Outlook 2010 and OWA slow to access Exchange 2010, Server 2008
I have recently installed the above environment upgrading from Server/Exchange 2003. The mailboxes connect to the Exchange no problem when setting up Outlook but keep timing out during the day - that message pops up 'Trying to connect to Exchange Server' in the bottom right corner. OWA is also slow and it's nothing to do with ADSL speed - it just says WAITING. The TS machine's Outlook also crashes too often when using Outlook. There's 16GB RAM in ther on a Proliant ML370 G6 and is otherwise a speedy machine. Just seems to be slow authentication issues with the Exchange. The Exch MGNT tool still sees the 2003 server although that machine has gone and all roles seem to have transferred fully. Could the PC's still be looking for the OLD 2003 Exchange? Thanks in advance.
