Can You Delete the Microsoft 365 Offline Installer After Installation?
Question details
The user wants to know if it is safe to delete the large Office 365 offline installer file once the installation is complete, and how subsequent software updates are managed.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Freeing up disk space after successfully installing Microsoft 365 from a large offline installation package.
- Observed behavior
- The user needs clarification on whether deleting the setup file affects future updates or the ability to use the Office applications offline.
Ensure that your Microsoft 365 installation is fully completed and that you can successfully open applications like Word or Excel before deleting any setup files.
Safely Delete the Offline Installer File
Once Microsoft 365 is installed, the offline setup file is no longer needed and can be deleted to free up local disk space.
The offline installer is simply a delivery mechanism for the application files. Deleting it will not affect your installed Office applications. Future updates are delivered automatically via the internet directly through the installed apps.
Open your computer's 'Downloads' folder or the specific directory where you saved the Office 365 offline installer (usually an .img, .iso, or .exe file).
Right-click the installer file and select 'Delete' or move it to the Recycle Bin/Trash.
To permanently free up the disk space on your hard drive, right-click the Recycle Bin or Trash icon and choose 'Empty'.

Frequently Asked Questions
How does Microsoft 365 get updates if I delete the offline installer?
Microsoft 365 updates itself automatically over the internet. The installed applications periodically check Microsoft's servers for updates, meaning the original installer file is completely unnecessary for receiving future software patches.
Do I need a constant internet connection to use Microsoft 365 apps?
No. Once installed, applications like Word, Excel, and PowerPoint run locally on your device and can be used offline. However, you do need to connect to the internet at least once every 31 days to verify your subscription status.
Can I copy the offline installer to a USB drive instead of deleting it?
Yes. If you have multiple computers to install Office on, or if you want a backup due to slow internet speeds, you can safely copy the offline installer to a USB flash drive or external hard drive before deleting it from your main computer.
