I have recently installed Office 2010 on a new Windows 8 based laptop.
In Excel 2010, when I try to email a workbook as an attachment I get the error message:
"Could not complete the operation because the service provider does not support it."
I had the new iCloud app installed to sync with Apple's iCloud but deleted and disabled all Apple links to Outlook. I deleted all iCloud .pst files. The problem persisted.
I do not get this error message when I email attachments inside of Outlook2010.
Any suggestions as to why Excel will not email files using the attachment feature but Outlook has no problems?
