Plan for Exchange Online and Skype for Business Online

Thought experiment

In this thought experiment, demonstrate your skills and knowledge of the topics covered in this chapter. You can find answers to this thought experiment in the next section.

You are in the process of planning the alteration of the default spam filter used for your organization’s Office 365 tenancy. Currently, messages that have an SCL of 7 are being placed in a user’s junk email folders. Many of these messages are turning out to be legitimate, so for the next six months you want to have them moved to quarantine instead, where they can be examined by members of your team to check if they are being classified appropriately.

Recently, for reasons that aren’t entirely clear, several email accounts at your organization are being sent email from addresses in New Zealand. The contents of these emails are entirely in the Esperanto language. A variety of different IP addresses are used to send the emails, so filtering based on IP addresses hasn’t been entirely successful. You have been asked to ensure that all messages of this nature are classified as spam.

You are also in the process of planning an IMAP migration from a third-party on-premises messaging system that hosts 200 mailboxes to Office 365. You are reviewing the migration process.

You are looking at replacing the current practice of using litigation hold at Tailspin Toys when users are subject to discovery requests with instead switching to in-place hold. Management is especially interested in using the query functionality of in-place hold to locate items subject to discovery requests that are stored across multiple mailboxes. Management is also interested in what changes occur in terms of archive mailbox functionality when in-place hold is applied.

You are in the process of configuring Skype for Business Online using Windows PowerShell. You are interested in configuring public IM connectivity, disabling the Apple push notification service, and removing all of the currently blocked domains from the blocked domain list. To do this, you need to research the appropriate Windows PowerShell commands to accomplish these tasks.

With all of this in mind, answer the following questions:

  1. What steps do you need to take to modify the default spam filter policy to ensure that messages with an SCL of 7 are placed in quarantine?

  2. What steps do you need to take to modify the default spam filter policy to ensure that all messages in the Esperanto language that originate from New Zealand are marked as spam?

  3. Which Windows PowerShell cmdlet and parameter should be used to release a message to all recipients if that message is currently in quarantine?

  4. What is the first step in an IMAP migration?

  5. What step should an administrator take after all IMAP mailboxes that will be migrated are successfully synchronized to corresponding Office 365 mailboxes and are successfully performing periodic synchronization every 24 hours?

  6. When should the tenant administrator delete the IMAP migration batches?

  7. Which Exchange Administrator role must a user be a member of to configure a query-based in-place hold?

  8. When an in-place hold is applied on a mailbox, what is the new quota value assigned to the archive mailbox?

  9. Which Windows PowerShell command, including parameters and values, would you use to disable public IM connectivity?

  10. Which Windows PowerShell command, including parameters and values, would you use to disable the Apple Push Notification Service?

  11. Which Windows PowerShell command, including parameters and values, would you use to remove all domains from the blocked domains list?
