If you can’t remove them because of some error use the metebase explorer (google) and follow these steps:

2. Run it as Administrator
3. Browse to Wssv –> 1 –> Root –> Autodiscover
4. Dont delete it first, rename it to whatever…
5. Check Metabase Explorer and IIS Management to make sure your new Autodiscover Application is listed.
6. Delete old renamed directory in Metabase explorer…
Create the EWS and Autodiscover again
New-AutoDiscoverVirtualDirectory -websitename “Default Web Site” -WindowsAuthentication $true -DigestAuthentication $false -Internalurl “https://server.domain.local/EWS/Exchange.asmx” -ExternalUrl “https://server.domain.local/EWS/Exchange.asmx“
Give an IIS reset.
