About Mailbox Stores Consider the following points to understand the importance of mailbox stores in Unity Connection: • During installation, Unity Connection automatically creates: • A directory database to store system configuration information, such as user data and templates. • A mailbox store database to store information, such as the sender of each message and the location of the .wav file associated with a particular voice message. • An operating system directory to store voice message .wav files. • A Unity Connection server or cluster supports up to 20,000 users. You need to create a separate mailbox store for every 5000 users. Creating additional mailbox stores allow you to backup selected mailboxes and ensure that backup gets completed during non-business hours. • You can modify the default 15 GB size of the Unity Connection mailbox stores depending on your requirements. The maximum mailbox size recommended by Unity Connection is 30 GB. • An administrator with the required permissions can create up to four additional mailbox stores. Each additional mailbox store includes a separate mailbox store database and a separate operating system directory. • The directory information of all the users in a Unity Connection server or cluster remain in one directory database created during Unity Connection installation.
