Download Office 365 Offline Installer ISO/IMG File (March 2024)

There is no official way to download the ISO image of Office 365 to install multiple Windows computers. Let's check it out how to tweak the online installer to get the offline one.

Do you want to Download Office 365 ISO? Due to some problems, yesterday I installed a clean version of Windows. The first software I need as a blogger is Microsoft Office.

I have an active subscription to Office 365, but it comes with an online installation. If you have a slow Internet connection like mine, then you can’t afford the online installation process. That’s why I always prefer Office 365 offline installer or ISO image files.

There is no official way to get a Microsoft Office 365 standalone installer. You can download Office 2016 ISO, and you’ll get Office 365 as an option in that, but the file size is more than 4 GB.

If you install 365 through the online installer, it’ll not be more than 2 GB. The 32-bit version is around 1.7 GB, and the 64-bit is 1.9 GB. Then why should you download the extra GBs? Let’s know more about Office 365 Offline Installer.

How is Office 365 Different from Other Office Versions?

Office 365 is a subscription-based application to access Office applications (Word, Excel, PowerPoint, OneNote, Outlook, Publisher, and Access) as well as productivity services over the Internet. There are two types of plans for Home and Business users.

Why Download Office 365 Offline Installer?

The answer is very simple. If you have five computers and you want to install Office 365 on all of them, then it’ll take at least 10GB of data, and the most important thing is the time.

The offline is very handy if you have purchased the Personal plan. Once you have downloaded the offline ISO or installer, you can install it as many times as you want, but at most on 5 PCs. Well, without taking more time, let’s come to the download process.

To begin the process, you need the Office 2016 Deployment Tool. You can download it here.

2. Run the Office Deployment Tool and extract the files in the created Office365 folder. There are two files in that folder; setup.exe and configuration.xml

3. Open configuration.xml in the text editor and change the like this and save it:

<Add SourcePath="C:\Office365" OfficeClientEdition="64" Channel="Monthly">
<Product ID="O365ProPlusRetail">
<Language ID="en-us" />
<Updates Enabled="TRUE" Channel="Monthly" />
<Display Level="None" AcceptEULA="TRUE" />
<Property Name="AUTOACTIVATE" Value="1" />

You can change the bolded red lines according to your preference.

SourcePath: Where the files you want to save.
OfficeClientEdition: If you need the x86 client version then change it to 32
Product ID: There are three types of products; O365HomePremRetail, O365BusinessRetail, and O365ProPlusRetail
Language ID: If you need another language package

4. Once everything is done, open the command prompt and run the below command to begin the downloading process.

First, you have to navigate to the created folder by typing the command,

cd c:\Office365


setup.exe /download configuration.xml

5. The download will begin, and a new subfolder “Office” will automatically be created in the C:\Office365 folder.

6. Once the file has been downloaded, run the below command to start the installation process.

setup.exe /configure configuration.xml
