Wav files not showing up in OWA

We have a phone system that emails us with wav files for voicemails.

For some reason they do not show up in OWA when you open the message.  We are running Exchange 2003.  

I found an article that shows registry keys where you can set restrictive file types, but wav is not listed in these keys.

Any help would be greatly appreciated.

The value was there, and it was not working.  

I have now tried to remove it, which should force it to download.  This also is not working.

The attachment simply does not even show up there.

Try setting the Antivirus exclusions for the database

Where would I find these settings?
0
NpatangCommented:
In the antivirus itself.  Also try this ..
try creating the rule in the Outlook itself that whenever the mails comes from the phone systems it forward the mail again to the same user .. See if then you can view the attachment in the OWA

Symantec mail security is being used for these messages.  The attachements show up in normal email, so there is no separate setting for OWA.

If I forward the message, it does show up.

NpatangCommented:
I think Anitivirus is blocking it somewhere , becuse if it does show up when you forward it shows in OWA so there is no registry settings which causing the issue.

See in the Antivirus if you have option to Excude the database files so that it doesn't scan it.

Try forwarding the same mail to yourself and check if you can view those in OWA, This issue mainly occurs because of some invalid headers those are not recognized by OWA.
If forwarding resolves the issue then you have to contact the phone systems and get the header information changed so that they can be viewed in OWA as well...
Best Luck !!

Forwarding looked good.  Going to try to get the header changed.  Will let you know.

Do you know if there is anything the must be, or must not be in the header?

NpatangCommented:
Its tough to say that what needs to be modified in the header files, But forwarding did that for you ,,, that sounds good

If you can help with the header information, probably we might be of some help....

Header looks like this.  Names and IPs have been masked.  Please let me know what we can do to get this to work through OWA for these voicemails.

I suspect Baracudda here, can you test this without Baracudda??
0
TacoFlavoredKissesAuthor Commented:
Unfortunately no.  We use barracuda to filter all incoming mail for all domains and there isn't an easy way I can think of to do this without changing the MX record.  
0
SaakarSenior Technical ConsultantCommented:
The reason I am suspecting Baracudda is, if we forward that same message to ourself it works fine, right so in that the message is not scanned by Baracudda and hence the headers do not change, either you have to work with your Voice Messaging S/w vendor to fix the issue, or create a rule in Outlook that forwards any .wav attachments back to you.

You can actually compare the header of a forwarded message with the original message and find out the difference between the two.

Not so far.  I have been pulled away on other things.  I plan to take one of the messages and send it through the cuda again to see if it behaves the same way.  Also looking to open an alternate way in to test the VM email.  I will report back when I have, but likely a few weeks out.
