Hi all, Need your help regarding : we have 2 CAS server. Exchange 2007 SP1 Rollup 6. I find out that 1 of the server is have Auth : Plain authentication. Can I remove the authentication? Tried some method but cannot works : set-imapSettings -server servername -LoginType PlainTextLogin But it's still not remove the Auth : Plain The weird things is the another server is without Auth : Plain. Below is the result from telnet command : Server 1 (without Plain) + > * OK The Microsoft Exchange IMAP4 service is ready. < A0 CAPABILITY > * CAPABILITY IMAP4 IMAP4rev1 AUTH=NTLM AUTH=GSSAPI STARTTLS IDLE NAMESPACE LITERAL+ > A0 OK CAPABILITY completed. Server 2 (with Plain) + > * OK Microsoft Exchange Server 2007 IMAP4 service ready < A0 CAPABILITY > * CAPABILITY IMAP4 IMAP4rev1 AUTH=NTLM AUTH=GSSAPI AUTH=PLAIN STARTTLS IDLE NAMESPACE LITERAL+ > A0 OK CAPABILITY completed. How can I remove and readd back Auth=Plain (if something happen)? Thanks!!! carckermania

You should be able to do it via Exchange MAnagement Console, select IMAP under Server Configuration | Client AccessWith kind regards Krystian Zieja http://www.projectnenvision.com Follow me on twitter My Blog
