Problem

In Microsoft Office 365, you receive an error message that's like the following in the Microsoft Office 365 portal:

8 Things Microsoft Office 2016 is Great for as a Productivity Suite; Message error: '.the specified Product key has already been activated the Maximum number of times' Online activation did not work - the product key used maximum number of times permitted message; How to Change Product Key in Office 2010 Without Uninstalling.

  1. This product key has already been used. If you see this message, it's because your product key has already been redeemed on this site. To install Office or manage your account, go to Microsoft account, Services & subscriptions page and sign in using the account that you used to buy or subscribe to Office.
  2. But after installation, when I open any of Office programs, the installed Office program gives me a notice 'Your copy of Microsoft Office Professional Plus 2013 cannot be activated because the specified Product Key has already been activated the maximum number of times for your software license', which is not true!
  3. If you receive an email sent to your work address that contains a product key, follow the instructions in Get help installing Office through Microsoft HUP. If you don't receive an email (and it's not in your junk mail), check to see if your Office product is listed on your Microsoft account, Services & subscriptions page.
  4. Examples of using the wrong product key. Most Microsoft products use a 25-character product key. If you own multiple Microsoft products, it’s easy to confuse the keys and use the wrong one. Here are some common things that can happen: Using the product key from a sticker on a PC. These product keys are normally for Microsoft Windows.

A user with this name already exists. Use a different name.

Cause

This issue may occur if the user name is already used or if an existing email address that's based on the user name already exists.

The licensing attempt will fail if the provisioning process determines that another object already has a user name or an email address that matches the user name that's being created.

By default, when users are added or assigned an Exchange Online license, the users are provided with a primary SMTP address that's based on their user name. And, users are provided with an email address that's based on the Microsoft Online Direct Routing Domain (MODRD) such as, for example, contoso.onmicrosoft.com. Additionally, when a user name is changed, the primary SMTP address may also be changed. However, alternate addresses aren't updated or removed.

Here are some example scenarios.

Scenario 1

Scenario 2

A user is added who has a user name of john@contoso.onmicrosoft.com, the MODRD for the organization is contoso.onmicrosoft.com, and the user is assigned an Exchange Online License. In this scenario, the following email address is provided:

  • The user is provided with a primary SMTP address that's john@contoso.onmicrosoft.com.

Scenario 3

A user name is changed from john@contoso.com to johnsmith@contoso.com. In this scenario, the following events occur:

  • The primary SMTP address, john@contoso.com, may be changed to johnsmith@contoso.com.
  • The alternate email address, john@contoso.com, isn't changed. Therefore, problems occur if you try to add john@contoso.com later.
  • No alternate email address for johnsmith@contoso.onmicrosoft.com is created.

Solution

To fix this issue, do one or more of the following:

  • When you add a user, use a different user name.
  • When you add a user, find and change the existing user name so that you can use the user name with which you are experiencing the issue.
  • When you add or assign a user to an Exchange Online license, find and change the existing email addresses that are based on the user name that you are trying to use.
