Hi, 

i have tried for some time to send personalized emails to a number of persons. everything works fine, except that the emails are not sending :)

windows 8.1 on surface pro and office 2013 updated.

everything works fine, except that the emails are not sending :)

Hi Andrei,

Did you see any error messages when you try this? When you click "OK" on the "Merge to E-mail" dialog, did you see the message appears in the Outlook outbox?

Please elaborate a little bit on your question/symptom, so that it will be easy for us to help you.

Finally someone found the solution without any extra addins.

You have to change the key in the local machine registry (you need administrative rights for this).

I quote:

"I had this problem and solved it by changing HKLM\Software\Clients\Mail - Default to be "Microsoft Outlook" instead of "Windows Mail".

Even though HKCU\Software\Clients\Mail - Default said "Microsoft Outlook", I could not email mail merged documents as HTML unless I changed the HKLM key."

..instead of "every other mail program".

I had the same problem with Outlook 2013/Word 2013 32bit SP1.
