Description

Previously, auto expanding archive mailbox expansion was supported only up to 1.5 TB, after which mailboxes would become inoperative. Archive mailboxes can now automatically expand beyond the 1.5 TB limit, ensuring uninterrupted retention and enabling scalable archive growth as storage thresholds are reached. This capability to expand archive beyond 1.5 TB will be available to customers with eligible E5 licenses.
