Under all circumstances, stay away!

It is not possible for me to install this "product". The network has been running for years about error messages and non-functional fixes for "Office 365" software. These are partly absurd complicated, just the sebst-Microsoft instructions. The problem seems to be that action is taken unusually deep into the system during installation to allow for "more convenient online experience" - with the result that with any great effort can never completely remove it from the computer, the software again and consequently does not have 2nd attempt. The error messages like "Oops, there has not worked out what" go the extra mile to prevent successful troubleshooting.

Conclusion: See heading!
