Office 365 (Microsoft 365) license not assigned to the user issue occurs if the licenses limit exceeds, the user is signed in the application with another organization or account, the license is removed for the user, or there are provisioning issues. In this blog, we will be discussing these issues in detail and see how to mitigate the situation as quickly as possible without further interruption to the user and the business.
What Causes the Office 365 License not Assigned to User Issue?
In this section, we will be going through the factors or reasons that could cause the license not assigned to user issue. We will also be discussing the possible solutions to mitigate them.
Licensing limit has Exceeded
Like all systems, Office 365 has a limit on the licenses being purchased or the region where these are used. For example, Microsoft Office 365 Business Premium license has a limit of 300 users and you cannot use more than this limit. If you need to use more, you need to shift from Business Premium to Enterprise licenses, like E3 or E5. Depending on the region, there could be Microsoft services or applications which are blocked/restricted by the region itself.
Other things that could cause this issue include the billing process has failed due to expired card or issues during the payment, the subscription is suspended, and there was an incident where the tenant has been blocked by Microsoft.
Office Apps showing Unlicensed Product
There could be an issue on the client side. It may fail to activate. The common causes for this might be:
- The user is signed in the applications with another organization or a personal Microsoft account.
- There could be cached credentials that are conflicting with the corporate account in the Credential Manager.
When it comes to the machine, there could be instances that:
- The device is not joined to the Azure AD (Microsoft Entra ID) or is not Hybrid Azure AD joined.
- The activation token is corrupted.
- There are too many devices activated (the limit is of 5 devices).
The first thing to do is check the device activation from the Admin Center and possibly sign out from all the Office Apps. Then, confirm that the right user is being used in the activation of the license. Try to re-join the machine to the Entra ID or Hybrid. From the Credential Manager, remove all the credentials and re-authenticate the applications. If all fails, you should create a new Windows User profile to see if the issue can be reproduced.
Other issues would be related to wrong license being assigned to the user or some of the applications have been intentionally disabled from the User portal in the Admin Center.
License has been Removed for the User
There could be a scenario where the user has been given a mailbox but no longer has access to it. There could be a number of reasons for this.
The user has left the company and the license has been removed and the mailbox has been converted to a shared mailbox. The user, when came back to the company, is not able to login or use the mailbox.
For this reason, ensure that the mailbox is not a shared mailbox. If it is, you should convert it to a regular mailbox from the Exchange Admin Center. After this, you need to assign the respective license. This should allow the user to login and access their resources.
Hybrid and Provisioning Issues
In hybrid setup with a local Exchange Server, you would encounter issues with the provisioning of users from the local server to the cloud. The Microsoft Entra Connect could have mismatches when it comes to the attributes to the user. The following are the reasons:
- The mailbox on the cloud doesn’t match the user on the local server.
- A mailbox cannot be moved from the local server to the cloud.
- The GUID doesn’t match the user.
- Misconfiguration of the Hybrid wizard or the Entra Connect on the local server.
These issues can prevent the users from accessing their license or account.
Below are the possible fixes for the problem:
- Recreate the user object from scratch.
- Recreate the mailbox.
- Resolve the synchronization issues between the local server and Entra ID.
- Correct the issues reported by the Entra Connect.
How to Avoid Downtime when Migrating Data?
When the user is using the identity, you should always avoid downtime as much as possible to ensure that the business operations are not impacted. Recreating user account and reimporting the data can be a challenge. This is where Stellar Migrator for Exchange can come in handy. This Exchange migration tool provides a clean and reliable way to migrate the mailboxes with no data loss and with complete integrity.
In scenarios where the mailbox has been partially migrated, hybrid synchronization mismatches, or any other issues with the migration, this Exchange migration tool can provide a structured migration process.
This tool allows migration of user mailboxes, shared mailboxes, public folders, and user archives from local Exchange Server to cloud, local sever to another local server, cloud to cloud, and cloud to local server. The interface is very easy-to-use. The tool shows real-time migration status as well as post-migration reports.
Conclusion
As we have seen above, there are several reasons why you would end up with the issues where the license cannot be assigned to the user, issues with the Entra ID, or synchronization issues. When these issues are fixed, there is still the challenge to synchronize the data. This is where Stellar Migrator for Exchange – a specialized Exchange migration tool can assist in facilitating the process, and reducing the downtime and inconvenience to the users.
