Word will no longer mail merge documents to email in HTML format (fails with message "Word was unable to mail your document" and "Word could not finish merging these documents or inserting this database").  However Word successfully mail merges documents as text.

Mail merging of HTML documents has worked for many years but seems to be broken in the latest update of Office for Mac

Details:

Word V 16.8 (171210)

Outlook V16.8 (171210)

Existing Profile

Data source: Word Document

Fails on new document with one merge field only (nothing special)

Microsoft 365 and Office | Word | For home | Windows

Thanks @LindsayLindsay 

It seems changing the font does affect it.  We failing with Caibri, but changing to Cambria seems to make it work.

Thanks for this!

It solved my problem - it's stupid that changing the font from calibri to calibri light solves the problem - Microsoft what are you guys doing?????!!!!

FYI I'm running word 16.18

Great solution!!! It worked for me aswell !!! 

If the Word font is Calibri... "Word was unable to mail your document" error message, and no email is being sent. 

But if changing to Cambria, it works again, sending with html format. 

But..... why should it not work depending on the word font? It's a bug, even considering that on previous version worked fine. 

Please review and amend this bug.

I'm hoping this helps someone...

Not being able to send HTML emails via mail merge seemed to be caused by the document's font not be tagged as (Body).

When the font was set to Calibri (Body) in Word, the mail merge worked.

When the font was set to Arial, the mail merge did not work, and I got the "Word was unable to mail your document" error that others have gotten.

The HTML DOM has the tags <body></body> -- these are the main tags that house content in an HTML document.  This may factor into the DOCX-->HTML conversion process...

I can confirm I was having the same problem and the font change fixed the problem.

I opened the document, 'Removed the Headers' and once opened, SELECT ALL, change the fonts, saved it, and relinked the document to the original Excel file.

Once this was done, I was able to SELECT ALL, change the font back, and save the document, and the links maintained and the issue doesn't occur again.

I would suggest that you make sure you have selected the entire word document when you change fonts.   

 Looking at the success & failure modes, it seems to be simply the inability of the merge to parse the HTML document.  By selecting the entire document and changing the font you are essentially rewriting the document in an updated format.  This is a guess since I can only look at the success & failure modes reported and can't run any true debug.

    I spent three hours debugging this problem as well.

    I had a 2-page Word file that was giving me the "cannot send" message when using HTML.

    The post saying that changing the font helped someone clued me in that perhaps the Microsoft software is having problems with certain ASCII characters, likely invisible ones.

    Changing the font was not an option for me because I need to use our company fonts for correspondence.

    I delete the second page of the 2-page letter and was able to send the first page, so I knew the problem was in the second page.

    That page had been created by copy/pasting the contents of a PDF file into Word (since Mail Merge on Mac does not support attachments).  I concluded there must be some unseen content that was causing the error.

    So I copied the text into e-mail and then copied that back into Word using "Paste and Match Style" to remove formatting.  

    That was able to send without any errors.

    Then, I slowly (painfully) had to rebuild the styling of the document, checking periodically to see if the new font or bullet characters were causing an error. I was able to rebuild and send the 2-page document after this long, arduous process.

    Hope this helps others.
