Outlook connector issue

Dear all,


I'm currently having and issue with one App I have been developing. Somehow it has created a connection with Outlook (not O365, just normal Outlook). I really haven't such connection. I did though made a connection with Outlook365 just yesterday. So, I'm affraid it might be related, but I don't know how.

I have shared the app with some colleagues and they are have tried to use the app using a desktop web-browser.


The problem is when they try to open the app, it requires them to sing-in Outlook (it also requires other authorization such a SharePoint and Outlook 365, which are automatically signed-in, so no problem on it). When they try to sign-in they get a notification that their account doesn't exist, that outlook connection only accept individual accounts.


You can see it doesn't make sens they need to use any individual MS account to use a company app.


I went inside the app editor and find the connector. I deleted the connector "Outlook" leaving still there Outlook 365. Still the app keeps asking to sign-in Outlook. And now, even for edition, I get that request. Fortunately as owner I can reject that request and still edit the app, but the end users they are kicked-out from the app if they don't sign-in Outlook.


I haven't try to remove the Outlook 365 connection as so far that it doesn't seems to bring problems, and I actually want to keep it for future development on the app.


I hope some of you can help on this. I really don't know how to move forward, meanwhile the app is unusable.

Hi @Anonymous ,

Based on the issue that you mentioned, I suppose that you created a connection to connector rather than Office 365 Outlook connector.


The user @Msiadmin has faced similar issue with you, please check my response within the following thread:


When you create a connection to connector, you should sign in with your personal Outlook account (personal Microsoft Account) rather than Office 365 account (Azure Microsoft Work or School Account).

Please check the following article for more details:

Hi @Anonymous ,

Have you taken a try to remove the connection from your canvas app?


On your side, you should take a try to remove the connection from your canvas app as below:


then re-publish your app, then run your app again, check if the issue is fixed.

That connection doesn't exist. Just in case I saved and re-publish the app. The app is still requesting the users to log-in with a personal account. If the users reject, the app kick them out from the app.


Do you know about any other solution?




I'm having the same issue. 


Using Office 365 connector, no connector in the app/flow.
When I or my users attempt to launch/edit the app, it prompts for connector log-in.
I even went into the global connectors, and deleted the connector.  It does not exist in our instance (as far as I can see).

Save/publish app, still getting log-in prompt. Absolute blocker on this project.

I'm experiencing the same problem! The Outlook connector doesn't exist in my app project, but somehow, the published app ask the user to sign in to Outlook as one required connection.


Then user tried to use company email account to sign in, then it will prompt them "Microsoft account doesn't exist" since Outlook expects a personal account.


It is not only annoying, but users now can't use the App at all.


Any help please!!

I had this issue too and I was able to resolve this by exporting the app as a zip package, opening up the app json file and deleting the connectors reference (it was still in there). I saved it app, re-zipped and imported and it worked 

To provide an update, I found out there is a embedded flow in my app which requires the Outlook connection. After removing that flow (since it is no longer needed), the app doesn't require Outlook connection anymore.

Was it a flow reference or something else, I am looking in the references\DataSources.json file and I do not see the outlook connector, is it in another file? And what does it look like?
