Hi I want to know how can i read my own spark history and if i was the admin then how to read all others
You can access a history with a specific contact by opening a chat window and clicking on a history button. Spark saves history locally in C:\Users\username\AppData\Roaming\Spark\user\username@servername\transcripts so admin with OS access can reach it and read the history files. If Openfire is used as a server and it has Monitoring Service installed, admin can access logged chats in Admin Console.
