In the last couple of days I have deployed two BlackBerry Enterprise Servers for customers and in one case where I was reinstalling the existing BES I saw what is a very common issue.
On the handheld the error message reads:
transaction error-decryption error, and in the server event logs you may see {user_name} DecryptDecompress() failed, Tag=24207815, Error=609
This message will occur when the user’s encryption key has expired and needs to be regenerated. To regenerate a key from the device do the following:
- Go to Options (Settings then Options on some devices)
- Select Security Options
- Select General Settings
- Scroll down to Services and highlight “Desktop [SXXXXXXXX] (***)”
- Press the trackwheel or Menu Button and select “Regenerate Encryption Key”
Once you have performed these steps it should resolve the “DecryptDecompress() failed” error. Once that issue is resolve ensure that “Connection and Collaboration Services” is enabled for this user.
