By establishing a hybrid deployment, you can extend the feature-rich experience and administrative control you have with your existing on-premises Exchange Server organization to the cloud. A hybrid deployment also offers support for a cloud-based archiving solution for your on-premises mailboxes with Exchange Online Archiving and may also serve as an intermediate step towards a complete migration of your on-premises mailboxes to Exchange Online.

Microsoft Exchange (2)
Customizing and configuring an Exchange organization has been a daily task for Exchange administrators for years. In a local Exchange organization, you can customize mostly anything you like. There is no requirement for enabling the organization for customization. But in Exchange Online, the situation is different.
Recipient Limits in Exchange Online
Microsoft has about 258 million paid seats for Office 365, The Verge reported in April 2020. As a “shared medium” for a lot of organizations around the globe, it should be clear that there must be limits in the Microsoft 365 ecosystem, e. g. message size limits or Teams member limits. In this blog we are covering recipient limits in Exchange Online.
Managing Exchange Online using the EXOv2 module
Exchange Online Automation with EXOv2 module
In my first part of Exchange Online Automation with EXOv2 module, I covered how you can use Dave’s PowerShell module for cutting down the Azure AD application registration and configuration. Also, how and why you should store your secrets in Azure Key Vault.
The same question as been asked for a long time: How can EXO recipient management be done without the need of administrative accounts?
New Features for Single Item Recovery
There's a lot of content out there about backups for Office 365. I, personally, have written and spoken a lot about backups for Office 365. If you ask 10 experts, you will probably get 10 different opinions about how, or why, or what you should or should not backup in Office 365. Depending on the day (and let’s be honest, who I am working for) I may give you different answers myself.
Reply All Storm Protection in Exchange Online
Twenty-five years (!) ago I was working for Microsoft. One morning we got this message with a subject line “Why am I on this mailing list? Please remove me from it.” From someone, followed by an email saying “Me Too!”, and another one with “Me Too!” and another one, and another one, followed by email with “People stop with the replay” multiple times. Before we knew it, the Exchange environment was brought to a standstill because of the enormous amount of email sent via this Distribution Group and nobody was able to send email anymore. It took a couple of days before the Microsoft internal IT staff had fixed this.
Microsoft postponed deprecation of Basic Authentication in Exchange Online for existing tenants. Jaap Wesselius (MVP) wrote about this topic already here and explained what Modern Authentication means and how you can monitor existing usage of legacy auth (which Basic authentication basically is).
Why Modern Exchange Hybrid?
The question of why should I implement Exchange Modern Hybrid is justified. Exchange Modern Hybrid is specially designed to simplify implementing Exchange Hybrid Mode by eliminating the requirement for inbound HTTPS connections to an on-premises Exchange organization. The technical specifications for Classic Exchange Hybrid are sometimes unsuitable for enterprises. You can read more about the differences between the two Exchange Hybrid modes in ENow's blog post, "What are your Hybrid Options."
