Hello Before We were able to use outlook 2010 to connect exchange server 2010 using outlook anywhere(rpc over https). All the laptops are part of the domain. No changes on the server except updates. Now we are not able to connect to exchange server. It comes with " server is not aviable". I checked the connection status, it is trying connect through TCP/IP not https. But my home laptop is not part of the domain, I tested my home laptop with outlook 2007, it works. My home laptop is connecting through rpc over https.. Now i do not understand it it a network issue or outlook 2010. Please help me Regards Suresh

Hi Suresh, 1- Did you compare the Exchange Proxy Settings of the two machines? Is there anything different? 2- also did you check the authentication method? ecsword

Suresh, There may be various reasons for this. Most probably, the connectivity failure with the Exchange server to specific ports. Check the connectivity to port 443 through telnet to the url. Also check firewall, proxy etc. to ensure that they are approaching in friendly way to outlookRegards from ExchangeOnline

Hello, Tod. Today i removed my work laptop from domain and tested for outlook anywhere it works. The same laptop works when it is not part of the domain. But it is not working when it is domain joined laptop. Now i do not know what to do. Thanks, Suresh

Hello Can you check autodiscover is working from domain joined machines, check the outlook Test Email autoconfiguration By default outlook is configured outlook anywhere if it is discovered the mailbox automatically. Thanks Mouzzam Hussain Visit to my Blog mouzzamh.wordpress.com

Hello Mohammed, Autodiscover works for domain computers using this took https://www.testexchangeconnectivity.com/ Test Email Configuration is not working for domain laptops but it works for non domain laptops Thanks, Suresh

Hello Man PhiliP I tested non domain laptops, it connects. Not with the domain laptopns I thing our problems is domain laptops are not connecting for outlook anywhere

I would surmise that your internal SCP record for Autodiscover is configured incorrectly, then. Run: Get-ClientAccessServer | FL Name,AutodiscoverServiceInternalUri and correct as necessary.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hi, Agree with Ed. It' be good to check the InternalUri also What is the error that you are getting with Test Email Configuration? ecsword

hi Suresh, Is it server side updates or outlook side updates. I suggest try to remove those updates first & see it comes back to normal. please share the update list you pushed to client/server. Additionally check if service connection point entries are in place for you CAS server.DV MCTS,Exchange 2010
