Micro Focus Service Desk Email Configuration can connect to just about any IMAP & SMTP service.

MFSD can be configured to connect to gmail imap/smtp services.
However, if you haven't gotten a certificate from Google you will have a settings on Google side to allow access using their gmail services for MFSD.
Using IMAPS and TSL(SSL) is still secure and going over port 993 and 587 (defaults), but the security setting on Google side must be configured also as non-secure to allow those services in.
