Much improved

With the update to Horcrux that was released on Sept. 9, I’ve had a successful backup every day. The developer claims to have reduced memory usage by 90%, and that seems to be true. My computer no longer crawls when a backup is happening. At this point, I would say that Horcrux works well and, if it doesn’t, the developer is open and responsive to feedback.

Useless when it crashes

Leaves you in the dust when it crashes. And it crashes a lot. Tried it on multiple systems. When ever it comes across an email it doesn't like it just dies. You're totally left hanging in the middle of a migration and you don't know where it died. I'm sure the developer "has never experienced this.." blah blah blah. But in this day and age, I just need something that works. I don't need to beta test their stuff for them. In the future try your product on some REAL mail migrations, not just the small stuff in your lab. Don't use me as your guinea pig. I don't appreciate it, especially when I paid a decent fee for this to just work.

Great little application; very good support

I’ve used this application to backup IMAP, Exchange and Gmail accounts for several years.

It works very well, and allows easy access to the archives it creates.

When I have had problems, the developer has been very responsive - asking daily questions about my setup and suggesting ways to fix the problems I was having.

Different mailboxes have different problems, and several times the app has been updated to address crashes or hangups that I have experienced.

This is an awesome application, and the support is excellent.
