I'm finding it somewhat difficult to find specific information flows for PIN/Peer to Peer messaging on BlackBerry's support site.
Here is some generic information from the discoverblackberry site, however.
PIN Messaging |
Sending private emails only between BlackBerry devices. A BlackBerry PIN is a special address code similar to a postal code or phone number for sending emails only to other BlackBerry device users. This is not compatible with phone numbers, email addresses or SMS (text messaging). It is an entirely different kind of an address. Not every BlackBerry user needs to use PIN messaging, but the feature is considered a valuable feature, especially for security purposes.
P2P* (Pin-to-Pin or Peer-to-Peer)
The BlackBerry service allows messages to be sent directly between handhelds using PINs. It provides backup when email is down and private mail routing around a BlackBerry Enterprise Server. This feature can be disabled by companies for security purposes.
*P2P messages are not forwarded to the userxxx8217;s desktop mailbox and are not encrypted.
The only way the sysadmin could affect PIN messaging is if he has disabled it completely via the BES policies (with exception to the peer-to-peer encryption policy which I don't know too much about its implications, but this sounds very possible as to the cause of the problem), and that would remove the option to PIN, not limit it...can you tell us her process exactly?
Something else to try is to install BlackBerry Messenger, since this is just a different way to PIN message another user (friendlier).
Let us know how it goes...
