The evaluation license is a free and fully-functional license that can be used for evaluation and testing purposes only.
Within a month before the expiration date, you will be receiving a notification message stating that your license is about to be expired. During this period, the program functionality will not be limited by any means. After your license has expired, processing of all mailboxes will be stopped.
The restore abilities will continue to function regardless of whether your license has expired or not.
Processing of mailboxes that exceed the allowed license count will not be possible.
