Excel worksheet using Power BI data model triggers com error

[royce4]

Hi,

I have a colleague who has an Excel workbook that connects to a data set in the Power Bi service and he gets an error now when connecting to it. He has connected to it before maybe around a month ago without getting an error. He has a Fabric license and has Admin permissions for the workspace the datasets reside it- in fact he created them.

COM error: COM error: Microsoft.AnalysisServces.AzureClient, Can't obtain the account information for <<email address>> while trying to refresh the token. 

I have little experience using Excel to connect to Power Bi datasets so this 'token' error seems a bit unusual. 
Would this something that can be resolved by editing the data source permissions in Excel- like re-entering them?
Or is this more a different issue?
I have not found any similar issues around this error message. 

Looking for any advice.

Thanks in advance.

Hi @royce4,

Thank you for reaching out to the Fabric support forum with your query regarding the COM error encountered when connecting your Excel workbook to a Power BI dataset. I understand how frustrating this issue can be, especially since it was working fine a month ago. 

• Open Excel and navigate to File > Account. Click Sign Out, close Excel completely, then reopen it. Sign in again and attempt to reconnect. 
• Please sign in to Power BI Service and attempt to open the dataset directly. If you encounter any issues, it is likely an account-related problem rather than an Excel-specific one.     
• Navigate to the Power BI workspace where the dataset is stored and verify that you still hold the admin role for the workspace. Ensure that your Power BI license is active and that your organization’s subscription has not expired. 
• Remove & Re-add the Dataset Connection in Excel, navigate to Data > Queries & Connections > Manage Data Model. Remove the current Power BI dataset connection and reconnect through Get Data > Power BI Datasets. Go to Data > Get Data > Data Source Settings, locate the Power BI data source, select Edit Permissions, and re-enter your credentials. 
• Verify if the authentication token has expired.  
• Some organizations restrict logins based on device, location, or security settings. Please consult your IT administrator to ensure your access is not restricted. Check Multi-Factor Authentication (MFA). If MFA is enabled, ensure Excel supports it and verify if your organization requires an app password. Contact IT if you suspect MFA settings are blocking the connection.

Hi @royce4 , It seems to be like authentication error could you try going to data source settings andclear them and login once more and try connecting to dataset ..... If the issue is still there try confirming if the user has access towards the file now also or it has been removed
If this post helped please do give a kudos and accept this as a solution
Thanks In Advance
