Need to install 32 bit outlook from office365 on windows 10 pc

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.

Let us know if you need more specific information.

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:

Hi Tony&Rohn007,

Sorry for my careless. As Rohn007 mentioned that the 64-bit version of Office is installed by default now. And it is supported to install 32-bit Office as well. (Running 32-bit and 64-bit versions of Office on the same computer isn’t supported).

To install the 32-bit Office, you can sign in to www.office.com and select Other install options, choose the language and version you want (64 or 32-bit), and then select Install.
