Looking for a way to get Microsoft Office 365 Pro Plus on up to five devices without paying an annual subscription fee? Wincdkey offers a Microsoft Office 365 Pro Plus Lifetime Account for 5 devices — a one-time purchase that gives you access to the full Microsoft 365 application suite across your PC, Mac, tablet, and smartphone, with no recurring charges.

This page covers everything you need to know: what’s included, how it works, how to set it up, and how it compares to other Office licence options available at Wincdkey.

What Is the Office 365 Pro Plus Lifetime Account?

The Office 365 Pro Plus Lifetime Account is a pre-configured Microsoft account that comes with an active Office 365 Pro Plus subscription already applied. Unlike a standard Microsoft 365 subscription that requires annual renewal, Wincdkey manages the renewal process on your behalf — so you pay once and don’t need to worry about expiry.

When you purchase, you receive a username and temporary password to log into your Microsoft account at login.microsoftonline.com. From there, you can download and install the full Office suite on up to 5 PCs or Macs, plus up to 5 additional mobile devices (tablets, Android, or iPhone).

Key things to understand about this product:

• This is a shared tenancy account — it comes with a pre-generated username that cannot be changed
• Microsoft requires you to change the temporary password on first login — choose a strong, unique password and keep it safe
• The account is managed and renewed by Wincdkey, so your access remains active long-term
• No CD, box, or physical media — installation is entirely digital, downloaded directly from Microsoft

What’s Included: Office 365 Pro Plus Applications

Once installed, you get access to the complete Microsoft 365 Pro Plus application suite. This is one of the most comprehensive productivity packages Microsoft offers, including:

• Word — full-featured word processing with advanced formatting, styles, and collaboration tools
• Excel — powerful spreadsheets with pivot tables, Power Query, and data analysis features
• PowerPoint — professional presentation creation with transitions, animations, and Designer
• Outlook — email, calendar, contacts, and tasks management
• OneNote — digital notebook for capturing notes, ideas, and research
• Teams — video conferencing, chat, and collaboration hub
• Publisher — desktop publishing for flyers, newsletters, and marketing materials (PC only)
• Access — relational database creation and management (PC only)
• SharePoint — team sites and intranet for document sharing and collaboration
• OneDrive — 1TB cloud storage per user for file access from any device
• Forms, Power Apps, Power Automate, Stream, Yammer — extended productivity and automation tools

All applications are always kept up to date automatically — unlike a one-time perpetual licence such as Office 2021 Pro Plus, you always have the latest feature releases as part of your subscription.

Device Compatibility

The Office 365 Pro Plus Lifetime Account for 5 devices supports installation across a wide range of platforms:

You can manage which devices are licensed through your Office 365 dashboard. If you need to move a licence from one device to another, simply remove it from the old device and add it to the new one — as long as you haven’t exceeded the 5-device limit for PCs/Macs.

Running Windows 11 or Windows 10? Both are fully supported.

How to Set Up Your Office 365 Pro Plus Lifetime Account

Getting started is straightforward. Follow these steps after purchase:

1. Check your email. Once your payment is confirmed, you will receive your account username and temporary password by email — typically within minutes.
2. Log in to your Microsoft account. Go to login.microsoftonline.com and enter the username and temporary password provided.
3. Change your password. Microsoft will prompt you to set a new password on your first login. Choose a strong, unique password and store it securely — this is the only way to access your account.
4. Install Office. Once logged in, click Install Office (or Install apps) from the top right of your Microsoft 365 dashboard. Select Office 365 apps to begin downloading the installer.
5. Run the installer. Open the downloaded file and follow the on-screen instructions. Office will install and activate automatically using your account credentials.
6. Repeat on additional devices. Log in to login.microsoftonline.com with the same account on each device you want to activate Office on, and repeat the install process.

Important Notes Before You Buy

• Uninstall older Office versions first. If you have Office 2016, Office 2019, or any other version installed, uninstall it before installing Office 365 Pro Plus to avoid conflicts.
• The account username is pre-generated and cannot be changed. This is a shared tenancy account — only the password can be modified.
• Keep your password safe. If you lose access to your password, account recovery may be difficult. Store it in a secure password manager.
• Internet is not required for day-to-day use. A common misconception — you do not need a permanent internet connection to use Word, Excel, PowerPoint, or other desktop apps. An internet connection is only needed for installation, activation, and cloud features like OneDrive sync.
• 1TB OneDrive storage is included and accessible from any browser or the OneDrive app on any device.

Frequently Asked Questions

Is this a genuine Microsoft Office 365 account?

Yes. The account is a real Microsoft 365 Pro Plus subscription account. It gives you access to official Microsoft software downloaded directly from Microsoft’s servers and includes full access to all Office 365 Pro Plus applications and cloud services.

Do I need an internet connection to use Office 365 Pro Plus?

An internet connection is required during installation and activation, and for cloud-based features such as OneDrive sync and real-time collaboration. However, the desktop applications — Word, Excel, PowerPoint, Outlook, etc. — work fully offline once installed.

Can I use this on a Mac?

Yes. Office 365 Pro Plus is fully compatible with macOS. You can install it on up to 5 Mac devices (or any mix of PCs and Macs, up to 5 total).

What happens if I need to move the licence to a new device?

Log in to your Office 365 dashboard and deactivate the licence on the old device. You can then install and activate Office on the new device. As long as you stay within the 5-device limit for PCs/Macs, this can be done as many times as needed.

Why can’t I change the username?

This is a shared tenancy account, meaning the Microsoft account was pre-configured as part of a managed plan. The username (email address) associated with the account is fixed. You can, however, change the password at any time through your Microsoft account dashboard.

What if I prefer a traditional product key licence?

If you prefer a standard perpetual key that ties to your own Microsoft account, take a look at Office 2021 Professional Plus or Office 2024 Professional Plus — both are one-time purchases with no account dependency.
