Quite often this problem occurs to messaging administrators when deploying Exchange 2013 Edge Transport server role.
After creating a new EdgeSubscription you call for results with Start-EdgeSynchronization and get the following response:
[PS] C:\Start-EdgeSynchronization -Server mbx.domain.local -TargetServer edge.domain.com -ForceFullSync RunspaceId : 578a8a8c-002b-4bf4-86ff-f78c285d2944 Result : CouldNotConnect Type : Configuration Name : Edge FailureDetails : The LDAP server is unavailable.

First check firewall rules to and fro EdgeTransport and
telnet servername 25
Test-NetConnection servername -Port 25
If everything seems to be all right – there still one thing might left overlooked –
Your Exchange Server 2013 must be supplied with a product key to run EdgeSync successfully!
Many seem to forget or think to postpone installing the license key to EdgeTransport. However, unlike previous versions, Exchange 2013 EdgeTransport role fails to interact with rest of services in such case.
Get-ExchangeServer servername | fl Edition,IsExchangeTrialEdition,IsExpiredExchangeTrialEdition
If you find your server is unlicensed yet –
Set-ExchangeServer servername -ProductKey XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
Since EdgeTransport does not run any user databases – there is no need to restart anything here. You just need to recreate your EdgeSubscription once again. This issue must no longer be a problem for you.
