Outlook at University of Arizona: How to Sign In to UArizona Email

To use Outlook at the University of Arizona, go to outlook.arizona.edu and sign in with your @arizona.edu address (your NetID plus @arizona.edu), your NetID password and a NetID+ (Duo) two-factor check. This now covers students, faculty, staff, and also alumni and retirees, because the university moved its remaining Gmail-based “CatMail” accounts to Microsoft 365 Outlook in 2025.

A lot of older pages, bookmarks and orientation handouts still mention CatMail or catmail.arizona.edu. That’s why many people search for “outlook university of arizona”: the old route no longer works the way it used to. Below is what changed, how to sign in, and what to do when it doesn’t work. Details are current as of November 2026 and are based on University of Arizona IT pages, university announcements and student press coverage; the university can change them, so check Arizona IT if something looks different.

What changed: CatMail to Outlook

For years, University of Arizona students used a Google-based account called CatMail. The university then consolidated email for everyone on Microsoft 365.

Students

According to the university’s announcement, student email and calendars moved from Gmail to Outlook in Microsoft 365 on Friday, July 25, 2025. Students kept their existing @arizona.edu addresses, and existing Gmail messages and calendar events were migrated to Outlook automatically.

The Arizona Daily Wildcat reported in September 2025 that student Gmail stayed read-only until October 1 before being retired. University IT’s CatMail Has Moved page says the old CatMail addresses for students now generate an automatic reply, so anything still pointing there should be updated.

Alumni and retirees

Alumni and retirees were on a separate schedule. University IT’s alumni and retiree page says their Gmail and Google Calendar were migrated to Outlook on Tuesday, November 4, 2025. Their @arizona.edu address stayed the same, and their Google apps were deleted afterward, with Google access ending later that November. The same page says retirees gained access to the Office online apps, and the @email.arizona.edu address still delivers to the same mailbox.

The Arizona Alumni Association also says alumni sign in at outlook.arizona.edu with their NetID password and two-factor authentication.

How to sign in to UArizona Outlook on the web

You need three things: your NetID, your NetID password, and a working NetID+ two-factor method (usually the Duo Mobile app).

1. Open a browser and go to outlook.arizona.edu. Type it yourself rather than clicking a link in an email.
2. When the Microsoft sign-in page asks for your email, enter your full address in the form yournetid@arizona.edu.
3. You’ll be sent to the University of Arizona’s NetID login. Enter your NetID password there.
4. Approve the NetID+ (Duo) prompt on your phone, or use another method you’ve set up.
5. Your Outlook mailbox and calendar open in the browser.

If you’re brand new, the university says an Outlook account is created automatically when you set up your NetID and password, so there’s no separate email signup. Some older university pages note that a new account can take a day or two to become active. If you’ve just created your NetID and can’t get in yet, wait a little before contacting support.

A note on NetID+ and Duo

NetID+ is the university’s two-factor layer, and it runs on Duo Security. It’s required for active members of the university community. University guidance for new students says to install the Duo Mobile app first, set it up, and then enroll in NetID+.

University IT also says you should never approve a Duo prompt you didn’t start. A surprise prompt can mean someone else has your password. Deny it, then change your password at netid.arizona.edu.

Using the Outlook apps on your phone or computer

Because the account is a standard Microsoft 365 mailbox, it works with Microsoft’s own Outlook apps as well as the web version. The general pattern:

1. Install Outlook from your device’s official app store, or use the Outlook desktop app if you already have it.
2. Add an account using your netid@arizona.edu address.
3. When redirected, sign in with your NetID password and complete the NetID+ check.

I couldn’t find step-by-step mobile setup instructions in the public pages I reviewed. University IT does publish Outlook mobile setup how-tos (linked from its “Is your phone ready for school?” news item), so follow those if your device asks for server settings or behaves differently.

One practical tip: if you used a phone’s built-in mail app to read CatMail through Gmail, that connection points to Google and won’t receive new mail after the move. Remove the old account and add the Outlook one instead.

Troubleshooting common sign-in problems

“I keep ending up at Gmail or a CatMail page.” Your bookmark or saved account is out of date. Bookmark outlook.arizona.edu instead, and remove old Google-linked mail accounts from your devices.

“My password doesn’t work.” Reset it through the official NetID site at netid.arizona.edu. University IT also points people there if they think a password was compromised.

“I’m not getting the Duo prompt” or “I got a new phone.” Two-factor problems are where the 24/7 Support Center comes in. University guidance says that if you don’t have the mobile app available, you’ll need to call the Support Center to help you sign in.

“Something says I need the VPN.” You don’t need the VPN to read email at outlook.arizona.edu. University IT says the UA VPN is for reaching certain secured campus systems from off campus. That’s a separate thing from Outlook.

“Messages from before the move are missing.” The university says existing Gmail messages and calendar events were migrated automatically. If something important seems to be missing, contact support rather than trying third-party migration tools.

Where to get help

• Students: the university’s 24/7 Support Center, linked from IT for Students.
• Faculty and staff: Arizona IT, via the IT faculty/staff resources pages.
• Alumni: the Arizona Alumni Association’s email page and the alumni and retiree IT page.
• Passwords: netid.arizona.edu.

As a general rule, never send your NetID password by email or chat. Treat any message asking for it as suspicious, even one that looks like it comes from “UA IT” or “Microsoft,” and check with support through the official IT site.

The short version

Bookmark outlook.arizona.edu, sign in with netid@arizona.edu, your NetID password and NetID+, and forget about CatMail. Students moved on July 25, 2025, and alumni and retirees on November 4, 2025. Faculty and staff were already on Outlook. Anything still pointing to the old Google account, whether a bookmark, phone mail app or forwarding rule, is the most likely reason you’re stuck.
