Cracked it, it's a mix of other peoples solutions. Not sure who is at fault.
Solution that worked for me...
1.. Start an eMail... (I guess Auto complete is on), and you are typing a few letters and sellecting the name.
2.. Start the auto complete, and scrol down to the name that is recieving the winfile.dat file.
3.. Hit the "X" to delete the name.
4.. Close down Outlook.
5.. Restart Outlook, and start again the new eMail (and check that the name is nolonger in the list).
6.. From the iPhone that is recieveing the unwanted Winfile.dat format, have that person send you an eMail.
7.. Once recieved in Outlook, reply back with an attachment.
8.. On the iPhone, check that the file is nolonger a winfile.dat.
I also found that the other winfile.dat's where now also coinverted.
No finger pointing, just happy that this works... for me at least.
Thanks to all those out there that contributed, including Dave Hutch, who set me off on this path.
I have been frustrated by a sudden upsurge in receiving the winmail.dat file types. There are many discussion about what a winmail.dat file is, who's to blame (sender/recipient) etc.
Here is the relevant info: Winmail.dat files (and I believe most dot DAT files received from outlook mail) are of file type T-NEF, you could look it up.
Here is a relatively simple FREE solution: Download the opensource tnefDD. It works, it's simple (I keep the tiny tnefDD.app on my dock and simply drag and drop the winmail.dat file onto it. A window opens showing all the files in the dot dat file. Drag em to the desktop et voila!
For reference, I found the tnefDD app link and a lovely article on the problem here. Very helpful.
Guys, I think I have just solved it.. After almost giving up and switching over to Samsung due to all Apple's "work around" issues...
- Go to Outlook: "Tools" (Toolbar), "Options" and then "Mail Format" tab.
- Under the header "HTML format" there are 3 tick boxes.
- The first tick box says "Reduce the file size of the message by removing formatting information that is not necessary to display the email message"
- You need to UN-TICK this box.
It worked instantly for me... Didn't have to do all the things previously mentioned in all of the discussions and suggestions.
I am running Outlook 2007 - Unfortunately I did not test it in any other 3 party email app, but there should be similar settings?!?
Try it out, hope it works for you too... All the best!
