Exchange 2013 and Office 365 using LEA proxy, cant complete Hybrid Config Wizard
I am struggling to complete the Hybrid Config Wizard, it goes through; Connecting to tenant, Checking tenant pre-requisites, Configuring organization relations but then stops with this:
Updating hybrid configuration failed with error 'Subtask NeedsConfiguration execution failed: Configure Organization Relationship Exchange was unable to communicate with the autodiscover endpoint for your Office 365 tenant. This is typically an outbound http access configuration issue. If you are using a proxy server for outbound communication, verify that Exchange is configured to use it via the “Get-ExchangeServer –InternetWebProxy” cmdlet. Use the “Set-ExchangeServer –InternetWebProxy <name of your proxy server>” cmdlet to configure if needed. at Microsoft.Exchange.Management.Hybrid.OrganizationR elationshipTask.get_OnpremisesFederationInfo() at Microsoft.Exchange.Management.Hybrid.OrganizationR elationshipTask.NeedsConfiguration(ITaskContext taskContext) at Microsoft.Exchange.Management.Hybrid.Engine.Execut eSubStep(String subStepName, ITaskContext taskContext, ITask task, Func`3 substep, Func`4 createException, Boolean throwOnFalse) '.
I have tried adding our LEA provided proxy settings in NETSH but it still stops at this point.
Could it be a port issue like 997 being blocked?
Currently our onsite Exchange 2013 server is running fine in all respects. How did you guys configure yours if you're behing the LEA firewall and using their proxy? Or is this a red-herring and I shouldn't read too much into the MS error?
I know i'm a bit light on surrounding details but I think it MAY not be relevant if someone had the same isssue...
Any advice would be most gratefully received.
