BB 8700G on T-Mo, using BIS.

I get msgs on my internet server saying:

This message is used to carry data between the BlackBerry Handheld and an associated server. Please do not delete, move or respond to this message - it will be processed by the server.

BEGINETP 167 (etc)

My mailbox is filling up with these. Do I have to keep all of them on the server, or can I delete all but the last one?

Also, can I delete all of them on my BB, and that I've downloaded to Outlook? Those wouldn't affect anything, it seems.

Thanks

Something is wrong with your BIS setup. Are you sure you did not activate BES?

Or did you try and use the Desktop Redirector?

I don't think I enabled BES. How would I check? I don't have the service with T-Mo. I did use the desktop redirector for awhile at work, but turned it off over a week ago and still get these msgs. I also get them with my Yahoo POP3 account.

Thanks

delete the deskpt service books from your BlackBerry
uninstall - not turn off - redirector from your computer

shoudl fix your issue
