I am currently using SuSE Open Exchange Server in my organization, but Novell is dumping it and I'm not really sure I want to migrate to the new company and stay with the product.
I really like what I see with your product and I like the direction you are headed. There are a few things that will prevent me from migrating to your product. I would like to know if the following are in development or planned for development for your web interface.
First is the scheduling of resources such as conference rooms.
Second is the use of groups in address books or at least a drag and drop of contacts from one address book to another.
Third is being able to select multiple files for attachments or a drag and drop solution of files into email.
Finally, it would be nice to have the ability to export or archive an email from the web interface.
All of these items are very important to the way we do business and if you are adding or plan to add these items, your product would stand above the rest. Knowing the above would also make my decision about migrating to your product much easier.
