BC 18 Edit in Excel Invalid server configuration

bokuvka

Hi guys, please can you help me with issue - Excel Addin for BC 18 is not working.

Customer has OnPrem BC 18 installation with AAD auth enabled.
Users reported me, that Edit in Excel function stopped working but they did not use it much.

I inspected app registration, ODATA are working, SSL is enabled. Everything is done as documentation says.

Error message:
Invalid server configuration

Details:
No authentication resource id is defined



I asked my colleagues about help and I was told, that they are experiencing similar issue on their BC 18 installations.

Thank you in advance.
Martin.
