You can have your email delivered to a different address

OIT supports 3 email services: UCI Gmail, Microsoft Exchange (aka Office 365) and ES Mail (aka Webmail). Broadly speaking,

  • Since 2014, all new students receive UCI Gmail
  • Staff & Faculty may use any of the above (depending on their department)

Not sure which one you're using? Visit What's My Email?

NOTE: Health Sciences (HS) and UCI Medical Center (UCIMC) users are required to use Microsoft Exchange; however, they use a different Exchange server than the rest of campus (due to HIPAA requirements). For email support, we recommend they contact their HS Help Desk at (714) 456-3333.

ICS grad students & Law School students use their own instances of UCI Gmail. See below for more information.

Email login issues

If you are unable to login to your email account, first make sure you're visiting the correct website.

If you're at the right website but still can't login, it may be time to reset your password. However, if you've already reset the password and are still having trouble signing in:

  • Exchange/Office 365:
    • Remember that you are only entering in your UCInetID (e.g. "ptanteater"), not your full email address.
    • You may need to clear your browser's cache, cookies and *hosted app data" (Chrome) or "offline data* (Firefox) or "website data" (Safari). Then, quit your browser, relaunch it and try logging in again.
      • Learn how to do it here.
  • UCI Gmail:
    • If you're a recent graduate and are seeing a message that your account has been suspended, it's time to renew the account. This must be done annually.
  • ES Mail (aka Webmail):
    • If you're still getting Login Failed when trying to login, please open a ticket. It's possible your mailbox may have been archived and we'll need to investigate.

A note about new students and UCI Gmail:

I just changed my email password. How do I update the password that's stored on my computer/mobile device?

I'm a new student. How do I access my UCI Gmail?

This following applies to incoming freshman, graduate students, transfer students, and Continuing Education students. All new students will be notified by OIT via the email address they used to apply to UCI when their email accounts are ready. Before you can use your UCI Gmail account, you must activate it first.

I'm a new student in the School of Law/graduate student in the School of ICS. How do I check my school's Gmail account?

Both of these schools manage their own instances of Gmail/G Suite for Education, which are separate from the UCI Gmail system:

  • LawNet (email address format is UCInetID@lawnet.uci.edu)
    • Available to all of their students.
  • ICS Gmail (email address format is UCInetID@ics.uci.edu).
    • Available to graduate students only. Undergrads use UCI Gmail.

Why is my UCI Gmail account suspended?

Your Gmail account may be suspended for one of the following reasons:

  • You're working for Health Sciences (either the School of Medicine or the UCIMC).
    • If you work for a department in Health Sciences or the UCIMC, the HS Help Desk requires you to use the HS Exchange email system and they will change your email delivery point to @hs.uci.edu (if you'd like to see where your email delivery point is set, you can visit What's My Email?) As a result of this change, your UCI Gmail account will be suspended due to HIPAA. There are no exceptions to this and the OIT Help Desk cannot change this. At best, we can unsuspend your account for 3 days so you can forward any emails out or download files. Open a ticket to obtain temporary access.
  • You're an alumnus and you didn't renew your account.
    • Alumni are required annually to renew their UCI Gmail accounts; failure to do so will result in account suspension and eventually deletion. OIT will send you multiple reminders to do this, but if you aren't checking your account regularly you'll miss them.
  • Your account was suspended for abuse because Google suspects it was compromised.
    • Google will suspend accounts that are breaking their terms of service, usually because the account's integrity has been compromised. When this happens, follow Google's instructions to reset your UCI Gmail password first. Once you've done that, open a ticket with OIT and we'll unsuspend the account.

Please note that when calling the Help Desk, sometimes the phone agent will not be able to see the reason why you are suspended and will need to open a ticket to escalate the issue.  When this occurs, someone will be in touch by phone or email soon thereafter to explain the reason for the suspension.

I want to change how my name appears in UCI Gmail.

We have detailed instructions on how to change your Display Name in Gmail here. However, if you're trying to change your name globally, unfortunately it's no longer possible through G Suite. We suggest visiting the Student Access section of the Registrar's website and submitting a Name Change request in their system.  Once it's approved, it'll reflect everywhere (including G Suite).

How do I change my email address?

Your email address and UCInetID are linked. So if you would like to change your UCI email address, you will need to submit a request to have your UCInetID changed. You can read more about that process here.

