Hello Exchange Experts,
I have an issue with the coexistence of Exchange 2007 and 2013 during the migration. When I move a mailbox from 2007 to 2013, the Outlook profile updates itself automatically with the new server information and HTTP connection settings, but when Outlook opens it hangs for about 1 minute and then claims, that MS Exchang is not available.
The Clients are using Outlook 2007 with newest patch level.
I configured OutlookAnywhere like this:
E2k7
====
SSLOffloading : False
ExternalHostname : mail.contoso.com
ClientAuthenticationMethod : Ntlm
IISAuthenticationMethods : {Ntlm}
E2k13
=====
SSLOffloading : True
ExternalHostname :
InternalHostname : mail.contoso.com
ExternalClientAuthenticationMethod : Ntlm
InternalClientAuthenticationMethod : Ntlm
IISAuthenticationMethods : {Ntlm}
ExternalClientsRequireSsl : False
InternalClientsRequireSsl : False
Does anyone have a suggestion for that issue?
Thank you very much and best regards,
Sebastian
