Hello there,

So here it is :
In my office we have 4 computers, with 4 different emails, 2 with GO Daddy and 2 with Microsoft ( we think ) . One of my coworkers has one of the emails that are not with go daddy ( [email protected]nf.sympatico.ca ) She receives many emails in a run of a day with no trouble, but lately, she's been having issues with two customers that email her PDFS - but when she gets the emails the attachments ( that are supposed to be PDFS ) show as winmail.dat files? She can't do anything with them, open, design, edit. etc. but yet if the same customer emails me the same file and same everything, I get the attachment as a PDF. ( I have GoDaddy email ) Is there a reason for this, and does it have to do with the receiver or the sender? Any help will suffice. Thanks for reading ! really looking forward to your suggestions :)

Kathleen

The customers are probably using Rich-Text Format in their Outlook emails, and this causes receiving mail clients to see the winmail.dat file. In addition, the PDFs are packed into that file and that's why they're not showing as attachments. Does your co-worker use a non-Outlook mail client?

-- Thanks for the fast response :)

They use Outlook on their desktop, me as well, But if the same customer sends us the same email with an attachment, I will get it as a PDF and she as a winmail.dat file.. :(

Are you all using the same client version of Outlook? If so, which one? 2007, 2010, 2013, 2016, 2019?

Could you check with your customer what they use for a mail client? I'm just trying to fit all the pieces of the puzzle together, and knowing what they use will be helpful.

It's curious this is affecting only 2010, but here's something to try: if you go to this page, copy the link to your customer, tell them to scroll down to Method 2, Outlook 2016, and then follow the instructions so they're sending a plain-text email only to your colleague who's having issues with the winmail.dat file.

After that, have them send an attachment to your colleague and see if it comes through properly. Please note from the instructions: they should not have your colleague in their Outlook Contacts list.
