We are always getting this alert every time I open Outlook 2013. We are using Exchange 2010. Could you please help us on this?

Well it's warning you because of issues with the certificate, so you fix that. Or you can suppress the warnings following the instructions here: http://support.microsoft.com/kb/2783881

Hi rueltags,

1. please check the URLs you configured. It seems that one of get-exchangeserver , get-autodiscovervirtualdirectory, get-webservicesvirtualdirectory does not use hostnames like mail.khadamat.ae 

  -->that caused the second X the name of the security certificate is invalid ...

2. your certificate isssued by a CA that is not listed in your clients  list of trusted issuers. please check if you deployed the corresponding issuers CA to a trusted CA store. Use "View certificate" and choose the certificatin path, there you will find which  certificates  need to be installed

--> That caused the first X "... issued by a company you have not chosen to trust ..."

If you need further assistence, please also post the output of  get-exchangeserver | fl, get-autodiscovervirtualdirectory | fl, get-webservicesvirtualdirectory | fl

see https://technet.microsoft.com/en-us/library/dd876959%28v=exchg.141%29.aspx for step-by-step instructions.

Hi rueltags,

Thank you for your question.

Did outlook 2010 get this alert?

Did outlook get alert all the time when Exchange 2010 was installed?

If new Exchange 2010, we could refer to the following link to rebuild Exchange certificate for Exchange and make sure the same SAN name:

If the alert occurred recently, are there any updates? if not, we could refer to Vasils advice to suppress the auto discover mismatch warning.

Notice: after we deploy the certificate, we must import certificate to client  owing to the first error information which is in security alert window.

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim
