SYMPTOMS
When you use Microsoft Internet Explorer 4.0 or Netscape Navigator 4.x to gain access to Microsoft Outlook Web Access (OWA) and you open two different mailboxes (that reside on the same server) with two browser windows on the same workstation, if you perform any action on the mailbox for which you did not enter credentials most recently, you are prompted again for credentials (this assumes that users do not have rights to each other's mailboxes).

For example:  User A logs on to the UserA mailbox by using the following Uniform Resource Locator (URL):

http://servername/exchange/userA

When prompted, User A types User A's user name and password. User A opens a second browser window and logs on to the UserB mailbox by using the following URL:

http://servername/exchange/userB

When prompted, User A types User B's user name and password. When User A attempts to perform any operation to the UserA mailbox in the UserA mailbox browser window (for example, view the Calendar, open a message, or create a message), User A is prompted again for User A credentials. After User A re-types the User A credentials in the UserA mailbox browser window, when User A attempts to perform any operation to the UserB mailbox, User A is prompted again for User B credentials.



CAUSE
This issue occurs because the browser maintains one set of credentials for each server, for each session of the browser.



WORKAROUND
To work around this issue, log on to the domain by using an account that has the appropriate permissions to log on to both mailboxes.
