Mimecast Cloud Archive makes it easy to consolidate email, files, and Microsoft Teams data into a single, secure, and scalable cloud storage. It ensures easy access to data, compliance, and data retention, all of which are critical for our business. In addition, it ensures easy e-discovery and it also reduces our IT overhead costs while also saving us costs related to on-premise hardware as it is a cloud solution.

Mimecast support is generally very responsive, I've only had 1 out of many cases in which I had to escalate to our account manager
