Hello

I am running Exchange 2007 sp2, i have two VM's that are running CAS/HT and

one physical server that is running the MBX role. The two CAS server are

configured for wnlb, all servers are running 2008 sp2. The outlook clients

connect to the Exchange servers over a MPLS connection, to the datacenter,

and all outlook clients are running Office 2007 sp2. What i have been

noticing lately is Outlook will at times during the day present a logon

prompt to the user, asking the user for credentials, this happens roughly 3

times a day, and when the user puts in the credentials the user is able to

connect.

What i am trying to determine if this issue is being caused by the network,

or this is somesort of core exchange problem that is causing this? I have

autoconfiguration configured, and it is working, i have no problems

dounloading the oab, viewing free\buys, or turning on OOF, these services

all work fine, externally and internally. Is there any type of Exchange

auditing that i can turn up that might help me determine or rule out if this

is being caused by one of the exchange servers?

Also other than providing OOF, OAB, and availability service, to outlook

clients, does the CAS server also connect the outlook clients to the mailbox

server role? in other words is Outlook talking to the CAS server, and the

CAS server tells outlook what mailbox server that users mailbox is on? If

the CAS server was turned off would internal outlook 2007 clients still be

able to make a connection to the mailbox server?

Many thanks for any advice

Do your users have admin rights on your network?

I have found that sometimes users who use owa

to connect to outlook choose the option to have IE

remember their username And pw. If this happens, you will need

to have the users log into the machine having the

issue as and admin, go into control panel, go to user accounts

go to the advanced tab and select manage passwords.

Remove the password from this tab, if found, and give it another go.

I'm not sure if your issue is that simple but this happened

to me a while back and drove me bonkers. Good luck!
