An Exchange hybrid configuration comes in various flavors. This short session helps you to understand the difference between the Exchange hybrid options and how you make the right hybrid choice for your enterprise. This is especially important when using Microsoft Teams with on-premises mailboxes.

Microsoft Teams and On-Premises Mailbox - Why? en de

Microsoft Teams works with on-premises Exchange mailboxes. But there are some caveats you might not know about, but might make you re-think your approach of staying on-premises with Exchange Server. Microsoft Teams is not the only Microsoft 365 service utilizing an Exchange mailbox as a storage container. In this session, I talk about the pros and cons of using Microsoft Teams and other Microsoft 365 workloads while keeping your users' mailbox on-premises.

Microsoft Teams und lokale Postfächer - Warum? en de

Grundsätzlich kann Microsoft Teams mit lokalen Exchange Postfächer umgehen. Jedoch gibt es einige Herausforderungen, die Sie eventuell noch nicht kennen.

Exchange Hybrid - The best approach for full migration and permanent coexistence en

An Exchange hybrid configuration comes in various flavors. When using Microsoft Teams with on-premises mailboxes, you must know which hybrid option to choose. This session helps you understand the difference between the Exchange hybrid options and selecting the right option for your enterprise.
But what about the "How"?
Exchange Hybrid has dedicated prerequisites for your on-premises Active Directory and Exchange Organization. When your Exchange environment originates from Exchange Server 2010 or older, it will most likely have configuration artifacts that prevent a proper hybrid implementation on the first attempt.
This session helps you prepare your on-premises Active Directory and Exchange Organization for hybrid identities and Exchange, including proper network connectivity to Microsoft 365.

Keeping Your Exchange Server Pasture Secure en

Running an Exchange Server environment securely is not easy. Your Exchange servers are a very valuable target for hacker attacks. Zero-day exploits are the Achilles' heel of a local server environment. Securing your Exchange servers is not only about keeping Exchange up to date. There is much more to it. In this session, I show what measures are recommended to protect an Exchange server.

This session shows all the layers necessary to protect an Exchange Server. After the session, participants will be able to check in their own environment which measures are already active. An exchange of experiences on the protection measures plays an important role in this session.

Email mysteries of Microsoft 365 B2B guest accounts en

When collaborating with external partners, you most likely created B2B guest accounts in your tenant. You actively invited them using Azure Active Directory or added them to your Teams in Microsoft Teams. 
When your partner companies change their email domains, e.g., changing the primary domain brand, you might end up in a situation where you cannot send email messages any more. They receive a non-delivery notification, even when using the new email address.
During this session, you learn about the reasons for this by-design feature of Azure Active Directory and how to resolve it in your tenant.
