Sorry David was in a rush, didn't give all the specs. Running EV 5.0 sp4, SP5 will be applied in the next couple of weeks.
I'l give a bit more detail about the background. We are in the the process of an exchange 2000 to e2k3 migration. I have upgraded the FE servers to exchange 2k3 some backends are 2k3 and some are still 2000. When I access a mailbox on E2k3 the Icons do not appear, when I access a mailbox on E2k the icons are present.
Since Upgrading to E2k3 on the FE I have ran the OWA configuration for 2003 as well. Also, when I access the mailboxes directly from the BE of E2k3 the icons do not appear, and I have ran the OWA Configuration on the BE e2k3 servers as well.
thanks for the prompt reply.
