<code bash| New distribution group>
new-distributiongroup -name "Group Name" -Alias "groupalias" -type "distribution" -organizationalunit example.com/OU_Name/Distribution Groups" -primarysmtpaddress "group.name@example.com"
</code>

User named: First Last at external.com
<code bash| New mail contact>
New-MailContact -Name "First Last" -ExternalEmailAddress "first.last@external.com" -alias "flast"
</code>

User named: First Last
<code bash| New Mailbox and New AD user at the same time>
New-Mailbox -Name "First last" -Alias "flast" -FirstName "First" -LastName "Last" -DisplayName "First Last" -OrganizationalUnit "example.com/users" -UserPrincipalName "flast@example.com" -Password (ConvertTo-SecureString -String 'password_complying_to_ad_password_policy' -AsPlainText -Force)
</code>
**-Name** will be used as the **-DisplayName** if no display name is specified

<code bash| List users with no mailbox>
Get-User -RecipientTypeDetails User -Filter {UserPrincipalName -ne $null } -ResultSize unlimited
</code>

<code bash | Enable mailbox for user with no mailbox>
Enable-Mailbox -Identity flast@example.com -Alias "flast" -DisplayName "First Last" -Database "mdb01"
</code>
**-Alias, -DisplayName and -Database** aren't mandatory and can be populated automatically

<code bash| Get user info>
Get-Mailbox -Identity flast | Format-List Name,DisplayName,Alias,PrimarySmtpAddress,Database
</code>

Get distribution list members
<code bash>
Get-DistributionGroupMember -Identity GroupName
