Before deploying 365 Apps to lớn users in your organization, you must first assign licenses to those users. Each license allows a user khổng lồ install 365 Apps on up to five desktops, five tablets, and five mobile devices. Each installation is activated & kept activated automatically by cloud-based services associated with Office 365 (or 365). This automatic activation means you don’t have to keep track of product keys & you don’t have to lớn figure out how lớn use other activation methods such as Key Management Service (KMS) or Multiple Activation Key (MAK). All you have to vày is purchase enough licenses, keep your Office 365 (or 365) subscription current, & make sure your users can connect to lớn the Office Licensing Service via the internet at least once every 30 days. When single sign-on is enabled, 365 Apps detects the user’s credentials and is activated automatically.

If you remove a user"s license (for example, if the user leaves your organization), any installations of 365 Apps that the user had will go into reduced functionality mode. The Office Licensing Service, a part of 365, keeps track of which users are licensed and how many computers they"ve installed Office on.


To activate 365 Apps, TLS 1.2 must be enabled by default on the operating system. Some older operating systems, such as Windows 7 Service Pack 1 (SP1) and Windows server 2012, need an update applied to enable TLS 1.2 by default.

To use 365 Apps, your users will need the appropriate license. To lớn assign licenses, vị one of the following:

Assign a license lớn a user directly in the Office 365 portal by selecting a check box on the licenses page for the user’s account.

After a user is assigned a license, you can deploy Office to your users or your users can install Office directly from the Office 365 portal. If the user hasn"t been assigned a license, the user can"t install Office from the Office 365 portal. We recommend assigning the license 24 hours prior khổng lồ the deployment so you can ensure that the license is provisioned.

Licensing Modes

There are various licensing modes that can be used with a supported version of 365 Apps.

Subscription User Based Licensing

This is the default licensing mode for 365 Apps. In this mode, the license is carried within the user’s profile. With a single license, users can install and activate 365 Apps on up to lớn 5 desktops/laptops, 5 tablets, and 5 điện thoại devices.

Shared Computer Activation

Organizations use an array of tools lớn connect applications và processes together, including frameworks automating other applications. These automation processes may be unattended in their operation and leveraging traditional user accounts is not best practice.The Unattended License allows for the use of Office with service accounts or other non-user accounts, typically common for automation process execution.


Office applications are not specifically designed for large scale unattended usage scenarios. For more information, see Considerations for Unattended Automation of Office in the 365 for Unattended RPA Environment

Viewer Mode

More Information

This mode can be used when your organization has users that only need view/print capabilities instead of full create or edit capabilities. This allows unlicensed users of 365 Apps to lớn view and print Office files without being prompted to activate Office. When Word, Excel, or PowerPoint are opened, users see a banner message underneath the ribbon in their Office apps that informs them that Office is in Viewer Mode.This is an ideal mode when the users have an Office for the website license but not a 365 Apps license.

Activating 365 Apps 365 Apps communicates with the Office Licensing Service và the Activation and Validation Service lớn obtain và activate a product key. Each day, or each time the user logs on lớn their computer, the computer connects to the Activation & Validation Service lớn verify the license status và extend the sản phẩm key. As long as the computer can connect to the internet at least once every 30 days, 365 Apps remains fully functional. If the computer goes offline for more than 30 days, 365 Apps enters reduced functionality mode until the next time a connection can be made. Lớn get 365 Apps fully functional again, the user can connect to the internet & let the Activation & Validation Service reactivate the installation, though in some cases the user may have to lớn sign back in first.


Because of its online activation features, 365 Apps won"t work on computers that are completely cut off from the internet. For those computers, we recommend installing Office LTSC Professional Plus 2021 and using a traditional activation method such as Key Management Service (KMS) or Active Directory domain Services.

Managing activated installations

Each 365 Apps license allows a user khổng lồ install 365 Apps on up lớn five desktops, five tablets, và five thiết bị di động devices. The user manages installations in the Office 365 portal.

If a user installs 365 Apps on more than 10 devices, then the device that hasn"t been used for the longest amount of time is automatically deactivated. 365 Apps goes into reduced functionality mode on the deactivated device. Note that this automatic deactivation is only supported for Windows devices at this time.

What is reduced functionality mode?

In reduced functionality mode, 365 Apps remains installed on the device, but users can only view & print their documents. All features for editing or creating new documents are disabled, và the user sees a message lượt thích the following:


The user can then choose one of the available options to reactivate 365 Apps on that computer.

If the user hasn"t been assigned a license, and they try lớn use 365 Apps on a computer where it"s installed, it will be in reduced functionality mode. Also, the user will be prompted to lớn sign in & activate every time they xuất hiện an app, such as Word or Excel.

Improvements in licensing và activation

In 365 Apps version 1910 and later, we made the following improvements:

Users can install 365 Apps on a new device without being prompted to lớn deactivate it on another device. If a user has more than 10 devices with 365 Apps activated, then the device that hasn"t been used for the longest amount of time is automatically deactivated.

When 365 Apps on a device has been deactivated, either from the portal or because a license has been removed, a new user on that device can activate 365 Apps without an error.

When a user activates 365 Apps on a device and a second user signs on to lớn that device, both activations are now displayed in the activation report in the 365 admin center.
