Second Dynamics connection - can't create with different user

I'm trying to make a second Dynamics 365 connection using a service account. I'm unable to do so, as it keeps reverting to my user in the login process.


I have one Dynamics 365 connection as

I want to connect to a second D365 CRM instance as


When I click Add a connection and select Dynamics 365, I'm taken to the login window, but it usually automatically runs through and logs me in as without giving me a change to change login email. 


Sometimes it will give me the option to change login email, and I'll use the credentials, but when the login window closes, it shows me a new Dynamics connection to

Note: this has been resolved at some point in last couple months. Have since been able to create a service account connection and see both connections in my connections list.

You should be able to do that by re-authenticating from the portal.


Click on the connection of interest and then click on Auth and you should be able to authenticate with different credentials.




Hope this helps




Have tried this multiple times. It keeps reverting back to my user connection (

selecting cc*** logs me in

The account should actually be changed, it's just that the "connection name" still has the original account address. Can you please try to access the data source and see if you can see the correct data?


We're tracking this isue from our end to try to improve the user experience when changing the credentials of a connection.

The data source is continuing to use my credentials, and not that of the service account (SA). I'm not able to load the tables from the instances that are available to the SA but not available to me.


Also note, when I click into the connection for more details, it still shows owner as me, not as the SA.

Hi michowl,


It is really an odd issue. I've got an O365 Enterprise E3 trail and I got exactly the same issue like yours. I just checked an Dynamic 365 connection using another organization account that I created a long time ago, it used to work but now it won't show the dataset.




First 2 connections used the same account as I'm using on this PowerApps, but the highlighted connection used another account, no dataset shows.


Now I cannot create a new connection using another account.


But my colleague who has another E3 plan got this works successfully. He has no problem creating another connection using a different org account.

@michowl, thanks for reporting this issue. I can reproduce it as well and I'm trying to report it internally.

I am having a similar problem.  Attempting to make a connection to O365 using different credentials in order to access a shared calendar.  Authentication proceeds but uses my credentials rather than the alternative.  Complicating factor:  I use VMware Workspace One for authentication to O365.
