Hello,

We have brand new Exchange 2013 installation, one domain, one server.

OWA and mobile devices work fine and the Outlook testconnectivity test gets past the DNS, Firewall, certificate tests successfully 

Outlook Account setup:

Add an email account to Outlook 2007 while at home but internet connected

Set up a new profile normally,

Search for Server Settings stalls,

Popup reports : this action cannot be completed.  The connection to Microsoft Exchange is unavailable.  Outlook must be online or connected to complete this action

A Microsoft Exchange pops up that shows

Microsoft Exchange Server: 

e82062d9-04a6-4bf8-acbe-dbc01cf81eb7@domain.com

Mailbox:

=SMTP:username@domain.com

Hi,

Please check whether there is any related Exchange service is not started in Exchange 2013. Please restart the following service:
Microsoft Exchange RPC Client Access
Microsoft Exchange Service Host
Microsoft Exchange Mailbox Assistants
Microsoft Exchange Mailbox Replication

Also check whether the mailbox can be available in OWA. In Exchange server, please check whether there is any related error in Event Viewer.

Hi,

Any updates?

Regards,

We got the issue resolved by using the Exchange shell set-outlookanywhere cmdlet.

ExternalClientAuthenticationMethod : Negotiate

InternalClientAuthenticationMethod : Ntlm

IISAuthenticationMethods           : {Basic, Ntlm, Negotiate}

Once these were in place, Outlook Anywhere worked normally.

Thanks!
