You have a hybrid deployment that contains a Microsoft exchange Online tenant and anon premises Exchange Server 2019 server named Server1. Alt users use an email address suffix of @contoso.com.
On Server1, you create a new mailbox that uses an email address of [email protected] Users hosted in Exchange Online report that they receive a non-delivery report (NDR) When they attempt to send email messages to [email protected]. The NDR contains the following text: "User1 wasn't found at contoso.com." You verify that the Exchange Online users can send email successfully to the other mailboxes hosted on Server1. Users hosted on Server1 can send email to [email protected] successfully.
You need to identify what causes the email delivery to fail. What should you use?

All the users in your company are licensed for Microsoft 365 and connect to their mailbox from client computers that run Windows 10.
The users connect to Outlook on the web by using the following browsers:
Google Chrome
Microsoft Edge
Firefox
You apply restrictions for Outlook on the web sessions by using app protection policies in Microsoft Endpoint Manager, and then you deploy several Outlook Web App policies.
You need to ensure that the users can continue to connect successfully to their mailbox by using Outlook on the web.
What should you do?

You have a Microsoft Exchange Server 2019 organization that uses an Edge Server.
You plan to implement a hybrid deployment between Exchange Online and Exchange Server.
You need to ensure that all the email between Exchange Online and Exchange Server 2019 is sent by using the Edge Server.
Which two hybrid configuration topologies could you deploy to meet the requirements? Each correct answer presents a complete solution.

All the users connect to their mailbox by using a mobile device and Exchange ActiveSync.

What should you use?
