- UnityMsgStoreSvc mailbox resides on EXC-03
- In 03-to-10 Connector: EXC-01 was listed as the only server to be able to send emails & EXC-02 is the only Remote Bridgehead
1. Emails queued in UnityMsgStoreSvc mailbox: the "unity_UNITY" account password must have expired. Changed the account to never expire, then emails start to empty from the mailbox.
2. However, the emails now stuck in the Connector queues on EXC-01, and unable to connect to EXC-02. Reboot EXC-02 to resolve this.
