    iphone 4 forwarded .docx or .pdf files.  In Outlook, they appear as .dat and .htm files AND the files are renamed as ATT*    If I reduce the filenames to less than 65 characters, then they are all ok.  Is there a config on the exchange server to increase this limit?  Am using exchange 2003.  I've also tested this on an exchange 2010 server, and it doesn't have this issue.

    Forwarding from Outlook does not cause the same result.  Forwarding from an Android device or Blackberry device does not cause the same result either.

    Hi,

    This sounds like it's probably a limitation on filename size or the file name is getting wrapped. Try saving and changing their extensions back to .docs and .pdf in Outlook and see if they open.

    Yes, The .dat files after being renamed, are the .docx, .pdf, or even .pptx files.  The receiver doesn't know what they are or what their original file names are. 

    Is there some config that can be modified on the exchange 2003 server which will allow attachments with filenames longer than 65 characters to pass through as is?  I've tested with an exchange 2010 server and the attachments come thru fine.  No filename or file type conversion occuring.

    Hi Justin,

    Based on my experience and research, on the Exchange server side, we do not have this kind of limitation. This looks like an iOS's problem Exchange 2003 could not but Exchange 2010 could handle . Maybe you could try to contact Apple and see if they could offer any help.

    The content conversion of Exchange 2003 and 2010 have many differences. On the Exchange side, our suggestion is: 

    If you have both Exchange 2003 and 2010 servers in your organization, we suggest you to move the users who have this kind of demand to the Exchange 2010 server, or suggest your Exchange 2003 users to use shorter names.

    Thanks,

    Andy

    Am going to try to make a few minor changes to the Internet Message Format on 2003 Exchange server and see if it helps.  Will know at the end of the week.  Thanks!

    Tried a couple changes in Internet Message Formats but nothing made a difference.  We are moving on............  Will be moving to Exchang 2010 shortly.

    Thanks. Unfortunately I don't have that luxury right now, but I'll just reiterate what I told him to do once I found out about this issue. Just save it locally then rename the file to something much shorter. That or send it outside of the iOS.
