Hi,

I have configured Exchange Hybrid via edge transport servers and I have an issue where the Office 365 Outbound connector is not syncing to the edge. When I run Test-EdgeSynchronization -FullCompareMode I get the result below:

LeaseType : Option
FailureDetail :
LeaseExpiryUtc : 17/08/2020 04:34:25 PM
LastSynchronizedUtc : 17/08/2020 04:04:25 PM
TransportServerStatus : Synchronized
TransportConfigStatus : Synchronized
AcceptedDomainStatus : Synchronized
RemoteDomainStatus : NotSynchronized
SendConnectorStatus : NotSynchronized
MessageClassificationStatus : Synchronized
RecipientStatus : Synchronized
CredentialRecords : Number of credentials 21
CookieRecords : Number of cookies 3

For some reason the SendConnectors and RemoteDomains are marked as "NotSynchronized".

I have no idea why this is occuring and there is no Microsoft documentation I can find to explain why this is occuring.

Mike.

    What's the version of your Exchange server? After you configuring the hybrid the issue occured or you made any changes may lead to the issue?

    Get-ExchangeServer | fl Name, version

    Make sure your certificate is configured properly: Update Edge Server Certificate in a Hybrid Exchange Environment

    Have you tried using Start-EdgeSynchronization to immediately start synchronization of configuration data from Active Directory to the subscribed Edge Transport servers?

    You could also recreate the edge subscription which would be possible to solve the problem.

    The official document also notes that: If you need to delete and recreate an Edge subscription that's used to communicate between your on-premises organization and Exchange Online, make sure to run the Hybrid Configuration wizard again. Recreating an Edge subscription removes configuration changes that are needed for your on-premises organization to talk to Exchange Online. Re-running the Hybrid Configuration wizard applies those changes again.

    Please also check the event log on the edge server to get more information related to the issue.
