Hello All Experts,

I am getting below error while trying to configure crm using configuration wizard with outlook.

"Cannot connect to Microsoft dynamics 365 server because we cannot authenticate your credentials.

Check your connection or contact your administrator for more help".

outlook addin version :- 8.2.0002.0137

although the same version is getting connected to the CRM.

    Are  the two workstations on the same Network?  Was the network connection setup exactly the same.

    Depending on how it is setup and a few other things, they could or could not be using the same port for ADFS and HTTPS.  I have seen where IPv6 being checked caused issues even though there was nothing using that as well as several other quirky network issues.  Without seeing the workstation configuration, it is hard to say.  You didn't tell us what the network change was but if that is truly the only thing that changed, then it could be in whatever changed.

    Hello Beth,

    if that is the case then , why it has worked on my side when connecting to the client network.

    also i didn't understand difference of ports and https authentication, because https also uses the port correct?

    What network change was made?  Could be the ports are blocked that need to do the ADFS authentication where using the web uses the HTTPS.

    Hello Andy Ran,

    For your comment.

    we are able to login using web client on the same machine and with the same credentials.

    but now i have got comment from the user that it's working now , only the difference was network change.

    but when i am trying at my machine with the clients network then also it's working with my credentials.

    what could be the issue behind this , still i am clueless.

    any other thing which we can apply for this.

    In the same machine, through the web browser, if you use same credential to log into web client, would the similar error happen or not?
