Workbook (Logon failure issue) : cells for .Net


var excelWorkbook = new

With above statement I am getting below exception . we are using cells for .Net

Exception Type: System.IO.IOException
Message: Logon failure: unknown user name or bad password.

Please let know whats creating this exception.


Please make sure that you are specifying valid Excel file path (for “fullFilePath” variable that should refer to disk on the system and you should have sufficient rights (e.g admin rights) for the application to access/ read the file in the folder) while opening the Workbook. If you still could not evaluate, kindly provide your template file here, we will check your issue soon.

Thank you.
