Please, use this one:<br />

<pre><code id="code-20-42819162-1">get-mailbox -filter *  | select Name,EmailAddresses  | Export-csv D:\All_emails.csv -NoTypeInformation
Get-UnifiedGroup | select Name,@{L=&quot;EmailAddresses&quot;; E={$_.EmailAddresses -join &quot;,&quot;}}  | Convertto-csv -notypeinformation | select-object -skip 1 | out-file D:\All_emails.csv -append</code></pre>

Dear Experts,<br />
<br />
I tried to export out my customer's address list from the office365 ecp but it just shows the user's email addresses only.<br />
<br />
How about those in the distribution group or if a user has access to more than one email accounts?

How to export all the email addresses of an organisation?

An email client, email reader or more formally mail user agent (MUA) is a computer program in the category of groupware environments used to access and manage a user's email. A web application that provides message management, composition, and reception functions may internally act as an email client; as a whole, it is commonly referred to as webmail. Likewise, email client may be referred to a piece of computer hardware or software whose primary or most visible role is to work as an email client. Email clients can also have other systems, like calendars, notes and contact managers.

Email Clients

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Office 365 is a group of software plus services subscriptions that provides productivity software and related services to its subscribers. Office 365 allows the use of Microsoft Office apps on Windows and OS X, provides storage space on Microsoft's cloud storage service OneDrive, and grants 60 Skype minutes per month. Office 365 includes e-mail and social networking services through hosted versions of Exchange Server, Skype for Business Server, SharePoint and Office Online, integration with Yammer, as well as access to the Office software. All of Office 365's components can be managed and configured through an online portal; users can be added manually, imported from a CSV file, or Office 365 can be set up for single sign-on with a local Active Directory using Active Directory Federation Services.
