Hybrid Office 365 Migration from your own Exchange Server

Simply stated, a hybrid deployment assist companies in connecting their existing email system, such as Microsoft Exchange, to an online version called Exchange Online in Microsoft 365. It's like building a bridge between your old email setup and the new online version.

Imagine you have a typical setup with your email system running on your office computers (on-premises). Now, you want to use some cool features available online. That's where Exchange Online comes in. However, you don't want to lose what you already have, right? So, a hybrid deployment allows you to keep using your old system while also enjoying the benefits of the new online version.

Here's what happens:

• You set up a special server called Azure AD Connect. This server ensures everyone can use the same username and password for both their old email and the new online version. It's like having one key for two locks!
• Next, you make sure everything is ready for the hybrid setup, for instance, checking your internet connection and the setting up of some software tools.
• Finally, you apply a special tool called the Hybrid Configuration wizard to choose how you want yourhybrid setup to operate.

Once everything is set up, here's what you get:

• You can log in to both your old and new email systems with the same username and password. No need to remember different ones!
• Your email addresses remain the same, whether you're using the old system or the new version.
• All outgoing emails go through your office system, even if you're using the online version. It's like having a central hub for all your emails.
• You can easily see whether your coworkers are free or busy, no matter which system they're using. You can also track messages and get helpful tips for your emails, regardless of where they're sent from.
• You use the same web address to access your emails, whether you're using the old system or the new version.
• So, with a hybrid deployment, you get the best of both worlds – the reliability of your old system and the convenience of modern online features!
