I’ve run into a base map issue with one specific Excel workbook linked to our ArcGIS Online web map. 
 
I keep getting an "The basemap is unavailable or has been deleted from the server." 
 
I am just using the default basemap's that are provided, so no custom base map.
 
It appears this issue started after I started writing formulas one sheet that reference the dynamic Attribute table I added into my excel from the ArcGIS for Excel add in.
 
I am not sure if that is the culprit, but it appears to have triggered the base map corruption. 
 
So far after extensive testing:
  1. What works:
    • Opening older saved versions of this same workbook loads the basemap normally.
    • Creating a brand-new Excel file and linking the identical web map also succeeds.
  2. What fails:
    • Only this one workbook immediately throws:
    •  
      Error code 3002: BasemapLoadError: Check the basemap service or select a different basemap.

    • Because the error fires on load, the Reset Map and Clear Cache buttons remain disabled, so I can’t clear the embedded cache.

  3. Actions tried so far:
    • Cleared the global add-in cache (%LOCALAPPDATA%\Microsoft\Office\16.0\Wef).
    • Extracted and removed Custom XML parts (/xl/webmap) from the .xlsx package.
    • Re-saved the web map in ArcGIS Online to ensure version compatibility.
Despite these steps, the basemap still fails to load and I can’t trigger an in-UI cache clear.

2 questions here.
 
1. Has anyone else seen this? I see a comment on one of @ShannonCardoza's blog post on the latest update to ArcGIS for Excel.
 
2. Has any one successfully used Excel formulas (e.g. VLOOKUP, INDEX/MATCH) to pull data from the ArcGIS for Excel dynamic attribute table into a different sheet?

Hey @DanielBettinger, Thank you for posting! I have created an issue for my tracking on this error message/workflow situation. My team and I will need to dig a bit deeper to see if there is something going on behind the scenes. Your testing and information is so helpful! Thank you!

Please stay tuned...I will provide updates here as I can. I also maybe reaching out again with follow up questions.
