I faced an issue: “Access is denied. Check credentials and try again” when trying to get an email message from M365 using “Get email message DAC”.

This issue happened with the latest version of Nintex RPA 23.11.1. When I tested it with version 22.9.3 with the same configuration as the latest version (Dynamic Command version is 22.9.03.05.23), no error was found, and the messages could be retrieved.

The different between Dynamic Commands 23.11.0.1 with 22.9.03.05.23, no server field exists like on IMAP or POP3.

Is there any way to solve the issue?

FYI, I did followed the step by steps Working with M365 Exchange Modern Authentication configuration (https://help.nintex.com/en-US/kryonrpa/23.11/Content/Console/WorkingwithMicrosoft365ExchangeModernAuthentication/Azure_Configuration_for_Modern_Authentication.htm?tocpath=Studio%7CCredentials%20Vault%7CWorking%20with%20Microsoft%20365%20Exchange%20Modern%20Authentication%7C_____1)

Appreciate if anyone could have any input or suggestion to solve this issue.

The issue above is not just applied to Office365 but also with Outlook.com using IMAP configuration. The difference with Outlook.com was I had created an app password (legacy and not using modern authentication) but still yet failed. It said “Invalid Credential”. Does anyone have the same issues as mine?

FYI, this issue happened only with Microsoft email and not with other email providers like Google and Yahoo.
