how to reset alowness to access data source

I have a Power App accessing SharePoint lists. The first time a new user is opening this app, a request appears to allow accessing the belonging sharepoint list. A user denied this reuqest. In consequenz the user receives no data from SharePoint. The user now needs to change his decission and want to allow the access to SharePoint. But where to change this? Any ideas?

Hi @Dirk_Prehn ,

I'm afraid there's no setting about resetting allowness to access data source currently. 

To reset this, you need to reopen this app.

Every time you run the app, the permission request will show at the beginning.

If it doesn't show, maybe your browser has remembered your choice.

In this situation, you need to clear your browser's cache, and reopen this app.

The permission request will show again.

@v-yutliu-msft ,thanks a lot for youre response.

Unfortunately this is not working. It seems not to be stored in any local cache.

I tried with a test user on different computers. So the personal "granted permission" seems to be stored some where centraly.

Where you able to figured this one out? I'm kind of running into the same issue, any suggestions?

Yes, I did. In my case the following worked


The user should do the following steps.

1. logon to power app

2. in left menu bar, go to Data and then to connections

3. delete the belonging sharepoint connection

4. open the power app, then the request message should appear again (if not try to reload the browser session CTRL + F5)


hope it helps
