What this is for
Outlook Web Access (OWA) is Marriott’s employee webmail system. It’s for current Marriott associates, not guests or customers.
Logging in
Go to owa.marriott.com and sign in with your domain/username and password — the same link works for all employees.
Marriott Global Source (MGS)
Broader HR and work tools are on Marriott Global Source at mgs.marriott.com, signed in with your Enterprise ID (EID) and password, or a security key.
Forgot your login?
On mgs.marriott.com, choose “Forgot your EID or password” and follow the recovery prompts. For OWA-specific issues, contact your property’s IT team or the Marriott helpline.
Job applications
Marriott job postings and applications are handled separately at greatjobs.marriott.com — that’s a public careers site, not the employee OWA/MGS system.
Getting help
For account-specific issues, use your property’s IT team or the contact information on mgs.marriott.com rather than a number found elsewhere.
