Everyone from every department uses Office 365 and we delete thousands of emails in a month or so that are auto-triggered in our production environment which we don't find relevant at that time but later that email saves our project in some folder. We delete all emails to make space for new emails to come in, and in that process. If we lose those emails then we simply use MailMeter to see the deleted email with a request and use advance search and download or tag that email.
Of the few times I've dealt with support, I felt like the people who were on the other end couldn't help me. Latest instance was with resolving a license renewal issue, they had to connect me to someone in Ireland and were on a tight schedule to help me during their shift. Come to find that I could not renew a license because their license server was down. In all it wasn't a good support experience, however unfortunately par for the course.
Probably an unfair comparison, but Mimecast has some interesting features that MailMeter does not. First, Mimecast is cloud, MailMeter is on-premise. Mimecast has all the same eDiscovery features that MailMeter has, however is also able to offer seamless archive stubbing into Outlook. Since you don't have to suck up resources on your local network, you easily save money spent on disk/compute resources.
This product has done a bang up job in providing quick access to historical email content. The amount of time saved, including instant verification of email transactions, make this product worth the yearly license.
As a result of hosting our mail archive onsite, we have had to spend large amounts of our total pool on disk space, cutting down on overall ROI.
MailMeter does not require hefty Virtual Machine resources, which allows us to allocate resources towards other servers.
