If you are talking of VSTO addin, it depends on what version of office com libraries you refer in the project. You may have to go through the below link:Develop outlook add-in compatible with multiple versions

Alternatively, you can use add in express toolkit to build one Addin targeting multiple MS office versions.https://www.add-in-express.com/
