Your MX record pointed to Exchange Online Protection and you observed that lot email bounced back which was send to an invalid recipient in your organization; you find a solution to stop this, what you will do?

The Directory Based Edge Blocking (DBEB) feature in Exchange Online and Exchange Online Protection (EOP) lets you reject messages for invalid recipients. DBEB lets admins add mail-enabled recipients to Office 365 (Azure AD) and block all messages sent to email addresses that aren’t present in Office 365.

Changing the accepted domain as Authoritative in Exchange Online enable the Directory Based Edge Blocking (DBEB) feature.

What are Accepted Domains and Remote Domains in Exchange Online?

Accepted Domains and Remote Domains are same as On-Premise Exchange. When we add a domain as accepted domain, then the user with that domain can send and receive email.

There are two types of Accepted Domains, Authoritative and Internal Relay. Authoritative option means that email is delivered to email addresses that are listed for recipients in Office 365 for this domain. Emails for unknown recipients are rejected. Internal Relay means that recipients for this domain can be in Office 365 or your own email servers. Email is delivered to known recipients in Office 365 or is relayed to your own email server if Office 365 does not know the recipients.

Remote Domain control the types and the format of messages that your users send to domains outside of your Exchange domain. Here are some of those reasons:

  • Restrict users from forwarding emails to other domains.
  • Reject automatic messages, such as non-delivery reports and out-of-office replies.
  • Send out-of-office replies as those received by people inside your organization.
  • Your users frequently send email to a company that supports limited email formats, and you would like to make sure all emails sent to that organization are sent in a format that they can read.

What are the recipients that are supported in Exchange Online? How to convert a Shared mailbox to User Mailbox?

As like Exchange On-Premise, Exchange Online Supports Users Mailbox, Shared Mailbox, Distribution Group, Mail enabled security group, dynamic distribution group, mail contacts, mail users, Room Mailbox and Equipment Mailbox. We can select the Mailbox in Exchange Online Admin center and we will see an option to convert to Shared Mailbox.

What is clutter?

Clutter is a feature in Office 365 designed to help users focus on the most important messages in their Inbox by moving lower priority messages into a new Clutter folder.

You have a requirement for a set of users to view only a set of recipient address in Address Book. How you will achieve it?

We can create Address book policies to achieve this. Address book policies (ABPs) allow you to segment users into specific groups to provide customized views of your organization’s global address list (GAL). When creating an ABP, you assign a GAL, an offline address book (OAB), a room list, and one or more address lists to the policy. You can then assign the ABP to mailbox users, providing them with access to a customized GAL in Outlook and Outlook Web App. It is same like GAL segmentation to have multiple GAL in On-Premise Exchange.
