    What is the winmail.dat at the bottom of BES messages?

    Advertisement



    I switched over to a hosted BES from BIS and now at the bottom of my outgoing items I have a winmail.dat file attached instead of my "Sent from Blackberry Device" message. I would rather have the BIS message back instead. What is the .dat file and how can I fix this?
    Thanks gang.

    Do you have BES through Microsoft exchange?
    Winmail.dat is usually screwy thing that hapens with attachments when using outlook or express mail.
    Check with your administrator about changing your signature.

    This is with sending messages from my device alone... Not even from my computer at all. Yes it is through Exchange though.
    Thanks.

    Even if you send your message from your phone it has to go through exchange server, at that point server is probably attaching vcard to your email.
    However, exchange messing vcard and converts it to winmail.dat.
    If you find winmail.dat extractor you will see that you have vcard attached.
    I would say your admin needs to take a look at that.

    Check out this information on your Exchange server. Especially the part Configuring the Internet Mail Connector (IMC)

    I had that same problem from straight Outlook when I used HTML as my e-mail type. When I switched to Rich-Text it stopped.

    Could be a hint for your administrator.

    I will be contacting them today. I hope there is an answer. Files getting sent like that always seem unprofessional to me. Thanks for the info as I will forward that along to them.

    Here is there response....

    You see this attachment because your device, unlike a Windows Mobile device, cannot interpret the winmail.dat file which contains the rich text info.
    We cannot do anything about it, and the article you send does not apply at all to Exchange as we use it.* The only way to prevent receiving this*attachment is to have email sent to you only in plain text, which we do not recommend you do as not all email clients are as limited as the BBerry one.


    The link I sent was the one from above. Sounds a little bit like a cop out to me... is this a common issue with hosted exchange services?

    sounds like the admin person does not care to help you. Not sure why they would tell you to not do plain text, that doesn't make sense to me.

    I felt the same way on both accounts. I think they are figuring I get a lot of html emails, which I do I guess for work, but there has to be another way to fix this doesn't there? And why is plain text so bad?

    Plain text isn't bad. Only the actual text is sent, none of the funky formatting or cute backgrounds some people use. With plain text any email reader can read it.

    The winmail.dat attachment is a common problem. I don't have any specific information pertaining to the Blackberry but, it is most certainly a problem with specific mail clients. If you were on a Windows system you could simply download a program to decode the winmail.dat and read the message. I am not aware of any such program for the BB. If you want to know more about it then goto Google and type Winmail.dat. You will find all kinds of info.

    See the following URL for a brief and non technical explanation:

    http://www.gpc.edu/~jbenson/resource/winmail.htm

    I can't see why plain text would be bad. In fact HTML is more of a security risk than plain text. Although with plain text you will not be able to see pretty inline pictures, links and other formatting.

    The first step to curing your (Blackberry) addiction is admitting your addicted. What addiction, I don't have an addiction!!!
