Method 1: Disable SCP lookupImportant
Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.
- Open Registry Editor.
- Locate and then select the following registry subkey:HKEY_CURRENT_USER\Software\Microsoft\Office\x.0\Outlook\AutoDiscoverNote The x.0 placeholder corresponds to the version of Outlook (16.0 = Outlook 2016, 15.0 = Outlook 2013).
- On the Edit menu, point to New, and then click DWORD Value.
- Type ExcludeScpLookup, and then press Enter.
- Right-click the ExcludeScpLookup value that you created, click Modify, type 1 in the Value data box, and then click OK.
Method 2: Remove the Exchange SCP objectsWarning This procedure requires Active Directory Service Interfaces Editor (ADSI Edit). Using ADSI Edit incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems that result from the incorrect use of ADSI Edit can be resolved. Use ADSI Edit at your own risk.
- Open ADSI Edit.
- Right-click ADSI Edit, click Connect to, click Configuration in the Select a well known Naming Context box, and then click OK.
- Locate the following container: CN=Servers,CN=Exchange Administrative Group,CN=Administrative Groups,CN=<Exchange Org>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=<Domain>,DC=<com>
- Expand the server, expand Protocols, and then expand Autodiscover.
- Right-click the SCP object (the object is equal to CN=<ServerName>), and then click Delete.
- Click Yes to confirm the deletion.
- Repeat steps 4–6 for each additional server that's listed in the container in step 3.
