Michel and others, I'm sort of confused... I've been mucking around with IMAPAdapter for a while now (against an Exchange 5.5 server), and I can't seem to even get it to run the simple test code distributed in readme.txt. Here's what I've done: created a folder off the root called imaptest created user defined roles in the root folder for IMAPUser and NotMail, giving them all permissions to that folder in the security tab. Within the imaptest folder I gave all permissions to the same roles for that folder. I then added the imapadapter and the index_html (with the sample code) into imaptest . Instead of it working, it denies all access to the directory, whichever username I use. I know IMAP is working because I tried it against a client (Outlook Express) from the same box. THere are no users defined at the root ( in acl_users ). Any help?
