I have a client who runs an Exchange 2013 on premises organization, with multiple MBX servers in a cross site DAG, multiple CAS behind a HLB.
Recently, the client acquired another company named company X, this company only has 5 contractors and their request is to have these 5 employees to use outlook with their own email domain. We have repointed their MX records to our MX records, we created an authoritative email domain, and next step would be to setup their outlook.
The challenge that we have is that the business does not want to allow these 5 contractors to use our email systems and have the same email policies, and they asked me to evaluate 3 different approach to manage their email:
What I need from your expertise, is number one, PROS and CONS of using any of the approach below, and the infrastructure required for each approach:
1. Setup in Go daddy email accounts, then setup outlook to use these email accounts, is this option feasible? can we manage their emails with this option?
2. Setup Google apps for these 5 users, and install connector for outlook clients. their email will reside in the cloud, and we should be able to manage their email through Google Apps. is this option feasible? from internal architecture what is required to be deployed?
3. Setup a hybrid Exchange Office 365 with our existing exchange 2013 deployment. Please, provide all components required to complete this requirement
Please, understand this is a consulting question, that requires as much information as you can provide.
