Outlook UCSF: How to Sign In to UCSF Email on Web, Desktop and Phone

If you searched “outlook ucsf”, you most likely want to get into your UCSF email. Everyone with an active UCSF email address can use Outlook and the other Microsoft 365 web apps through UCSF’s official portal at office.ucsf.edu, signing in with MyAccess and approving a Duo prompt. Desktop and mobile Outlook work too, but they need a premium license, and the desktop client needs the UCSF VPN.

The rest of this guide covers each way in, what you need for it, and where to get help. Everything here comes from UCSF IT and UCSF-affiliated help pages as of October 2026. UCSF changes addresses and policies from time to time, so treat the official UCSF IT site as the final word.

A quick warning about lookalike pages

Search results for “ucsf outlook login” include pages on unrelated domains, such as ticketing sites for sports venues, that walk you through a “UCSF login” with their own links. They are not UCSF pages. Only enter your UCSF credentials on pages reached from ucsf.edu, and only approve Duo prompts that you started yourself. UCSF IT will not ask you for your password by email or chat.

The three ways to use Outlook at UCSF

These requirements come from UCSF IT’s Microsoft 365 and Outlook service pages.

How to sign in to Outlook on the web

Outlook on the web is the option that works for everyone, from any computer, without installing anything.

1. Open a browser. UCSF IT recommends Google Chrome or Microsoft Edge for the best experience.
2. Go to office.ucsf.edu, the Microsoft 365 web portal UCSF IT points to.
3. When prompted, sign in through UCSF MyAccess with your UCSF credentials.
4. Approve the Duo multi-factor prompt. UCSF lists Outlook Web Access among the services that require Duo.
5. Open Outlook from the app list (the “waffle” app launcher in the top-left corner shows all Microsoft 365 apps).

About the different web addresses

You may see several addresses mentioned for UCSF webmail. A UCSF IT Duo page refers to email.ucsf.edu, and an older UCSF IT status notice uses mail.ucsf.edu. The current Microsoft 365 service page uses office.ucsf.edu. Our sources do not say which older addresses still redirect, so if one does not work, start from office.ucsf.edu or the UCSF IT site rather than a link from a search result.

UCSF Health community hospital staff

Staff at UCSF Health Saint Francis and St. Mary’s moved to UCSF systems under Project Ethos, and they had their own instructions. The Project Ethos Outlook quick start guide (2024) describes entering your UCSF email address, signing in with your UCSF username and password, and confirming with Duo Mobile. UCSF Health training material from that rollout also notes that account activation links expire after seven days, so activate promptly if you received one. If you work at one of those sites, follow your local IT instructions first.

Using the Outlook desktop app

The desktop app is the most capable option, but UCSF puts two conditions on it.

You need a premium license. UCSF IT says the web apps are open to all active email users, but the desktop and mobile apps require a premium license. You can request one through UCSF IT. The Microsoft 365 page points to a UCSF IT Help ticket under Accounts, Access & Email, while the Outlook page mentions an Office 365 License Request form. Use whichever the current UCSF IT site offers.

You need the VPN. UCSF IT states that you must be on VPN to use the Outlook desktop client. The student device setup page repeats this for desktop email clients when you are off campus. If desktop Outlook stops syncing at home, check the VPN before anything else.

Installing Office on your own computer

A 2020 UCSF IT notice on changes to UCSF email gave these steps for personal devices, which still match how Microsoft 365 works:

1. Sign in to Outlook on the web.
2. Click the app launcher (waffle icon) in the upper-left corner.
3. Follow the links to install Microsoft 365 apps.

That notice also explained that UCSF switched email to modern authentication, which expired old saved sign-ins. It added that Linux users have no desktop client option and should use Outlook on the web.

Setting up Outlook on your phone

According to the UCSF Library help article on mobile email:

1. Install and set up the Duo Mobile app on your device first. UCSF says this is required before Outlook Mobile.
2. If your phone still has an old UCSF account set up through the built-in mail app (ActiveSync), remove that account first.
3. Follow UCSF IT’s Outlook Mobile instructions. They are published by UCSF IT and you need a MyAccess login to view them.

Because UCSF lists the mobile apps as premium-license features, confirm your license status before you start.

Opening a shared mailbox in Outlook on the web

Many UCSF departments use shared mailboxes. The Project Ethos shared mailbox guide describes the web steps:

1. In Outlook on the web, select your profile picture or initials in the top-right corner.
2. Select Open another mailbox.
3. Type the shared mailbox’s email address and select Open.

You can only open mailboxes you have been given access to, and sending from one needs separate send permissions. Ask the mailbox owner or UCSF IT if a mailbox is missing.

Duo and sign-in problems

Duo is the step that trips most people up. UCSF IT’s Duo FAQ and Duo service page are the official references. A few practical points from our sources:

• Duo Mobile is the recommended method. UCSF Health training from 2024 notes that UCSF IT can provide hardware tokens for people without a phone or tablet.
• New phone? You need to re-establish Duo on the new device before Outlook Mobile will work. Contact UCSF IT if you no longer have the old device.
• Repeated sign-in prompts in desktop Outlook usually point to the VPN being off or an old saved sign-in. Signing out and back in, with the VPN connected, is a reasonable first step before calling for help.

Where to get help

UCSF IT says to submit a ticket through the Employee Self-Service Portal (ucsf.service-now.com/ess). The IT Service Desk can also be reached at ITServiceDesk@ucsf.edu. Older UCSF notices list the phone number 415-514-4100, but that comes from 2020, so check the UCSF IT site for current contact details.

When you open a ticket, say which version of Outlook you are using (web, desktop or mobile), whether you were on VPN, and what error you saw. Never include your password.
