BC14 connection to Dynamics 365 (CRM) just stopped working

Posted on by Mpires 10

Hello,

Not sure if anything has changed in the last day or two but our connection from BC14 to Dynamics 365 CRM has stopped working.

It's been working fine for a few years and just stopped working on Thursday (07/04). The error we get when we try the 'test connection' is "Unable to login to Dynamics CRM". I have checked the login credentials and these are ok to login to CRM directly. Has anyone else had problems recently?

The connection was being made with Office, however I already tried with oAuth but it still gives the same error.


Thanks.
