EventID 3018 - Exchange can't connect to https://o15.officeredir.microsoft. com

Hi

I've just installed Exchange 2013 at a customer.

The servers are logging Event ID 3018 every hour. We know why and the network group have let the servers bypass the proxy now so the alarm is gone.

BUT the customer wants to know why Exchange needs to contact this URL every hour. Is it needed?

Any idea? :-)

Hi Steen,

No, it is not needed.

You can prevent it by having Exchange make this call through a proxy server, use the Set-ExchangeServer cmdlet to achieve this:

Set-ExchangeServer Server01 -InternetWebProxy http://x.x.x.x:80

Hi Niko

I did try that - it doesn't work at all. 

Then I just get this error every hour.

Scenario[ServiceHealth]: GetConfig. CorrelationId: b1a928a4-ef6a-4b14-b655-c11dd69a5685. The request failed. Mailbox:  Url: https://o15.officeredir.microsoft.com/r/rlidMktplcWSConfig15?CV=15.0.1076.9&Client=WAC_Outlook&corr=b1a928a4-ef6a-4b14-b655-c11dd69a5685 Exception: System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 168.62.204.209:443

I know the blogpost you link to, but see the error

failed because connected host has failed to respond 23.97.152.190:443

Mine is refused by MS server?
