Last week I have posted the problem with Unity - Exchange permission. When Exchange subscriber send voice message, the system promt: "the system is not available...". You guys told me to check the permission and run PW. I changed AvCsMgr service user and run PW for this user for mailbox, it works!
Now, subscriber send voice message, system promt: "your message has been sent", but the destination subscriber doesnt receive anything. No voice message alert or MWI, I try to check the mailbox but no new message. So what is the problem? Could you please tell me how to resolve this, thank you very much.
