One of the issues you will run into when migrating from an on premises Exchange 2010 server on SBS 2011 is that Outlook will not autodiscover the correct Office 365 server settings. Fortunately this can be easily solved with a few simple PowerShell commands.
- Open an Exchange Management Shell as an administrator. (Elevated PowerShell)
- Use the following command to discover the Identity name of your Autodiscover Virtual Directory. Either note or copy the values in the Identity field.
Get-AutodiscoverVirtualDirectory | fl Name, Server, InternalUrl, Identity
- Use the following command to remove the AutoDiscover Virtual Directory. Be sure to replace the text inside the quotes with the value in the Identity field above.
Remove-AutodiscoverVirtualDirectory –Identity “Insert identity value here”
- You will have to confirm the removal by hitting Y for yes when prompted. You can double check to see if this worked properly by rerunning the command in step 2. You should get a blank result if successful.
That should be it. Your Outlook clients should connect successfully to the Office 365 service.
