Excel 03 file will not open in Excel 2007
Posted on 2008-10-09
Latley we have been having problems with excel files. We are getting .xls files via e-mail and some users who have Office 2007 Standard on an XP Pro PC try to open the file and get the following message:
The file you are trying to open, 'filename.xls' , is in a different format than specified by the file extension. verify the file is not corrupt and is from a trusted source before opening the file. Do you want to open the file now? "Yes, No or Help". If you click on "Yes, it opens excel but the workbook is blank. If you click "no", it closes. and "help" was of no help at all.
However if a user who has Vista Business and Office 2007 standard, they can open the file. Then they save the file and send it back to the user who has the problems and they can then open it.
If you save the file to a local drive or network drive, it is blank "0 KB". I searched the internet and only found how to stop the "yes, no, help" popup.
We use Excahnge 2003 internally.
Any ideas why this is happening?
