Lync Server 2013 Front End Service Won’t Start

Lync Server 2013 Front End Service Won’t Start and the following warning appear in the event viewer

Server startup is being delayed because fabric pool manager has not finished initial placement of users.

Currently waiting for routing group: {8EC325CB-B512-587D-9D03-E940E7CC1490}.

Number of groups potentially not yet placed: 1.

Total number of groups: 1.

Cause: This is normal during cold-start of a Pool and during server startup.

If you continue to see this message many times, it indicates that insufficient number of Front-Ends are available in the Pool.

Resolution:

During a cold-start of a large Pool it can take upto an hour for the placement process to finish as it needs to populate all the Front-End databases with data from the Backup Store. If the Pool is running and the Front-End is just started, this is normal for some time. If this repeats for a long time, ensure that all the Front-Ends configured for this Pool are up and running. If multiple Front-Ends have been recently decommissioned, run Reset-CsPoolRegistrarState -ResetType QuorumLossRecovery to enable the Pool to recover from Quorum Loss and make progress

Resolution:

Run the following CMD with ResetType FullReset intead of QuorumLossRecovery

Reset-CsPoolRegistrarState -PoolFqdn ” frondendpool name” -ResetType FullReset
