Enable External Senders to send emails to an Office 365 Group

Office 365 Groups is an upgrade to the Distribution List in Exchange. The difference is now members can see what the past conversations were even if they joined the group much later.

Office 365 Groups by default do not allow external senders to send emails to the group. If you require external senders to email Into a group, you would have to enable it.


All you have to do is goto the Exchange Admin Center, click on “Recipients” from the Left Navigation and then select “Groups” from the top nav. Click on “Create a new Office 365 group.” Then you would see a page similar to the above screenshot. If you need to enable external senders to email to the group then make sure you enable the option highlighted.



Exchange Admin-Message Trace

The Message Trace in Exchange Admin Center allows one to check the status of messages that were sent to a specific recipient or sent from a specific sender. It shows whether messages were successfully delivered or not.

One must note that it would also show emails delivered to the Junk Folder. In that case the status would show Filtered for Spam.


To Setup Forwarding from a distribution list to an Office 365 Group

There is not a straight forward process to forward email from a distribution list to an Office 365 Group. You would need to follow these steps in order to do that-

  1. Create a Shared Mailbox.
  2. Add the newly created Shared Mailbox as a member of the distribution list. Doing so would allow the Shared Mailbox to receive email from the distribution list.
  3. Set up Email forwarding in the shared mailbox to forward email to the Office 365 Group. Now there is a point to be noted here, you would not be able to do this in the Exchange Online Admin Center. You would need to use Power Shell in Order to setup forwarding to an Office 365 Group.

Set-Mailbox shared -ForwardingSmtpAddress <EmailAddress> -DeliverToMailboxAndForward $true

Connecting to Exchange Online using PowerShell

Exchange Online is part of the Office 365 Suite. The Exchange Online Management Center is used to manage and maintain the Exchange online mailboxes. Power Shell can also be used to accomplish these tasks. In order to connect to Exchange Online using Windows Power Shell, one would have to follow these steps-


  1. Run Windows Power Shell as an Administrator.
  2. Run this cmdlet Set-ExecutionPolicy RemoteSigned
  3. $UserCredential= Get-Credential
  4. A Windows PowerShell dialog box would pop up, type in your Office 365 Credentials.
  5. Then run this cmdlet $Session= New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $UserCredential -Authentication Basic -AllowRedirectionScreenshot (117).png
  6. Import-PSSession $Session
  7. Once you have completed your work, you can close the session by Remove-PSSession $Session

Disabling Outlook Web App for a User in Microsoft Exchange

Outlook Web App is the browser version of the Mailbox. One could open their email on a browser rather than downloading the Outlook Client on their Computer. This has got it’s pros and cons. It is normally enabled by default for an Organization. Nowadays many Organizations are considering disabling the Outlook Web App Feature. The reason for this is due to security concerns. When one tries to access Outlook using the Outlook Web App on a public computer, there is a potential risk of login credentials getting exposed.

In order to Disable the Outlook Web App feature for a user, it can be done in two ways-

  1. Exchange Admin Center
  2. Power Shell

In the Exchange Admin Center, one would have to follow these steps-

  1. Click on Recipients
  2. Activate the Mailboxes tab
  3. Select the Mailbox which you would like to disable the Outlook Web App Feature.
  4. Click on the Pencil Icon
  5. A new Window would pop up. Now click on Mailbox Features.screenshot-80
  6. Under Email Connectivity, click Disable.

This can be also done on the page where you would get the list of mailboxes. The Steps are as follows-

  1. Launch the Exchange Admin Center.
  2. Click on Recipients.
  3. Activate the Mailbox Tab.Screenshot (81).png
  4. Select the Mailbox which you would like to disable the Outlook Web App Feature.
  5. On the Right Pane under Email Connectivity, click Disable.

Power Shell can also be used to Disable a Mailbox on a Per- User Basis.

For Example if we want to disable Outlook Web App (OWA) for a Mailbox with the Primary Email Address as . The Power Shell Cmdlet for disabling OWA would be-

Set-CasMailbox -OwaEnabled $False


Cas in ‘CasMailbox’ stands for Client Access Server

The Name of the cmdlet is Set-CasMailbox. The reason we are applying the “Set” Action on the Mailbox is because we want to modify the existing properties of the Mailbox.

The Parameter applied to the cmdlet is ‘OWAEnabled’. It has two possible values- $true and $false. If the parameter is set to $True, it means that Outlook Web App is Enabled and if the parameter is set to $False, it means that Outlook Web App has been disabled.

The Advantages of using PowerShell over the GUI is that the action can be applied to multiple Mailboxes at once. For Example we can write a command to disable OWA for the Entire Organization. The Power Shell cmdlet would be-

Get-Mailbox ¬†-ResultSize Unlimited -Filter {RecipientTypeDetails -eq “UserMailbox”} | Set-CasMailbox -OwaEnabled $False

Here we are using two cmdlets. The result of the First Cmdlet is given as an Input to the Second cmdlet. The first cmdlet ‘Get-Mailbox’ retrieves all the Mailboxes in the Organization. The Second cmdlet ‘Set-CasMailbox’ is used to Disable OWA for all the Mailboxes obtained from Get-Mailbox

Order of execution of Anti Malware Policies

In Microsoft Exchange one can create Anti Malware Policies. Anti Malware Policies are policies which prevent Malware from entering your organization. Malware are attachmentso in your email which may cause harm to your computer. 

One of the policies which could be set is  in case a Malware is detected on the email , all the attachments are deleted. Now there is an order in which Anti Malware Policies are executed on Microsoft Exchange. The Anti Malware Policies which were created the earliest are executed first and the ones created more recently are executed the last.
