  • unable to open certian attachments in OWA

    I am running Exchange 2003 and Exchange 2007 in co-existence environment and in the midst of moving Mailboxes. Users whose mailboxes are on exchange 2003 are unable to open certain attachments e.g. *.java etc. through OWA . Uses get the following error when they right-click on attachment and chose Save Target As…
    “Unable to download xxx.java from website.com.
    Unable to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.”
    There is no issue opening these attachments through regular outlook for both Exchange 2003 and 2007 users.
    Thanks,

    Thats not an Exchange generated error.
    Have you tried to do the same in another browser IE FireFox or Chrome? Alternatively open EMC Server Configuration>Client Access>Outlook Web Access>Properties>Public Computer File Access>Customize and check what extensions are allowed or blocked.

      Thank you for your response. I added the file extension in the allowed list but still having the same issue. Chrome and Firefox give
      "404-File or directory not found. The resources you are looking for might have been removed, had its name changed, or is temporarily unavailable." error.

        Check your AntiVirus client side and server side on the CAS to see if its doing attachment scanning.
