I have just migrated from GW 6.5 on Netware to GW 7.0.2 on Linux. All is good but the Blackberry Enterprise Server collaboration service. When trying to connect to Messenger from a Blackberry I get an "Unknown error: d15e" on the Blackberry. Messenger logs, however, show the following:

BB0 SPL Login failed [0xD15E]: - The server is too old.

I have not a clue what that means nor how to resolve it. Any ideas would be welcome.
