Frequently Asked Questions (FAQ)
Where do I print my Marriott Explore Rate Authorization Form?
Log into Marriott Global Source (MGS) at mgs.marriott.com, search for “Explore Rate”, fill in the associate travel details, and print the official signed PDF authorization form. You must present this form and photo ID upon check-in at participating hotels.
Can Marriott hotel guests or Bonvoy members log in through OWA?
No. Outlook Web Access (owa.marriott.com) is strictly for Marriott employees and contractor staff. Hotel guests and loyalty members must manage reservations and reward points at marriott.com or via the Marriott Bonvoy app.
Why am I getting an “Access Denied” error on OWA?
Remote access to OWA webmail may be restricted for hourly non-exempt associates outside scheduled shift hours in compliance with company labor policies. Salaried and exempt employees require two-factor authentication (MFA) to access the system from outside hotel property networks.
