Nothing to do with TS or Citrix at all. There is a good chance that I'll have to make an app soon to make a POP3 connection to our exchange 5.5 server. My current stumbling block is how to enter the required username and password. In my tests so far, the usual "domain\username", "username" and "mailbox.alias" attempts all fail with "A required privilege is not held by the client". So, does anyone happen to know the format for the login details when connecting to POP3 on MS Exchange 5.5? *********************************************** For Archives, to Unsubscribe, Subscribe or set Digest or Vacation mode use the below link. http://thethin.net/citrixlist.cfm
