Create a User and Mailbox in Powershell

new-mailbox command

This command, when entered without parameters, will walk you through making an AD user with a mailbox, prompting you for the minimum required parameters.

While this might be enough to get you going, there are loads of extra flags that can be added. See below.

-Name <String> This is, of course, the mailbox name.
-Password <SecureString> The user’s password, stored as a SecureString meaning we cannot show it again later.
-UserPrincipalName <String> The user’s UPN name in AD, in the formatusername@domain.
-Alias <String> An alias, which will simplify finding the user in the GALThe Global Address List or GAL for short is used in the Microsoft Exchange email system. It holds all the information on all mail enabled objects within the organization. These can range from individual users to distributions groups. Microsoft Outlook connects to the GAL when you click the "To" email field when you would like to send an email.When Microsoft Outlook is in cached mode, it uses the Offline Address BookThe Offline Address book is a copy of all the mail enabled contacts, users and objects in the Microsoft Exchange organisation. The OABThe Offline Address book is a copy of all the mail enabled contacts, users and objects in the Microsoft Exchange organisation. The OAB is a copy of the Global Address List and all other additional address lists. The OAB is used when an Outlook client is in cached mode, when the Outlook client is not in cached mode it connects directly to the GAL. The OAB is generated once a day from the GAL so if a new user is created then there is a chance that outlook clients that are in cached mode will not get the update until the GAL and the OAB have synced. You can have more than one OAB, the OAB`s are distributed either via public folderA Public Folder is a folder that is stored within Microsoft Exchange on the Public Folder Database. The purpose of Public Folders is so that organisations can create folders to share email and files alike. Public folders can be mail enabled, so they can receive email without any managment.Once the email is in the folder, you can specify who can, read, edit and even see the public folder. or via Web ( IIS ). You can also specify via Mailbox Store what OAB a member of the mailbox store will receive. To force an update of the OAB run the PowerShell command Update-OfflineAddressBook YourOABnamehere is a copy of the Global Address List and all other additional address lists.

An email address consists of two parts, the local and the domain. So allen.whiite is the local part and techieshelp.com is the domain part. "Allen.White@Techieshelp.com" The local part can be anything you choose, however the domain part must always be what the email domain is set to. In-between the local and domain pats is an @ sign. A record called an MX record holds information where the email domain is. So if you send an email to allen.white@techieshelp.com the MX record tells the email where the mail domain techieshelp is. Once the email hits the mail server the local part of the email address kicks in. The mail box with the part "allen.white" then receives the email.
