So frustrated!!! Still chasing down my problems with BB Messenger. The scenario continues...

I can exchange messages with people outside of my network (company uses a BES). Originally, I thought nobody inside my company's BES could use Messenger with each other, but it's JUST ME!!! Others are communicating with each other just fine!

I've tried comparing settings on the handheld with others. Seems like all the settings match, but still no dice. In fact, not really sure which setting might have made this happen, but now I can accept or send an invitation to someone, start a conversation, and send the first message. I get the check mark next to the message, and the little 'D' next to the check mark. Then, I get the decryption error again. I've even just done a Network Activation with the BES, just to make sure there wasn't any communication errors between the BES and my BB.

Anyone else got any ideas? I'm so frustrated, and even more so, now that my colleagues can speak with each other, but just not me! Aargh!!!

Thanks for your suggestions.

1. download blackberry desktop manager 4.0.1 sp1 and install
2. delete both desktop service book entries on your blackberry
3. re-sync your blackberry and generate a new encryption key
4. remove blackberry and send yourself an e-mail from outlook
5. reply to the e-mail from your blackberry
6.verify you receive the e-mail
7. enjoy your day!

Not having any trouble with e-mails. E-mails work fine. It's only receiving PIN messages that are causing me problems. Already on 4.0.1 SP1. Can you tell me more about what will happen if I dleete the desktop service book entries? Will those be re-created automatically? Will I lose any data? Will all my apps continue to work ok?

Thanks for the suggestion!

They will be recreated when you sync, you "might" have to reload your apps, but not sure.

"2. delete both desktop service book entries on your blackberry"

Trying to use Desktop but with emails being redirected on BES I have still to find a solution that works. In your fix you recommend deleting the two Desktop service books. I have six:

Desktop [BrowserConfig]
Desktop [SYNC]
Desktop [CICAL]
Desktop [IPPP]
Desktop [ALP]
Desktop [CMIME]
Provisioning [PROVISIONING] - dont know what this does??

Any clues which to delete?

Thanks
