    Attachments arrive as ATT0000?.DAT (2000 SP-3)

    There must be something obvious that I'm missing!
    When I send an attachment (Word.doc; Excel.xls or whatever) it always arrives as ATT000?.DAT - if I rename the file it is still in the original format, but those who receive the attachments think that it is corrupt.
    Attachments arrive OK
    I have tried changing my mail format (plain text, HTML, RTF) but makes no difference to the attachment.
    Appreciate any suggestions!

    Does the information in OL2000: How Message Formats Affect Internet Mail help?

    Thanks Hans,

    I agree that it ought to help - but it doesn't work for me!
    I've turned off TNEF but the problem persists

    Best wishes - daktari

    <P ID="edit" class=small>(Edited by jscher2000 on 18-Jul-03 14:49. Should have read MSKB before posting.)</P>Try entering the recipient's address manually. Sometimes "use RTF" or "don't use plain text" is stored in their contact/address book record, and this will override your choice during composition.

    Oops: I see that was covered in the MSKB article. Might still be worth a try because allowing Outlook to auto-complete the address denies you control over the setting.

    The MSKB article is pretty long, make sure you read the section near the end titled "Per Recipient Change".

    Re: Attachments arrive as ATT0000?.DAT (2000 SP-3)

    Thanks for the suggestions .... but I've done this & sent test emails with Word attachment to myself (from my work email address to home address) - & manually switched off TNEF + sent as plain text.
    It still arrives with the attachment "converted" to a name such as ATT00006.DAT !

    Re: Attachments arrive as ATT0000?.DAT (2000 SP-3)

    Does it have something to do with the encoding of the attachment? UUencode vs Base64 and whatnot? I think in Express you have a little more control over the outgoing attachment encoding. i searched for help in Outlook (2002) "attachment encoding" and got this:

    Use UUENCODE format to send messages and attachments
    On the Tools menu, click Options, and then click the Mail Format tab.
    Under Message Format, click Internet Formatting.
    Select the Encode attachments in UUENCODE format when sending a plain text message check box.

    its a bit confusing to find, but maybe it'll help?

    Dear Mark,

    I thought you might have been onto something ... but even after switching to UUENCODE format my attachments, whether Word docs, Excel spreadsheets or whatever still arrrive as ATT.......DAT .
    Thanks for the suggestion!

    Does the attachment arrive as an ATT...DAT to EVERY recipient? (i.e. does it matter what email client they use?)

    If so, could you send a sample attachment to me at leif@wopr.com?

    Hi Ian, I googled (man, what a geek I am, Google has become a verb in my vocabulary) [img]/forums/images/smilies/biggrin.gif[/img] for att .dat

    I found this site and a little "converter site" I don't have any att.dat attachments in my inbox right now to try it on, so I haven't tested it, but you can give it a whirl, maybe it'll do the trick

    http://www.steveion.ic24.net/stuff/nettel_header.htm

    oither hits alluded to PGP signatures and Outlook's "non-compliance with the standard" and other linux rants about ms products and stuff . I tend to start skimming when someone's bashing for the sake of bashing or self-gratification [img]/forums/images/smilies/smile.gif[/img]

    Are you on an Exchange server? If not, nevermind. If so, does this happen when you send to other users on your site or only to users across the internet?

    If the problem is only with messages that go out across the internet, then it may be that the Exchange Internet Connector has been set to ALWAYS send as RTF, which would override anything you might try on your end. This option is generally set to USER, which defaults to RTF but lets you modify it for contacts in your address book.

    OK - received here using Outlook 2002 and no problems at all with either the Word or Excel attachments!
    I can't immediately see anthing untoward with the header.
    (Your X-Mailer: header is "Internet Mail Service (5.5.2653.19)" where I would expect to see "Microsoft Outlook.....")

    Is it possible it may be related to the size of the attachment?
    Would your attachments normally have anything embedded in them (e.g. logos) ?
    Do other users on your network suffer the same with their outgoing mail?

    Given the X-Mailer header, it could be that OldDog's comment about Exchange Mail Server settings is on point.

    Yes, I am sending through Exchange Server - & it's only off-site emails that are affected. I shall certainly check this out.
    Thanks
