I have just setup WAB on Exchange Server 5.5 and in testing I find that all that is needed to get to the E-Mail is the mail user ID, no password required. Now these tests are being done on the existing network, but I think a password would be in order. WAB als o only works for the user currently signed on to the system attempting access and will not allow access to another user. Is there a way to protect with a password and also allow access to another user from a system signed on to some other user (e.g. sys admin working at another station).? I have ordered the latest service pack (about a month ago) as my system appears to be without any service pack at all (5.5 Build 1960.5).
