Problem with default OTRS Appliance 4.0.3

[xtheb]

Hi all,

I installed OTRS Appliance 4.0.3 on a virtual machine.

I wanted to test a conversion of mail into a ticket so as the "Superuser", I went to Admin / PostMaster Mail Accounts.
I added a new mail account using the following settings :
Type : IMAPTLS
Host : outlook.office365.com
IMAP Folder : INBOX
Trusted : No
Dispatching : Dispatching by email To: field
Validity : valid

As testing with Fetch mail in the RUN NOW! column I got the following error :

Error Message: IMAPTLS: Can't connect to outlook.office365.com: Unable to connect to outlook.of[..]

Error Details
Backend ERROR: OTRS-CGI-35 Perl: 5.10.1 OS: linux Time: Fri Jan 16 16:17:38 2015 Message: IMAPTLS: Can't connect to outlook.office365.com: Unable to connect to outlook.office365.com: IO::Socket::INET: Bad hostname 'outlook.office365.com' RemoteAddress: 192.168.1.42 RequestURI: /otrs/index.pl?Action=AdminMailAccount;Subaction=Run;ID=1;ChallengeToken=xtSmkjcUrawEMjEf5T1ggZtpT5X8Q9g8; Traceback (1635): Module: Kernel::System::MailAccount::IMAPTLS::_Fetch Line: 138 Module: Kernel::System::MailAccount::IMAPTLS::Fetch Line: 81 Module: Kernel::System::MailAccount::MailAccountFetch Line: 441 Module: Kernel::Modules::AdminMailAccount::Run Line: 63 Module: Kernel::System::Web::InterfaceAgent::Run Line: 986 Module: ModPerl::ROOT::ModPerl::Registry::opt_otrs_bin_cgi_2dbin_index_2epl::handler Line: 41 Module: (eval) (v1.99) Line: 204 Module: ModPerl::RegistryCooker::run (v1.99) Line: 204 Module: ModPerl::RegistryCooker::default_handler (v1.99) Line: 170 Module: ModPerl::Registry::handler (v1.99) Line: 31

I tried to change parameters Type and Trusted but it didn't changed anything to my problem.
I haven't edited any file and the network is opened - no firewall.
The problem does not come from outlook, it works normally on my PC.

Did I missed something or does it come from OTRS, Debian or the VM?

Thanks in advance for your answers.
