Help Users cannot connect to new exchnage Internally

By default Exchange 2013 autodiscover needs UCC, you also can use SAN Wildcard certificate but it depends based on the multiple domains. Recommended is public UCC certificate. You can go with any UCC certificate providers like digicert, godaddy, etc.,. If the autodiscover works well, then you wont be facing issue with the client communication with Exchange 2013.

To identify the connectivity and certificate issues : https://testconnectivity.microsoft.com/ run this and post the error you see.

Ok so just to clarify

my exchange server is called exchange which is on a domain so exchange.domain-uk.com

if I purchase a wildcard cert for domain-uk.com, internal users will be able to connect? or do I still need to creat an A record pointing to the server.

is there not a quick workaround just to get these guys working?

What I posted above is are the steps required. I would recommend reviewing them but you have the certificate portion done which is great. If you do not setup Autodiscover correctly this error will show.

I would also check to make sure that IIS is assigned to your certificate.

get-ExchangeCertificate |fl

Ok I purchased a wild card cert from go daddy

I clicked complete in the ECP console browsed to the .crt location but when I try to install I get the following


Sorry but I am pretty new to Exchange and have users screaming at me at the moment any more help much appreciated

Run the following in Exchange management shell:

Get-ExchangeCertificate -Thumbprint 414CF234B784F320036BEFCF0EE4A26DA9C715C6 | FL

Select allOpen in new window

Post the results here for review into a text file (its easier for us to view).

that errors I have attached

Cert.txt

ive seen this before :)

Try repairing the certificate store:

certutil -repairstore my "YourSerialNumber"

Select allOpen in new window

That serial number should be the thumbprint. Once you are done rerun the import request and try the command I gave you above. Also try "Get-ExchangeCertificate | FL" and post the output.

**edit**

Much better instructions: https://support.comodo.com/index.php?/Knowledgebase/Article/View/624/0/privatekeymissing-when-running-enable-exchangecertificate

I ran into the SAME EXACT issue when I did this on my first Exchange 2013 deployment. I think something with Exchange / Server 2012 is funky.

Arrggggg

I managed to install the Cert however users were still getting certificate issue, now I can no longer access EAC I logon in and just get a white page, I have read this can be cause by certs.

Please helpp

Run IISRESET /NOFORCE or restart the Exchange servers..

I have restarted twice but still no luck

I found this but how do I know what cert to delete?

http://www.techieshelp.com/exchange-2013-eac-ecp-blank-screen/

these are my certs but im not sure which one to delete

On the blank ECP screen (in the browser) look at the certificate. That is most likely the one that needs to go.

ok I have deleted the cert now I cannot even log into ecp, meaning I get page cannot be displayed not even a login box anymore
