Hi all, I’ve recently had the chance (as many of you know) of giving two sessions at the first edition of the European Office365 Connect event (Haarlem, Netherlands) which I really enjoyed a lot, not just for the great speakers that it had (Seb Mathews, Dan Holme, Marc Reguera, Jasper Oosterveld, Albert-Jan Schot, Bram de Jager, Danny Burlage, Dejan Foro, Patrick Lamber, Rolly Perreaux, etc…) but also for the great attention received by the organizers and how everything was mounted (a 5 star event).

Below you can find a brief description of the sessions I gave and the slides/resources used on each one of them. Enjoy them:

Managing Office 365 with PowerShell

Office 365, like many Microsoft products, can be managed via PowerShell and in this session we will take a look at some of the common commands you can use to become a well-rounded Office 365 Administrator. If you are new to PowerShell this session will cover some of the basics as well as covering the more “advanced” commands you can use.

Building a hybrid configuration with Exchange 2013

Everybody talks about Office 365, not every organization is ready to go «full in». Enter the cloud at your own term by going hybrid, is a quote often used. But is it really that easy or are you getting in for a rollercoaster without knowing it. In this session we’ll cover how to prepare for a Exchange Online hybrid, we’ll lead you through all the requirements and actions for a working Hybrid scenario. After this session you’ll be able to make a well founded decision about hybrid and how to make it a success story.

Buenas!, hoy tuve la oportunidad de resolver una incidencia muy común de un Exchange Server 2013 de un cliente con un entorno de DNS algo restrictivo. El problema radica en que los mensajes que se envían a través de OWA (o en la bandeja de salida de Outlook) se quedan atascados en la carpeta de borradores y no terminan de enviarse.

Bueno, por supuesto que es de Exchange Server 2013 de lo que estamos hablando, pero… sabes que version de Exchange correo en Exchange Online??? Exacto!, Exchange Server 2013 :), aso que puede ocurrir de igual forma si estas en Exchange Online con la diferencia que la solucion esta en lo que no puedes ver y el equipo de soporte de Microsoft seran los unicos capaces de resolver este fallo.

Pero la historia cambia cuando tenemos un entorno On-Premises o Hibrido :)

La principal razon de porque los mensajes se quedan atascados en la bandeja de salida es porque los enlaces de DNS estan configurados de maña manera y Exchange tiene que saber donde entregar el mensaje.

Así que, quizás te gustaría echar un vistazo en la EAC – Servidores – Doble Click en el servidor CAS que tiene el problema – Búsquedas de DNS, y establecer las direcciones de DNS tanto para correos internos como externos.

Después de eso, los usuarios deberían ser capaces de enviar mensajes normalmente.

Hi all, today I had the opportunity to solve one of my customers Exchange Server 2013 issues that is very common in restrictive DNS environments. The issue was about sent messages being stuck at the drafts folder and Exchange Server wasn´t able to send them out when using OWA (or Outbox with Outlook).

Well, of course it´s Exchange Server 2013 we´re talking about, but… do you know what Exchange Online is running on??? Yep!, Exchange Server 2013 :), so it can happen also if you´re on Exchange Online with the difference that the solution resides on what you can´t see and Microsoft Support Team will be the only ones able to solve it on this case.

But the story is different when you have an On-Prem or Hybrid environment :)

The main reason of why the outgoing messages are being stuck at the drafts folder is because of DNS bindings that may be incorrectly configured, and Exchange has to know where the message has to be given.

So, you would like to take a look at the EAC – Servers – Double Click to the CAS server that has the issue – DNS Lookups, and configure the DNS servers for both, Internal and external mails.

After that your users should be able to send messages normally.
