For most Aid4Mail licenses, activation is carried out online and requires an Internet connection. However for Aid4Mail eDiscovery licenses, and some Aid4Mail Console licenses, an offline activation option is available.
Note that when Aid4Mail is activated online, it will also check the license status at least once a month, again requiring an internet connection. Don’t worry if you don’t use Aid4Mail that often, or if you don’t have a regular internet connection. In these cases, Aid4Mail will simply revert to trial mode until you can re-activate online.
