Create users with unique email addresses

For example, you cannot create one user with the email address of if another user has the email address of

Update email addresses of existing users in your Workfront instance

As the Workfront administrator, you must update existing users who have matching email addresses that differ only by case.
To fix duplicate email addresses within a Workfront instance:

  1. Examine any duplicate users and decide which user is no longer needed.

    1. Click the Main Menu icon in the upper-right corner of Workfront, then click Users.

    2. In the Filter menu, select All.

    3. In the View menu, select User Login.

    4. In the Grouping menu, select Nothing.

    5. Customize the User Login view.

      1. Click View > Customize View.

      2. Replace the ID column with the Email Address column.

      3. Rename the View and save it.

    6. Create a new Grouping.

      1. Click Grouping > New Grouping.

      2. Click Switch to Text Mode in the upper-right corner of the page.

      3. Paste the following Text Mode code:


    7. Rename the Grouping and save it.

  2. Do any of the following:

    • (Preferred method) Add a + address to the user’s email address for each additional account.

      Choose this option if a single user in your organization needs access to more than 1 user account. If plus addressing is not supported by your email provider you must provide a separate email account for each Workfront account.

      For example, John Doe can have one user account for his daily-use account and one to use for testing purposes:

    • Change the domain to use a fake domain by appending the following text to the email address:


      For example,John Doe could have the following domains: (These must be unique.)

      • johndoe@workfront.inactive
      • johndoe@workfront.inactive2

      You can no longer log in to these accounts because password resets require a valid email address. These accounts can be accessed only by using the Login As feature.

    • Delete unneeded users

      note important
      Choose this option only for accounts that were created by mistake or for test accounts. This option is usually performed only for accounts with zero or 1 mistaken login. Accounts that have been regularly used should never be deleted.

If you have users in a Workfront instance with matching email addresses that differ only by case, Workfront will contact you with additional information and a timeline when these need to be updated.
