| | Users on new Exchange server cannot send
Please Login to Remove!
We have a BES 4.0 setup and all has been working fine for the past 12 months or so.
We have a single MS Exchange 2000 server called "mail2" and it has been happily sending messages out via our BES server for over a year.
All our users have also been able to send from their Blackberry devices etc.
We are now in the process of installing a new MS Exchange server.
Because I've got a lot of users this is a bit of a slow process.
We've bought the new Exchange 2003 server online (called Lysine) and we are slowly moving users across from one server to the other.
The BES account has been moved onto the new server.
Everyone is still getting a feed to their Blackberry device - so if the user is on mail2 (old Exchange 2000 server) or Lysine (new Exchange 2003 server) they still receive any e-mail they are sent.
However, any user who is attached to the new Exchange 2003 server cannot send from their Blackberry device.
They compose the new message, hit send and almost immediately it appears in their inbox with a red cross next to it and the message status:
Unlisted message error
If I remember correctly, when the BES server was first installed the name of the Exchange server was specified.
So maybe something needs changing here?
However I need the ability for users of both Exchange servers (for the time being) to be able to send & receive messages to their BB device.
