One of my favourite features is the Microsoft Calendar, which we use for booking appointments, scheduling calls, and managing resource rooms and devices. The Online Mailbox feature is also crucial because it allows us to communicate effectively within and outside the organization, contributing to our business growth.

My personal issue with using OfficeSuite and the Exchange Server is that one has to cobble together a whole bunch of different applications. Therefore, a lot of scripting and programming knowledge is necessary.

In terms of areas for improvement, I think Microsoft could enhance security. Right now, there are limited options for security within Exchange Online, and much of it relies on third-party security and compliance tools. I'd like to see more security features directly integrated. One specific area that needs improvement is the configuration of SMTP for third-party applications. It's challenging to manage without an on-premise SMTP server, and this is an issue many organizations face, including ours. If Microsoft could offer better SMTP configuration for third-party applications within Exchange Online, it would greatly benefit us.

The configuration of the solution's on-premise version is a little bit difficult, and its troubleshooting is more difficult than the installation itself.
