Login window appears each time the files are opened

oHello everyone,

Various Excel files have been running automatically in our company for years. In all these files, various data sources are accessed in the background, the file is updated, saved and then closed again.

Since one of the last updates, however, we have noticed that the login window for authentication appears for the data source every time an update is started. In these cases, Power BI is always accessed here. The thing here is that it is not even necessary to enter a password, a simple click on the user name is sufficient. The update then continues as usual.

I installed an older version of Office for testing purposes (~ August 2023) and here no window appeared and the update went through immediately. So I strongly suspect that it has to do with a recent update.

Since these files run unattended at night, this logically leads to problems as no update can continue without account confirmation.

Is there a solution as to how we can suppress this required confirmation or bypass this window completely?

We have already done the following:

- Repaired Office

- Completely reinstalled Office

- Removed login information from the keychain in Windows

- Tested on other computers (unfortunately the same problem everywhere with the same version of Excel)

- Registration with Entra / Azure newly deposited

- Other account stored

Version used: Microsoft® Excel® for Microsoft 365 MSO (Version 2312 Build 16.0.17126.20126) 64 Bit

Unfortunately, all these steps were unsuccessful. Therefore I hope for a good tip from the community

Thank you very much already!

Best regards

Hi @ATFabi 

Does this issue occur on a specific data source in Power BI Service? Which data source does the Excel file refreshes data from? Do other data sources have the same issue?

In addition, I notice that a newer build 17126.20132 has been released on January 9, 2024. Would you mind install the latest build and check the refresh behavior again? 

Best Regards,
Jing

I have the exact same issue. Only PowerBI Datasets are causing the issue with forcing authentication.

Hello @v-jingzhan-msft 

This problem appears as soon as Power BI is accessed via Excel. We observe this behavior with all data sources within our BI.
