Sharing a page I came across recently — Mimecast Support Services from Zazz — for anyone looking into mimecast support services.
Maximize your email protection with Mimecast support services from Zazz. Expert configuration, monitoring, and support for secure business email.
Two things stood out. The information is organised in a way that actually helps you find what you need, and it's written in plain language without unnecessary jargon. That's rarer than it should be for mimecast support services material.
I'm saving this resource as a reference and sharing it here in case it's useful to anyone else researching the same topic.
