Outlook 2010 – The Operation Failed [SOLVED]
Thu, Feb 28, 2013When sending an email from Outlook 2010, I received the error “The Operation Failed“.
For me, this ended up simply being an issue with the email address autocomplete feature.
Solution:
I typed the first few letters of the recipient’s email address, pressed the down arrow on my keyboard, then pressed the Delete key. Then, I manually re-typed the recipient’s full email address, and my email sent without any problems.
