Look for an option called “Enable RPC encryption” and double-click it.Next, navigate to User configuration ->administrative templates ->classic administrative templates (adm) ->Microsoft office outlook 2007> Tools.The best way to do it is press the Windows key and the 'R' key and type out 'gpedit.msc' in it. Download the latest version of Outlk12.adm group policy template and add it to your domain controller.To enable RPC encryption in Outlook 2007, follow these steps:

By default, the RPC encryption is disabled in Exchange Server 2010 service pack 1, so you’ll have to manually enable it.Īlso, you’ll get this message if you’ve disabled the “encrypt data between Microsoft office outlook and Microsoft exchange” option in your profile settings. You’ll get this error message when your RPC encryption is not enabled. Here are some of the things you can do to fix “the connection to Microsoft exchange is unavailable” error. However, if you’re using Outlook 2007 or 2010, the process is going to be a little longer. Since Office 365 is a cloud-based app, it’s easy to fix this error. Otherwise, you’ll have to send a request to the system admin. You can do it by yourself if you’re the admin. Finally, when you’re prompted for the login credentials, use the original Office 365 email address, and it should work.Īn easier way than the previous option is to change the username or password in either Office 365 or your third-party provider, so that the login credentials are unique.Use the new alias instead of your email address to set up your Outlook.Select the SMTP server and add a new alias to your domain.Next, choose email address and click on the '+' sign.

Navigate to recipients -> mailboxes and click on your mailbox.

Create a new aliasĪ common way to solve this problem is to create a new alias in Office 365 and use this alias to set up your Outlook. It happens typically when you use the same email address and password for your Office 365 account and for your third-party provider’s login. If you’re an Office 365 user and you get this message, the most likely cause is a conflict in your username and password. When you see this error message, simply try one of the below options and, hopefully, one of these should fix it for you. If you’re like me, you’ll probably go through the different possibilities in your mind and try to zone in on the most likely cause of the problem. Well, “connection to Microsoft exchange is unavailable” is one such cryptic message that doesn’t tell you much about why there is no connection. Isn’t it always annoying when we get an error? And it’s especially galling when the error is a cryptic one that doesn’t tell us the cause of the problem.
