I have OWA running (Exchange 2003 on Server 2003R2) and everything seems
to be working, but I have one big security hole that I am sure is caused
by an incorrect setting on my part.

 

Once users authenticate into their account, they can access any other
account they wish by changing the URL.

 

Example:

You authenticate to this address for OWA:

https://exch.mydomain.com/

 

You then go into your mailbox at:

https://exch.mydomain.com/exchange

 

if you add anyone elses username to the end of that URL, you can see
their email account, example:

https://exch.mydomain.com/exchange/bsmith

would show you bsmith's account.

 

I am sure this is something very basic I am missing.

 

Thanks,

Ed
