Common Microsoft Office 365 admin Installation Errors

Microsoft Office 365 is a really neat tool that gives you all you need to start a mini office anywhere and anytime you want, provided that you have computer access. 

With Office 365 installed, you can gain access to not only Microsoft Office's famous programs but also to new cloud-based features that are set out to change the way you work on your PC.

Like all things, Office 365 can have some errors, especially during the installation process. 

While some can be fixed quickly and easily, others can be problematic and might require further attention to fully deal with them. 

To help you handle these problems, we have compiled a dedicated troubleshooter for Office 365. 

Here is what you should do when you encounter problems with Office 365

Administrative privilege required


Before you begin, it is recommended that you check Exchange 2007 End of Support Roadmap. This service is included in Office 365, but since it has reached the end of support, you shouldn’t expect much help from the support staff.

When there is trouble, it is important to determine which plan you have subscribed to, Office for home or Office for business. 

The issues you may encounter, along with the solutions to each of them, are highly dependent on the plan, so it is a good idea to check beforehand. 

Additionally, if you are the admin of Office 365 for your organization, your responsibility, along with your rights, will expand a bit as you will be able to do a few extra tasks. This means that you can take one step further to troubleshoot your organization’s Office 365. 

This guide will mainly concern your tasks and issues as an admin.

Try this before you start

Before you start diagnosing your Office 365 problems by yourself, it is a good idea to check out the Support and Recovery Assistant for Office 365 tool. 

This tool, which is available for free download, will automatically diagnose and troubleshoot Office 365, allowing you to save a lot of time. 

If the recovery tool could not help you get rid of the problems at all, it’s time to dig deeper into other troubleshooting tasks.

You are the admin and there is no option to install Office, Project, Visio

Having the license is the first important step to install your Office, but in some cases, even if you do have the license, there is still no option to install the software. The reason they give you is that because you don’t have a license! 

This issue happens due to a delay in the server, and your license has not been registered yet. To fix this, you could log out then log back again. The problem should be fixed by now.

If it is not fixed, perhaps you have not assigned the license to either you or others. The first step you should take now is to check your license to see if it has been registered or not. You can do the following step to check your license.

  1. Check to see if you have a license
  2. Go to and sign in with your account. Be noted that if you cannot log in to your account, it is likely that you have signed in to the wrong Office 365 Service.
  3. Go to Settings, then My App Settings, then Office 365.
  4. Choose Subscriptions on the My account page.
  5. You will then see the licenses that you own listed on the page, including licenses for Office, Project, Visio, etc. You should also be able to see The latest desktop version of Office in the list. If you don’t, consider assign licenses to other users.

Do note, however, that not all Office plans come with all Office applications. 

Some only include the most essential applications. To see which plans will include a fully installed version of Office 365, check out the bottom of Office for a business page. 

As an admin to Office 365, you have full rights to change to another subscription plan if your organization happens to be using one of the incomplete plans. Additionally, aside from the plans you already have, you can actually buy a new plan which includes a full installation of Office for those who need it in your organization,

You recently switched plans and now you suddenly received a message that you can’t use Office anymore

When you switch the plan for your Office 365, a new installation is often required to apply the new changes. If any user in your organization sees an error notice regarding this matter, you could assist them in deleting the old version and installing a new one with the new plan integrated.

Microsoft Office takes forever to install

MS Office can encounter an error or delay in the download process when you attempt to install the application. To avoid wasting time, we recommend that you should use Office offline installer to finish the installation process.

Installing the latest version of Office on more than 5 computers

Upon receiving the license to use Office, you will be allowed to install the application on 5 computers at max. If you want to install Office on a sixth computer, you will have to deactivate the license on one of the 5 other computersThis does not mean that MS Office will be uninstalled on the said computer, it just simply means that you will not be able to use Office until the license is reactivated.

Setting up your organization with Office 365 for business

Setting up your organization for Office 365 for business can be quite a tricky task, so it will be covered in a separate topic.

Upgrading Office to the latest version for users in your organization

Using old versions of Office is not recommended. If there is an outdated user in your organization, you should help them to update to the latest version to ensure the best user experience.

Deploying Office to multiple computers in your organization

This step should only be done by IT pros since it can involve some bits of tweaking. The tool you want to use for this task is Office Development Tool, which allows you to download Office applications to your local network. Afterward, you will be able to deploy Office to all computers within the network using your usual network development method.

Alternatively, you can ask everyone to install their own Office by signing in to Office 365 portal using their accounts. They will then have to follow some steps to install Office on their own PC or Mac.

Managing licenses for your organization

Every Office user needs a license in order to gain access to the application. As the admin of your organization’s licenses, you will be in charge of managing these licenses

When a new user installs Office 365, it will be your responsibility to assign a license to them. Alternatively, if a user has requested another license, you will have to assign them with a new one. If a user does not need a license anymore, you can remove their license to allocate this license to a new user.

If the organization should require more licenses, you can buy more as well. Conversely, if there is no need for a license and the organization wishes to remove it, you can do it as well.

Activating volume license editors in Office

As the admin, you will also be in charge of activating the licenses of volume editions of Office. There are two ways to do this, either by Multiple Activation Keys or Key Management Service. This step will be covered in detail in another article.

Viewing the status of your services

Checking the status of your services is the first step to ensure the continued use of Office services. As the admin, you will have to constantly monitor the status of your Office 365 service health. 

You can accomplish this by using Microsoft 365 Admin Center.

Troubleshooting for Outlook, Skype for Business, or OneDrive for Business

This article only deals with Office 365’s installation issues. However, there are also other support pages for specific issues with each of Office 365 services, including Outlook, Skype for Business, and OneDrive for Business. If your problems are non-specific to the role of admins, then you should check the general troubleshooting article for Office for Business.
