Hi @cheryl, thanks for your question. We have a number of threads about how to resolve outlook install errors, and each is specific to the particular error you are seeing. I would recommend searching for the term "outlook install error" and then you should be able to find the instructions to resolve what you're seeing. If there is not a post about the specific error you are seeing, please upload a screenshot here.
