Hi Friends, before the Exchange Migration i wanted to set Outlook Anywhere to Ntlm on the SBS.
I also completed the prepare schema for exchange 2016 several hours before the change to ntlm.
Original State:
Get-OutlookAnywhere | Select-Object -Property SSLOfflading,ExternalHostname,InternalHostName,ExternalClientAuthentificationMethod,InternalClientAuthentificationMethod,IISAuthentificationMethods
SSLOffloading:False
ExternalHostName : mail.domain.com
InternalHostName:
ClientAuthentificationMethod:Basic
IIS AuthentificationMethods: {Basic)
After setting this command: Set-OutlookAnywhere -Identity 'SERVERNAME\Rpc (Default Web Site)' -SSLOffloading $true -ClientAuthenticationMethod NTLM -IISAuthenticationMethods Basic,NTLM
Nothing works anymore. Outlook can't connect.Creating a new profile is possible, but than again it won't connect.
Also can't export users to pst anymore or migrate to another database.
But i can still create New Mailboxes and the Database is still there!
Owa Error:MapiExceptionCallFailed: Unable to make connection to the server.(hr=0x80004005, ec=5)

EventMgr:Ms Mailbox Replication isn't working, with the same owa error
Setting Back to SSL False and ClientAuthenticationMethod to Basic
Get-OutlookAnywhere | fl server,name,*hostname,ssl*,*auth*
Server: ServerName
Name : Rpc (Default Web Site)
ExternalHostname : mail.domain.com
SSLOffloading : False
ClientAuthentificationMethod: Basic
IISAuthenticationMethods : {Basic}
I noticed that in iis under RPC-->Authentification , the Windows Authentification is enabled with the options Ntlm and Negotiate.
It wasn't enabled before the changes.
I'm a little bit lost, something is blocking the access.The Remote MS Analyzer is still connecting.
Any ideas?HELP :-)
