. We can verify this O365 account is fine by logging into OWA without issues.

I've removed all other references to the previous named server within the LS config pages as well.

Has anyone encountered a similar issue? Is there a possible issue with the SQL DB ?

LS version is currently at 10.2.5.0

Hello there!

Microsoft is removing the ability to use Basic authentication in Exchange Online for Exchange ActiveSync (EAS), POP, IMAP, Remote PowerShell, Exchange Web Services (EWS), Offline Address Book (OAB), Outlook for Windows, and Mac. They are also disabling SMTP AUTH in all tenants in which it's not being used.

This decision requires customers to move from apps that use basic authentication to apps that use Modern authentication. Modern authentication (OAuth 2.0 token-based authorization) has many benefits and improvements that help mitigate the issues in basic authentication.

For Lansweeper, to use an O365 email account to send or receive emails in Lansweeper, make sure that:

• You've already set up your Microsoft Cloud Services application.
• You're in possession of your Microsoft Cloud Services application's Application (client) ID, Directory (tenant) ID, and Client secret.
