I understand you're looking for a highly compressed (100 MB) version of Microsoft Office 2016, but I need to provide an important clarification:
No legitimate or functional copy of Microsoft Office 2016 exists at 100 MB.
The actual installed size of Office 2016 is 2–3 GB. Even compressed installers are typically 600 MB–1.5 GB.
If you’ve seen claims like "Office 2016 Highly Compressed 100 MB Fixed" on YouTube, torrent sites, or forums, these are almost certainly: ms office 2016 highly compressed 100mb fixed
Standard ZIP compression typically reduces file size by 20–40%. A 3 GB folder compresses to about 2 GB. Specialized compression tools like 7-Zip (LZMA2) or KGB Archiver can achieve 50–60% compression on certain file types, but only on highly redundant data (text files, logs). Office executables, DLLs, and font files are already optimized and partially compressed. You cannot reduce 3 GB to 100 MB using any lossless compression algorithm. Lossless compression ratios beyond 95% are mathematically impossible for binary executable files.
Even the lightest legitimate installation of Office 2016 requires around 1.2 GB. However, you can install it on an external USB 3.0 drive or a secondary partition. Install Office using the deployment tool: I understand you're looking for a highly compressed

While slightly larger, WPS Office includes a tabbed document interface and full support for .docx, .xlsx, and .pptx. The free version has ads, but it's legitimate and lightweight.
