Note

ActiveSync is not a complete Microsoft Exchange replacement. We recommend IMAP for most clients. ActiveSync can be useful for e.g. Android.

If your email client asks you for IMAP Path Prefix, you can leave this value empty. All relevant folders are located directly in the root directory of the mailbox.
