Our email environment is complicated and we use GroupWise as a data sync server. We have around 700 users and approximately 10 terabytes of emails with four servers. We are customers of GroupWise, supporting our clients who need IT assistance. I'm the head of NCIS.
The solution is very flexible and has great storage capacity. If you have, for example, two terabytes of email data in a GroupWise system, it would be equivalent to five or six terabytes in another tool that would likely also require more resources. It's a huge advantage. This is a simple tool and we find it to be more secure than Exchange.
