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,
