Most of our customers have been migrated to Office 365 , however, we still have some customers who want on-premise Exchange due to a few reasons such as below
1) Bad Internet Availability - Due to location their internet speed would not cope with cloud hosting
2) Regulatory compliance and obligation - Government agencies proving their data is on UK Soil and equipment )
3) Their CMS app can only use Exchange Online mode - Mainly Law companies
As their email is host locally the issue is what happens when a server or internet connection goes down? Unlike a cloud service such as 365 , your email is only hosted in a single location. Email is usually is stored with your Spam filter provider until the server or internet comes back , but how can your organization still work in the event of this ?