I just changed my UCInetID. Can you forward my email to my new address?

Yes. By default, we will forward your email from your old UCInetID to your new UCInetID for 1 year.

I no longer work for UCI. Can I keep my email?

If you are retiring, yes. There is a form on the Center for Emertii & Retirees website that you must download and fill out. Instructions can be found on the form. Otherwise, separated employees can keep their email for just 90 days from date of separation. At that point the mailbox is deleted. If your are still collaborating with someone at the university past 90 days, please ask a colleague or supervisor in your department to sponsor you for a Guest UCInetID, which will allow you to keep your email for an additional 4 quarters. Unfortunately the OIT Help Desk cannot sponsor you or extend your access at your request.

Can't Send Emails

If you're having trouble sending emails, you can contact OIT for support. To expedite your request, please provide the following information:

  1. When did the issue begin?
  2. Name, email address, or UCInetID of the person you are trying to email.
  3. Did you receive a bounceback? If so, what was the error message?

Failure to provide the above will delay your request. When you're ready, open a ticket.

Not Receiving Emails

If you're having trouble receiving emails, visit What's My Email? and confirm your email delivery point is set correctly (e.g. if you use UCI Gmail, it should be set to @gmailbox.es.uci.edu). If it says something else (e.g. @es.nacs.uci.edu), that would explain why you're able to send mail from UCI Gmail but not receive it there.  On the What's My Email? page there is a link to instructions on how to change your email delivery point. NOTE: If your email delivery point is set to @exchange.uci.edu or @hs.uci.edu, you will NOT be able to change it yourself. Open a ticket with the OIT help desk and we'll investigate whether or not it can be changed. Those delivery points are intentionally set by your department and there's probably a good reason why you shouldn't change it. If you're still having trouble receiving email, you can contact OIT for support. To expedite your request, please provide the following information:

  1. When did the issue begin?
  2. Name, email address or UCInetID of the person trying to email you.
  3. Did the sender receive a bounceback? If so, ask them to forward it to an alternate email address you own.

Failure to provide the above will delay your request. When you're ready, open a ticket.

Someone from off-campus can't email me; says their email is 'blocked due to excessive spam.' What does that mean?

If a non-UCI user is having difficulty sending an email to someone at UCI, it may be because their email domain (e.g. @example.com) is blocked by our security team. The sender will receive a bounceback email notification telling them they've been blocked 'due to excessive spam.' You can review this KB article to learn why these blocks happen. We can open a ticket requesting that the email domain in question gets unblocked. We need details such as the email address that's blocked (e.g. joe@example.com), and the approximate date and time when the sender received the bounceback email notification. Without this vital info, we cannot lift the block.

How do I set an out-of-office/vacation reply?

It varies, depending on the email system you use:

How does OIT help protect the campus from spam?

We have a great overview of how OIT deals with spam as well as some impressive statistics.

How do I setup my email client to search the campus directory (LDAP)?

We have detailed instructions on how you can configure an desktop email client (like Thunderbird or Apple Mail) to search the UCI Campus Directory.

What is the maximum file size for attachments?

The maximum file size is about 22MB. (Technically the limit is 30MB but when an email is sent it can grow by about 30% due to encoding and headers.)

If you must share a large file via email, it's best to use either Webfiles or another UCI-sanctioned cloud-based service (like Google Drive) to host the file, then send a link to the file.

How do I use my My.Name alias in Webmail?

After your My.Name alias (such as peter.anteater@uci.edu) has been approved, you will need to publish this address in the directory if you have not opted to do so already. Directory changes happen overnight, so please allow up to 24 hours for this change to take place. Once your My.Name alias is showing in the directory, your "from address" will automatically update to be the My.Name alias, though you may still see your UCInetID as your address in the Webmail interface itself. Rest assured that the receivers will see your My.Name alias as intended.

Note: If your recipients are still seeing your UCInetID as your name, you will need to update your display name in Webmail. 

I've tried the steps above and I'm still having issues

We recommend you continue your search in our comprehensive ServiceNow Knowledge Base.

If you're still having trouble, feel free to open a ticket. When doing so, please provide the following:

  • Your full name
  • Your UCInetID (the first part of your email address, not your ID number)
  • A detailed description of the issue

Failure to provide this information will delay our response.
