Short answer No.
The longer answer is Yes, but not the way you want.
MS was lazy when it created the 64 bit version. They made minor required changes to the program before "compiling" it to 64bit. So all of the program files have the same names. And they installer puts the 64 bit program files in exactly the same place as the 32 bit files. But 32 bit programs cannot use 64bit sub programs. What it means you can only have 32 or 64 bit Office installed, not a mix.
You will have to uninstall 64 bit Office, then install 32 bit Office, including Outlook.
This is not a problem. Your license allows you to use either version. Simply doing a "normal" uninstall will leave behind configuration information that the next install will pick up so that user sees no difference. There is effectively no performance difference between 32 and 64 bit Office applications. The only difference the user may notice is if they need to use VERY large files, 2-3GB or more. 32 Bit won't handle them.

According to my research, 32-bit Office is recommended for most users because it’s more compatible with most other applications, especially third-party add-ins. This is why the 32-bit version of Office is installed by default, even on 64-bit Windows operating systems.

Sorry Huni, that is old news. Since the new year MS has started to change their default Office install to 64bit
In December 2018 / January 2019 MS started switching default install of Office to 64 bit on 64 bit Windows installations. Here are a couple of articles that talk about the change
Here is the updated MS page that now says they default to 64 bit Office installs:

I never get prompted to pick 32 bit or 64 bit when I install office. How the heck do I do this?
Hi Philip Hoyle
Welcome to Microsoft Community.
I realize that you've encountered a problem with " Install 32 bit version of Office 365 ", and I understand how you feel. Don't worry, I'll do my best to help you.
To install the 32-bit version of Office 365 (now typically referred to as Microsoft 365), you can follow these steps to ensure you download the correct version:
1. Confirm Office is Uninstalled:
- Ensure you have completely uninstalled the 64-bit version of Office 365. You can do this through the "Control Panel" under "Programs and Features." Also, delete Office configuration files, which are usually stored in the following directories: C:\Program Files\Microsoft Office C:\Program Files (x86)\Microsoft Office
2. Use the Office Deployment Tool:
- If you cannot correctly download the 32-bit version from the official website, you can try using the Office Deployment Tool to manually configure the installation:
- Download the Office Deployment Tool.
- Create a configuration file specifying that you want to install the 32-bit version of Office:
3. Save the configuration file as and run the command line tool to install Office using the deployment tool.config.xml
3. Check for Cache or Browser Issues:
- Try downloading in incognito mode or clear the browser cache and then download again, or try using a different browser. Sometimes browser cache can lead to downloading the wrong version.
Feel free to share updates with me on how things are progressing after you've completed the aforementioned steps. Should you have any questions or require clarification, do not hesitate to reach out to me. I‘d like to do my utmost to assist you.

I am having exactly the same problem installing the 32 bit version of Office 365. This creates a big problem for me because I need to create a 32-bit Access .accde file and it is only possible to do that using the 32 bit version of Access (in Office 365). Microsoft technical support worked on it with me for about three hours. They verified that the problem exists but they were not able to solve it.
I am trying to install Office 365 on a Windows 11 ARM VM running in Parallels on an iMac computer that has an Apple silicon chip. Since Windows 11 ARM is compatible with both 32-bit and 64-bit applications, it should be possible for the 32-bit version of Office 365 to work under those conditions. However, Office 365 is a Native ARM64 App and perhaps the Office 365 installation process is intentionally switching over to installing the 64-bit version for that reason. If that is the case, Microsoft really should issue an informational message to let you know what's happening instead of just ignoring your installation instructions.
