I recommend Enterprise Vault, especially over native Exchange archiving when: 1. You have, or may need litigation holds and searches 2. There is a need to archive and set defined retention periods for Journaling 3. You have lots of duplicate large emails that you want to get deduplication of 4. You need/ want to be able to search attachment in addition to emails 5. You want or need Litigation searches or archive retention to be handled by a team separate from your Email team
If you are looking for an onsite solution, MailMeter does the job. Like any program, you will have problems on occasion, however the product is fairly stable. In my opinion, mail archiving is a service that's more suited towards cloud-based services rather than on premise. Much like a spam filter that runs on a Windows server, this product feels like it's from a bygone era.
EV FSA had 2 stubbing options. We ended up using the IE shortcut as the stub replacement on the file system. In the DFS environment using DFSR the IE shortcuts allowed us to quickly and easily archive the data while allowing users to still access their data via the web or stub format. We were also able to exclude certain folders from archiving like the dfsrprivate folder. The newer versions of EV 11 and up have a better user interface to access this content from the web.
EV SharePoint implementation was pretty simple for us. Document Library archiving was pretty seamless. Archiving the different versions in sharepoint also helped further reduce total cost of storage.
EV Exchange was a good addition to our archiving portfolio. In our case we did not use the stubbing mechanism. Instead, we used the vault cache methodology. We had the option to pull down the full archive versus just the header information. The concern at the time was how quickly we could update the vault cache on the client. We ended up scaling out our EV environment to ensure the push of data could get to all our clients since we were in the middle of a notes to exchange migration. Overall I was impressed with Vault Cache and its capabilities. I also liked the ability to manage the Vault Cache and perform resets where necessary from the web browser interface.
We had EV FSA, SharePoint and Exchange as one single environment so we benefited from overall single instances of a file. Our backend systems were Netapp which we enabled deduplication for further improve storage savings. EV had a good SQL Reporting mechanism for Archiving and plenty of good canned reports.
Symantec Enterprise is one of the best in the industry. We have already deployed their product to thousands of devices in the company and it would be a huge project to go through and change to an alternative product. We have also had much luck in dealing with their customer support. They have been very pleasant to deal with and their technical support has been quite knowledgeable in fixing our issues. This leaves us with very little reason to switch to a new product. We would have to see a significant amount of cost savings to switch to an alternative that offers all the same features and modules.
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.
I haven't research any other software against Enterprise Vault. Office 365 automatically has archiving capabilities that we use in the cloud. In comparison to Office 365, I'd say Office 365 comes out on top. For one thing, we essentially don't have to manage it. It also seems to preform better. However, Enterprise Vault does very well if you have an on-premise email solution.
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.
