I added my Gmail account in my Window settings and that didn't work. I added my email to my Profile Preparer information that didn't work. I then tried under the Control Panel and my Gmail blocked this from happening. I do not use Outlook but when I try now a pop up wants me to log in to Microsoft Office 2010 which I have not done. This shouldn't be that difficult. Thanks for your help.
I send and receive PDF file attachments in my Gmail account all the time.
I don't send directly from my web browser. Instead, I use an free e-mail "Client" program called eM Client, which you can download here: https://www.emclient.com/page.aspx?contentid=homepage
