Hybrid Configuration - Exchange 2013 and Office 365

[taj_bhatti_2983]

Hello All,

I'm setting up Hybrid Configuration between Exchange 2013 and Office 365, I've F5 (LTM-APM) -BIG IP V11.5.1 Hf7) doing necessary load balancing for my four CAS servers however when I run my hybrid wizard I'm getting following errors...

Is there any specific exclusion I need to put on F5 for below error ?

I've enabled mrsproxy on all CAS servers - and have necessary authentication on IIS setting for

InternalAuthenticationMethods : {Ntlm, WindowsIntegrated, WSSecurity, OAuth}

ExternalAuthenticationMethods : { Ntlm, WindowsIntegrated, WSSecurity, OAuth}

Any help will be appreciated ...

do you see the request show up in APM logs? where does it fail on?

did you configure it yourself from the ground or used an iApp.

This is pretty old, but maybe useful for others browsing to check this out: https://social.technet.microsoft.com/Forums/en-US/25b0b80f-7578-4a85-9e99-c51317ec390a/exchange-2016...

I had a VERY similar sort of error (don't think mine mentioned basic auth, else identical. Gist is, make sure your proxy's enabled and do an iisreset. Here's the forum's pith:

get-webservicesvirtualdirectory | fl Server,MRS*, if not enabled use the cmdlet below to enable.

get-webservicesvirtualdirectory |set-webservicesvirtualdirectory -mrsproxyenabled $true

Run an IIS reset..
