I have a CAS Array configured and noticed that even just getting to the owa website now(by going to https://casarray.company.com/owa) takes a long time

then logging in as the user after i type the un/pw takes quite a while also.

any ideas?

i also tried going directly to the mailbox server which has the cas role installed on it also and it also took a long time.

Hi

Have you got any update on this issue?

How is the environment sized?

Have you tried to run ExBPA and check for issues/warnings?

So, I assume you are using HLB in front of the exchange servers, is it a pure exchange 2010 organization

Since the issue still appears when attempting to access OWA on the CAS server directly, I think the cause won"t be on the HLB

Quote: “i also tried going directly to the mailbox server which has the cas role installed on it also and it also took a long time”

Do you mean that you have tried to access OWA by using the Internet Explorer on the CAS server directly?

Please confirm if the OWA access always slow for all users, including the newly created mailbox and the existing mailboxes

Please check the IIS log on the CAS server, and then check the related traces for troubleshooting

Please also enable the diagnostic logging of the OWA component on the CAS server, which will tell more in the event log

Please also run ExBPA against the CAS server for health check as Jonas suggested
