I've started to setup MobilePrint and I run into this error for our IMAP setup:
I checked and IMAP is on.
Is the SSL certificate that is on the IMAP server one that is self issued? i.e. Issued by your establishment rather than a Root Certificate authority? If so you'll need to add the Certificate Issuer as a trusted Root Authority on the server running mobile print.
Ask the issuer for the Root CA cert then
