What you need to do

  1. Disable digital signature: If you use a digital signature, disable it. UITS no longer recommends digital signatures at IU. Disabling your client certificate before your primary email address is changed to will avoid any potential issues when the change occurs.
  2. Identify your campus-specific email addresses: Identify what campus-specific email addresses you have at
    You may have campus-specific email addresses you are unaware of.
  3. Your primary email address: If your primary email address is not already set to, you can change it yourself, or wait for UITS to change it administratively on a date to be scheduled for each campus domain.

    To change your primary email address to your address, visit Manage Your Email. With this change, your sent emails will come from your address and your address in the Global Address List will be changed to your address.

    For more, see Change your primary email address.

    • Your calendar entries may momentarily disappear at the time of this change, but will be restored quickly.
    • Some users have reported problems in sending and receiving email immediately after the change, but this typically resolves itself in about ten minutes. Exiting and restarting Outlook and/or restarting your computer may be helpful if the issue persists.
  4. Direct mail sent to your campus-specific address(es) to a separate folder: You can create a rule to automatically direct any emails sent to your campus-specific address to a separate folder, so that you can monitor the folder for action at your convenience. For instructions, see below.
  5. Make use of your weekly email report: As this project progresses, you'll begin receiving weekly emails listing the "From" address of all messages sent to your campus email address. These weekly messages will help you identify senders you can notify that your email address is changing to To notify these senders:
    1. Open a new email message in Outlook. Enter "Email address change" or something similar in the "Subject" line.
    2. Select Options and then Bcc. From the message you received, copy and paste the email addresses of those you wish to notify about your email address change into the "Bcc" field.
      You don't need to include addresses that send internal mass communications, such as or; these senders will automatically update to use your address before the campus domains are discontinued.
    3. Add text in the body of your message to notify these recipients that your email is changing, for example:
      My email address is changing to Please update my contact information accordingly and send future email to me at this new address.
    4. When you're ready, send the message.
  6. Add a signature block to your outgoing emails: Add a signature block to your email notifying your mail recipients that your email is changing to
  7. Eduroam: Be sure to update your eduroam login; see Connect to eduroam.
  8. Egencia: If you have an account with Egencia (IU's preferred travel management system), follow the instructions to review and update your profile.
  9. TimelyCare: If you have an account with TimelyCare (the virtual health and well-being platform for IU's students), email the Office of the Chief Health Officer at so they can work with you and TimelyCare to update your account.
  10. Third-party accounts: Review and change any accounts with third-party services or agencies that use your IU campus-specific address as your login or email contact. For services unrelated to IU (such as Netflix, Apple ID, utility bills, social media accounts, etc.), UITS recommends changing the account to use a personal email address.

    For details about some services that many IU employees may have a relationship with, including insurance and retirement accounts established through IU Human Resources, see Update your IU email address for third-party services.

  11. IU List: If you own or moderate any lists on IU List, review Changes to IU List from the One Mail initiative. A privileged owner will need to migrate each list.
    If you're subscribed to mailing lists on IU List with your primary email address, your subscription address will be changed administratively at the same time as the administrative primary email address change for your campus domain or department, and no action on your part will be required. However, if you previously changed your primary email address without updating your IU List subscriptions, the address will need to be changed manually. Also, addresses for discussion lists and self-service IU List features will change. For more, see Changes to IU List from the One Mail initiative.
  12. External mail lists: Review any external email lists you subscribe to and modify your subscription to your email address.
  13. Published research: If you have published research or have submitted research to a publisher for future publication, and your campus-specific address is listed, be sure to update your contact information with the publisher. For more, see below.
  14. Remove your campus-specific address(es): When the preceding steps have been addressed, and you are certain you are no longer receiving mail you want to see at your campus-specific email address, you may choose to remove your campus domain address yourself at If you do not remove it yourself, it will be removed administratively according to the established timeline. Once your campus domain email address is removed, mail sent to that address will generate a bounce message to the sender.

Update your contact information for published research

If your campus-specific address is listed in past or forthcoming research publications, the following suggestions will help you update your email address with the publisher:

  • Check the publication's website: Visit the website of the journal or conference where your paper was published. Many publications provide contact information for authors, and you may find details on how to update your contact information.
  • Contact the publisher: If your paper was published by a reputable publisher, contact them directly. Publishers often maintain records of authors and may assist in updating your contact information.
    Graduate students should talk with the PI before contacting the publisher.
  • Collaborate with co-authors: If you have co-authors, check whether any of them can still be reached through the original email address or if they have information on how to update contact details.
  • Online researcher profiles: Create an ORCID iD, and make sure your contact information is up to date there. This can serve as an additional means of communication. Find more information on managing your research identity at Open Scholarship (IUB Libraries) or ORCID @ Indiana University Indianapolis.
  • Update your school or department faculty profile page: Update your contact info to list your address as your primary contact, leaving your campus-specific address with a note that it is a previous email. This will help web searches connect you with your previous campus email address and any works, publications, or related materials.

Create a rule to collect email sent to a campus-specific address

If you like, you can create a rule in your Exchange account to route all messages sent to your campus-specific address into a specific folder in your mailbox, in order to more easily track and collect those messages:

  1. Open Outlook on the web and log into your account.
  2. From the Settings menu (Settings menu icon) in the upper right, select Rules.
  3. Choose + Add new rule.
  4. Enter a name for the rule that will remind you what it is, such as mail.
  5. Under "Add a condition", select Message header includes, and then in the prompt to the right, type your campus-specific address, for example (replacing "username" with your username).
  6. Under "Add an action", select Copy to. In the box to the right, scroll down to "Create new folder" and type the name of the new folder you'd like that mail stored in, such as
  7. You can choose to stop processing more rules, or uncheck the box if you have other rules you'd like to apply to mail.
  8. At the bottom of the dialog, choose Save.
