Change confusing error message (corrupt file or file format not supported)
One of the operational Excel workbooks cannot be opened in Excel Online, on the opening attempt the following error message is received:
We’re sorry, we couldn’t open you’re your workbook. It’s possibly corrupt or using a file format that’s not supported.
Do you want to try and open this file in Excel.
However when the file is opened and inspected in the Excel reach client no corruption is detected.
The file contains External Links that are not supported (i.e. cannot be resolved) in Excel Online. After removing the "unresolvable" links, the file can perfectly be opened in Excel Online.
The error message should be changed in order to make clear to the end users what the real problem is.
