When attempting to automate the upload of an excel email attachment when I attempt to change the name of the attachment I receive the "This workbook couldn't be opened because the file format may not be matching with the file extension." error.
If I use the attachment name control this error does not occur. Any ideas how to save an excel attachment to a sharepoint folder with a different name? I've looked extensively at the existing questions surrounding this issue out there but none address changing the name of the attachment.
