A connection test in the Conferencing Add-in for Office Outlook is unsuccessful where only an A record is available but no SRV record is available in an Office Communications Server environment
Consider the following scenario:
- In a Microsoft Office Communications Server (OCS) environment, only an A record for the OCS front-end server is available. No Service Location (SRV) record for automatic client logon is available.
- You try to use the Test Connection function in the Conferencing Add-in for Office Outlook, which uses automatic discovery.
In this scenario, the connection test is unsuccessful. Therefore, you cannot schedule conference calls in the Conference Add-in for Office Outlook.
This issue occurs because the result of a DNS query against an A record does not match the corresponding settings on the OCS front-end server.
