Another solution that worked for us is to add the username data to the mailbox parameter using the appropriate flags.

For example, with the Office 365 configuration of

USER EMAIL: user@maindomain.com
PASSWORD: password
SHARED MAILBOX: shared@anotherdomain.com

then the imap_open call would be

imap_open("{outlook.office365.com:993/imap/ssl/authuser=user@maindomain.com/user=shared@anotherdomain.com}", "user@maindomain.com", "password");

Note the inclusion of the main user email using the /authuser flag and the shared mailbox using the /user flag.

That worked for us when the mailbox alias approach in the previous answer was not successful.
