The six types of mail accounts that we can create are:

 

  • Alias email account (Free)
  • Mailbox (Requires License)
  • Distribution Group (Free)
  • Resource (Free)
  • Contacts (Free)
  • Shared (Free)
  • Office 365 Groups (Free)

 

NOTE: Office 365 Groups are designed to enhance collaborative work.

 

Alias Email (Free)

An alias is a way to disguise another Office 365 email address. Everything sent to an alias email address is received in the primary email account's inbox. You can create multiple aliases for the same email account.

Aliases can diversify a single email account, without having to pay for multiple inboxes. It can also be a way to organize your incoming email, with folders or labels for mail sent to a specific alias.

However, you can't send it from an alias address. Any reply will show your primary email address as the sender.

 

Mailbox (paid license)

 

This is where it all starts. When you purchase a license that includes Exchange Online, you will be getting a mailbox. This is what you add to your various mobile devices and log into every day with your email and password. Your Exchange Online mailbox is typically your primary email account.

Distribution Group (Free)

Distribution groups are emailing lists. When you create a distribution group, you add members and assign an email address to the group. If someone sends an email to the group email address, each member of the group will get a copy of the email. When responding to an email, the response can be from the individual member’s mailbox OR the distribution group email address.

 

Distribution groups can be used internally and externally. For example, you can use an internal distribution group for your departments or the entire staff ([email protected]; [email protected]). OR, you can use an external distribution group for your website ([email protected]; [email protected]; [email protected]). There are no credentials for this type of mailbox and they can’t be added to mobile devices. But, that’s fine since the email will be routed to a group member’s email account.

 

Resource (no cost, comes with subscription)

 

Resource mailboxes are for physical locations or equipment, like conference rooms or a video-conferencing device. You add the room or equipment’s email address to an email’s list of recipients like it were an actual person. Then, open the scheduling assistant in Outlook to see what times are available.

 

Contacts (no cost, comes with subscription)

 

Mail Contacts are email addresses (usually external) with contact information that are added to your organization’s Global Address List—a simple way of keeping frequent contacts available to your organization.

 

Adding a person to Contacts will also allow you to add that person to one of your organization’s distribution groups. For example, if you have an internal distribution group and want an outside consultant to also receive emails to the group, you add that consultant as a contact first, and then add him or her to the distribution group.

 

Shared (no cost, comes with subscription)

 

A shared mailbox is quite literally that. It’s a free mailbox that is created and assigned to users in your organization. There’s no end-user configuration, so once the user has been assigned to the shared mailbox, their Outlook will automatically add it below their primary inbox. It even comes with its own calendar.

 

When anyone emails the shared mailbox, the email will be delivered to the inbox of the mailbox and anyone assigned to it will be able to see it and act on it. Shared mailboxes are a great way to keep notifications from a service or your website from cluttering your primary inbox. Since it is defined as its own mailbox, you can export the entirety of its content as a PST file.

 

A few caveats:

 

Anyone assigned to the shared mailbox will have control over the mail. So, if one person deletes an email, moves an email to a subfolder or replies to an email from the inbox, it will be reflected across all assigned users.

Anyone assigned can reply to email and it’ll come from the shared mailbox email address. Sometimes, however, one person will reply but another won’t realize that and also send a reply.

There are no credentials to a shared mailbox, so you can’t add it to mobile devices. Don’t rely on a shared mailbox as a primary mailbox.

You do not get the typical “new email” popup like your primary email inbox. Here are a few workarounds.

Shared mailboxes only work for Outlook 2010 and above

 

The Shared mailbox is grossly underutilized, costing organizations fees for unnecessary licenses. For example: Let’s say you have a generic email address on your website for [email protected] that you want five people in your organization to receive. Too often, these are set up initially as Distribution groups. An email sent to the group address goes into the inbox of the 5 recipients, just like an email sent to them directly does. If they reply, it comes from the individual replying. Even if the user creates a rule to automatically move these to a subfolder in their inbox, it does not take long before this proves cumbersome.

 

Office 365 Groups (no cost, comes with subscription)

 

This is the newest type of mailbox from Microsoft designed to enhance collaborative work. The setup is just like a Shared Mailbox. You create a name an email address and assign users. When you create an Office 365 Group, you get a mailbox, shared calendar, a document library stored in the cloud, a OneNote Notebook, a SharePoint team site and a planner.

 

You can even invite external guests to Office 365 groups if you want to have them join in on the conversation and collaboration. They also allow you to create a conversation, so new members won’t miss out on previous emails. Conversations are stacked inside the workspace, and when you select one, you’ll see the original message PLUS all the replies in order, similar to a forum. You can even LIKE a message.

 

All the Office 365 Group features are found on Outlook 2016, the Outlook Web App, Outlook 2016 for Mac, Outlook for iOS/Android/Windows Phone, and the standalone app, Outlook Groups—available for iOS and Android.
