Outlook Has Defeated Me, At Least For Now

Somewhere in the hidden depths of Outlook is a hidden file for a recipient. This file is not letting me send an HTML file to this recipient.

I thought I had fixed it, because the fix worked for a bit. Then it reverted back to refusing to let me send HTML to that one person.

Searches show that the auto-complete cache can cause an issue like this,  I have deleted the auto-complete cache (more than once). I have removed the recipient’s email and added it back numerous times, all to no avail.

I downloaded and installed a utility to clear the auto-complete cache .

Didn’t work.

I created a new Outlook profile, still didn’t work.

Every search told me to check the properties by right clicking recipient’s email address, but there are no options for properties in the email address. All that shows up are these options:

No Properties.

Someone said to right click on the email address in a message. I did get 'Properties' so clicked properties and got the original form with the recipient's name and email address and nothing else.

So somewhere lurking in my Outlook there is a ‘Property’ that tells Outlook to send emails to this recipient’s address as RTF instead of HTML.

I usually keep  trying to fix problems until I succeed, but so far after almost 10 days I am not having any success.

But, I keep trying!
