IPhone receives Winmail.dat
Hi
A user receives winmail.dat attachment when sending an email containing a PDF attachment to herself from Outlook 2016
Outlook is set to send emails as HTML
If she transfers an email already containing a PDF file the received email on the iphone correctly contains the PDF attachment
Any ideas ?
Thanks
Yann

Bizzarely the same email sent to my iPhone arrives correctly, PDF included
Her Outlook is configured with an Imap ISP email account; no Exchange here

OK .. then I'd focus on the AutoComplete contacts on HER outlook .. item 3 in my posting. Outlined in more detail in the URL I posted also
Right click AutoComplete contacts on HER outlook and select Properties and in Internet format field select "Let's Outlook decide" in the pull down menu.
The better way is to ask her to create a contact for every receipent instead of relying on the AutoComplete or Suggested contacts.

However, the above workaround is only feasible if you can manage the sender to change his or her settings in MS Outlook.
For most of the times, you can do nothing to ask the sender to change anything and the only option is to install an app like the one below.

The user is back at her office and I was able to run another test
I modified the properties for her contact, by specifying that mail format should be in text mode
I then sent her an email with PDF attachment and this was again received as winmail.dat
The email was apparently received as text because she confirmed that her company logo wasn't present in the received email

ASKER CERTIFIED SOLUTION

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
There are plenty of explanations but basically Outlook and Exchange use a method of encoding attachments that not all other email clients can parse properly and OSX Mail is one of them
Solutions range from
1. Using Plain Text formatting in the email not HTML or RTF sometime can resolve it.
2. Change sending settings on Outlook for Windows on a per contact or overall settings basis
3. Changing the autocomplete email which may be defaulting to RTF even though you're sending HTML format
Remove the Autocomplete entries for the specific address(es) using NK2Edit.
Added email addresses to Contacts as new entries (Not Suggested Contacts).
4. Manage TNEF formatting at a server level depending on what mail server you're using
