An Exchange Unified Messaging (EUM) voice mail message is not delivered to the appropriate mailbox in Microsoft Office 365 dedicated or ITAR. Instead, the caller hears dead air or a fast busy signal.
This issue occurs because the mailbox is enabled incorrectly for EUM by using appropriate proxy addresses in the source and managed environment when you use on-premises Microsoft Lync voice.
When Lync voice is on premises, two proxy addresses on the managed and source object are required to enable the mailbox for EUM. When you enable the mailbox for EUM, the proxy addresses are added to the managed mailbox object automatically. The proxy addresses must be added to the source object manually. The proxy addresses may resemble the following:
eum: email@example.com;phone-context=E14 EUM.contoso.com
eum: 92184;phone-context=E14 EUM.contoso.comTo confirm that the mailbox is enabled for EUM and that the mailbox has the correct proxy addresses, follow these steps:
- Check whether the mailbox is EUM enabled together with the correct telephone number. (This process automatically adds the EUM proxy addresses to the managed object.) To do this, use the following Windows PowerShell cmdlet: Get-UMmailbox <user's SMTP>
- Add the two proxy addresses to the source object. The added proxy addresses make sure that the Lync voice on-premises servers can route unanswered calls to EUM.
