MicrosoftHi JCOLLINS0331, you mention "organization". So, this means you got the Excel linking functionality to work in your own personal organization and but can't get them to work in your current organization? If so, you could consider asking your colleagues, in that organization, if they are having the same issue. This would point to , perhaps an Office 365 Admin setting that needs to be turned on. In Teams, restrictions can be applied to which SharePoint sites/Groups and content you get access to. So, opening an Excel workbook in a Teams tab does not necessarily give you access (via the linking) to other Excel workbooks. Though, that said, the error message, above, is perhaps an HTTP/Server caused error. That is, it is perhaps an intermittent error. Refreshing/quitting Teams can resolve that type of error.
Additional remediation, possible, is to recreate the links in the workbook or recreate a new worksheet in that workbook with the links or create a new workbook with the links in it.
You could, also, try reporting the issue in a support request to Microsoft. Give them that Error id. Use your own personal Microsoft work account to report the issue if you don't have access to the support reporting link in your organizational tenant.
Hope that helps.
