winmail.dat

I just started having this problem when I updated my Windows version from XP to 7. My Outlook 2010 remains the same, and is set on HTML when sending email. Despite that, now PDF and Office files (.docx, .xlsx) are all coming through as Winmail.dat files. When I am sending them to myself so I can have them on the iPad, they are still arriving at the iPad as Winmail.dat, despite my Outlook settings being set to send everything HTML.

It's probably because they've been sent from Outlook in rich text format, as opposed to plain text or HTML (winmail.dat files). If you can't get them resent in text or HTML then there are a few apps in the store that might be able to read them (search for winmail)

You are welcome. If the document is only one page it is embodied in the email and you can get the prompts for saving it by pressing down in the middle of it. If multi-paged then it shows as an icon and you already know how to open/save it.

Hi,

You do not have to modify anything from a Mac.

Microsoft has already fixed this issue.

People familiar with Exchange will be able to disable TNEF format.

This format is used by Exchange and Outlook in sending mails but this format is not supported yet by Mail or Thunderbird. Administrators of Exchange will have to disable TNEF format on their domains with PowerShell commands. If you receive winmail.bat, ask administrators from the sending domain to disable TNEF.

Hope it helps,

Hey Guys,

I'm a new user of iPhone, switch from Android. I just bought iPhone 5, and was receiving email fine but this email that i received was in winmail.dat.

I've checked with sender, it was sent with HTML format. My other colleagues using iPhone can view the email content without problem but why can't I view?

Can anyone help me?

Thank you

Sam

I was having problems receiving PDF attachments in e-mail on my iPhone 5 with iOS 6.0.2. They would arrive as winmail.dat files.

I had one of the e-mail senders delete my contact information in their Outlook address book and the problem was fixed for any new e-mails (not the previous emails).

I saw this solution over in the OS X forum.

None of these solutions make any sense. I sent myself a pdf document because Im told its the only way to get it onto the iPad. The email shows up with the pdf document on my regular computer but shows up as a .dat file on the Apple ipad. Defies all reason. All Im trying to do is move documents to the tablet but Ive spent more time trying to figure out how .... Its ridiculous. I cant believe anyone ever gets any work done on these things!

Bvjed,

Last year there was a security problem with PDF documents and it took Adobe several months to provide a solution to the issue.

Microsoft some-what over-reacted to its customers' request for a work-around and supplied a "hack" to Outlook Exchange servers that blocked the transmission of PDF documents. Unfortunately this "hack" essentially corrupted email addresses and permanately caused them to block PDF documents.

The only fix is to delete any email addresses that were created during that period from contact-address-books and use the current email address. In your case, it sounds like you need to delete all old-versions of your email addresses from whatever locations you can find on you personal computers.

Unfortunately, you may be exchanging correspondence with indidviduals who have stored corrupted versions of your email address in their own email address systems. You would need to contact them and ask them to delete these old references.

This is an old issue that is not seen very often now. Almost all Microsoft Exchange servers no longer have this problem. Hopefully you are not exchanging emails with someone using an out-of-date Microsoft Exchange server.

My I suggest my productLetter Opener Mobile for iPhones and iPads to open winmail.dat attachments.

Bvjed et al.

My wife has just had this issue and after digging around I found what was causing HER issue.

Situation:

Some email recipients were receiving a .pdf file as a winmail.dat file but this was not everyone and only affected those on iPad/iPhone that could not receive/interpret RTF formatted emails. Anyone opening the email on a Windows PC (and I haven't tested on Mac or other devices such as Android etc) would see the .pdf attachment and it would open normally.

Analysis:

There are plenty of advise/recommendations saying that .pdf files attached to emails formatted in RTF format may not be able to be received if the receiving client cannot handle RTF. HOWEVER, it is important to understand HOW emails are converted/formatted in RTF by Outlook (various versions). One method that most users have checked is the Mail Format setting within each email as either HTML, Rich Text or Plain Text. The other method that is much less obvious is the setting at each email address level and you can check this by right-clicking on the recipient's email address and selecting Outlook Properties. Assuming you do not have the person's contact details in a contact record, it will show a small Email Properties window. Note the last field called Internet Format and if it states "Send using Outlook Rich Text Format" then that recipient would be unable to open .pdf attachments that you send them if they are using an IOS mobile device.

Solution:

Change this value to "Let Outlook decide the best sending format" and send the email & attachment again.

This explains why some people found the solution to be deleting the entry from their Outlook Contacts - it someone reinstated the format option to the "Send using Outlook Rich Text Format" for future emails. How that happens is for someone else to determine! ;-)

Please like this if it helps you.
