<p>Newly installed Exchange 2003 server in our network, The client computers with windows 7 and MS outlook 2010. We came across a problem with MS outlook 2010 throwing Errors 0x8004011C, 0×8004011 on clicking send and receive button.
Outlook kept updating, showing connected to exchange server and were receiving the emails. Microsoft found that there is a bug in exchange 2013.
Work around to fix this Errors 0x8004011C, 0×8004011 is that need to change the authentication method to Auto discover and also in outlook.
On the Exchange server, open power shell and run this command.
Set-AutodiscoverVirtualDirectory -Identity ‘autodiscover(default Web Site)’ -WindowsAuthentication $true -BasicAuthentication $true
Set-OutlookAnywhere -Identity:YourExchange2013CASServerrpc (Default Web Site) -IISAuthenticationMethods Basic,NTLM
Restart the Outlook 2010 and click on send and receive button.
