I'm using an 8700G connected to my company's BES server for work email and T-Mobile's BIS service for personal email.

I wanted to send a contact's details to a colleague so created an email and used 'Attach Address' to attach said contact. However, when I try to send it through my work account and the BES server it fails with the message 'Message included an unknown attachment'. Sending the same email using my personal BIS service works, even if the recipient's BlackBerry is connected to the same BES server as mine.

So, it's obviously possible to receive addresses on a BES connected BlackBerry but what do I need to do to be able to send them through a BES server account?

Any suggestions on how to make this work?

You should speak with your BES administrator to find out if he/she has implemented a policy that would restrict these attachments.

Already done that and even had a look at the BES server myself (we're only a small outfit with a total of 5 BlackBerry 8700's connected to the server) and although we can find what file extensions and hence attachments are supported we can't figure out how to add to the list.

Hmm, what are you using for a mail server? Maybe your mail server is rejecting the attachment as invalid? You could test this by taking the email from BIS and forward it to your corporate email account. If that message makes it through (with the attachment) I'm not sure what to make of this issue.

Just sounds like a problem with the BES Service Books on your device. Did you at any time try to do a new Enterprise Activation like you did the first time when getting it set up on the BES? Are you conifugered thru the BES to wirelessly sychronize? You might even try to regenerate encryption keys.

To try this step, go to Options/Security Options/General Settings, scroll just under the word SERVICES, click the track wheel and see if the option "Regenerate Encryption Keys" appears. If so, try that option and then try again.

If that still did not work, I would recommend wiping the handheld, being taken off and then put back on the bes server with a new activation password and then doing a new Enterprise Activation.

Not sure if this would have anything to do with it, but checking your "Security" settings on the bb may be something to look at too. Like check for "Firewall" settings or some of the other security options. Just something else to think about

Also look at your corp email server settings to see if it's allowing for attachments to go thru the bes server. Have someone try to send YOU an attachement from their MS Outlook account. Assuming you have a MS Exchange server, the email should go from the person's computer, to the MS Exchange server, thru the BES Server via port 3101 (only the BES Server can open this portal), thru the Internet, to the Wireless Network of your carrier and to your Blackberry. If this part doesn't work then there may be a setting on the BES Server that's not allowing attachments to go thru that port.

Check with your carrier's Blackberry Help Desk Support Line for further assistance if any of the steps mentioned above still does not solve the problem.

Hope this steers you in the right direction.

We're using BES 4.0 and Exchange 2000.

I haven't tried a new enterprise activation but I have resent the service books. It didn't make any difference.

I've now checked the other 4 devices and they are also unable to send an attached address through the BES server as well.

I don't appear to have that option.

I've checked for the obvious and can't see anything (not obvious to me anyway). The firewall is enabled and can't be disabled for testing.

I'm having no problems whatsoever with other attachments, going in or out.

It has helped me rule out further possible causes but I think I'm going to stop short of wiping the handheld and reactivating it. Because none of the handsets are able to send an attached address I'm pretty sure that it's a BES thing and was hoping it was going to be a 'tick in the box' solution. The fact that it also appears that the file format used for the address only works on a BlackBerry limits it's usefulness anyway ie. it's pointless sending it to anyone without a BlackBerry and if they have got a BlackBerry I can, I've found out, PIN it to them.

It's something that I feel should work and I don't normally like giving up on things like this but for the amount of times I'm likely to use the feature plus the workable alternative using PIN I'm not going to worry too much more about it (unless someone can find the box that needs a tick in it ).

Thanks for your help.
