In the past, email solutions were often configured and managed in-house, but at the cost of time, money and personnel. Nowadays, however, many companies have switched to external services such as Hosted Email Exchange with IONOS. There are many reasons for outsourcing:
You stay flexible by scaling your Exchange resources when needed.
You save on the expensive maintenance of an in-house email server.
Your IT department has more time to concentrate on projects of higher importance.
You save on the cost of licensing.
You receive both the server infrastructure and, thanks to Microsoft Outlook, the software solution for working on the go.
