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.

    The first time this happened to me I had copied content from an Illustrator PDF file into my Word document. Trying to send via mail merge gave the error. Removing formatting and recreating the file in Word fixed the problem.

    The second time this happened to me, I had copied the contents of a Google doc into my Word file and received the "cannot send" error message when trying to Mail Merge as HTML. Upon inspection of the Word file, all of my type was formatted with normal fonts, but if I placed the cursor on blank lines in between paragraphs, the font showed as

    "-webkit-standard"

    Selecting all the blank lines and changing the font to something else fixed the problem. I was able to do mail merge with HTML after that.
