Hi @Harentsoa RANDRIAMAHOLIMANANA

Thank you for posting your query on Microsoft Q&A.

It is likely that your organization has IMAP blocked, as this is considered a legacy protocol and it is encouraged to keep it disabled.

Also if your account uses MFA it is not possible to complete this when using IMAP so it will always fail.

I would suggest to use a webmail solution which supports modern authentication, or else you would need to modify your Exchange Online mailbox to allow IMAP and bypass MFA. We have some details on this here - https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/pop3-and-imap4/pop3-and-imap4

Let me know if you have any further queries, I would be happy to help.

Hi @Harentsoa RANDRIAMAHOLIMANANA You're welcome! No, unless you have disabled MFA and allowed legacy protocols, which is not recommended, then it will not work.

Hello @Domooney-MSFT
Thanks for your responses
My questions is about the uri_redirection in the application in azure
I have a webmail hosted locally on localhost using laragon and nginx, so i added this as the redirection_uri :
http://localhost:8181/roundcube/?_task=mail&_mbox=INBOX

the OAUTH successfully work because i got 'Success Operation' in the connexion journal of azure which means that the oauth2 request is done

But i cannot access to the http://localhost:8181/roundcube/?_task=mail&_mbox=INBOX where the mailBOX of the users is and i keep being redirected to the login page of roundcube with the error 'Session invalide or expired'

SO about the URI, it should be an 'https' or no??
The http://localhost is the cause for non accessing to the mailBOX or not ?

Hi @Harentsoa RANDRIAMAHOLIMANANA

If you are using OAUTH then that should be fine, also using http for localhost is supported. But you can try using the local IP as it can work in some situations where localhost fails.

We have details on this here - https://learn.microsoft.com/en-us/entra/identity-platform/reply-url#localhost-exceptions

And guide on using local IP here - https://learn.microsoft.com/en-us/entra/identity-platform/reference-app-manifest#replyurlswithtype-attribute

Kind Regards,

Donal
