Hi,

We are using the POP3 Adapter in BizTalk Server 2020 for Polling email from Exchange Online(Office365) Mail Server.

Microsoft given the statement in the below site and saying that "Starting on October 1, 2022, Microsoft is starting to disable an outdated way of logging into Exchange Online known as 'basic authentication', Exchange Online starting January 2023 when we permanently disable basic authentication".

https://techcommunity.microsoft.com/t5/exchange-team-blog/exchange-online-email-applications-stopped-signing-in-or-keep/ba-p/3641943

Based on the above statement, The BizTalk POP3 adapter Basic Authentication also will impact?

The above site suggesting to move OAuth modern authentication but in BizTalk POP3 adapter is not having the OAuth Authentication Scheme.

All we tried to change the Authentication Scheme from Basic to SPA and Digest but we are getting the below error.

SPA:
The adapter "POP3" raised an error message. Details "The POP3 server does not support the specified authentication scheme.
Please change the scheme to the one supported by POP3 server.
URL: POP3://outlook.office365.com
Scheme: SPA
Error: -ERR Protocol error. 14 ".

Digest:
The adapter "POP3" raised an error message. Details "The POP3 adapter could not authenticate using the supplied credentials.
Please change the scheme and supplied credentials.
URL: POP3://outlook.office365.com
Error: +OK The Microsoft Exchange POP3 Service is ready.

Could you please help to assist on this issue and possible way of implement OAuth for the POP3 Adapter in BizTalk.

Regards,
Devanand Sekar

    Yes, POP3 is affected. BizTalk will need to move to an Oauth/Modern Authentication method for this to work.

    Yes, BizTalk will need to support creating an application in Azure to authenticate with POP. You probably need to talk to their support
