403 error Allow Origin. - Powerapp connection azure table

Some of our O365 users get an 403: no 'access-control-allow-origin' header when the app tries to retrieve values from an azure table. Can't figure out the reason. Anyone simular experiences?

The users accepting the O365 user and SQL connection in the dialog. The app shows the O365 user results, not the values from the azure table. Furthermore I have the impression when this has gone wrong once for users, this also implies that they get the same error when connecting from an other app, pointing to the same table (also accepting, again, the connection in teh dialog)

Re: 403 error Allow Origin. - Powerapp connection azure table

Hi @kruismanp,


Have you configured the SQL server connection Share Page?

The user who use the App with SQL server connection, would need to have the proper access configured with the SQL server connection:

Share app resources

If issue still insists, please share the Session ID under PowerApps with the problematic Account, session ID could be found under:

Account->Diagnostics->Session Details

Re: 403 error Allow Origin. - Powerapp connection azure table

Hi Michael,


Yes we did: synced ad group. If we use certain ad groups this access has the allow-origin error

For now.. we have the complete organization  granted access (to app and azure connection). This works.


W’ll do some more testing next week. Probably this reveils that we only messed up the/ a configuration?


Thanks for the response
