It could be due to old settings, also if Outlook version is used in sync with 365, the older folder can appear. Thru registry also this setting can be changed.

The grayed one is the default, created when the mailbox was first provisioned, that's why Outlook is not allowing you to delete it. The second one is most likely created after you configured the account on some mobile device or similar. You can confirm this via PowerShell:<br />
<br />

<pre><code class="code-1 nolinks" id="code-20-41834733-1"><span>Get-MailboxFolderStatistics user@domain.com  | ? {$_.Name -like &quot;*Junk*&quot;} | ft Name,FolderType</span>
</code></pre>
<br />
The one marked as &quot;user created&quot; is the one you should delete, and Outlook should allow you to do so.
</div>


<div>
neither folder says user created??
</div>


<div>
at one point not too long ago I had to create a new out look profile due to some reason. I am not sure if that has to do with it and I do not know nor I would like to mess with the registry . I am not as smart as you .
</div>


<div>
how do I know which folder was there before I created the new outlook profile?
</div>


<div>
Creating a new Outlook profile should not have caused this. Just to clarify, you are using an Exchange account, configured as such (i.e. no IMAP)? Do you have this mailbox configured on some mobile device?
</div>


<div>
yes I have outlook on my note 4 galaxy Samsung. I do not think it is imap though. I can not remember.
</div>


<div>
Check the settings of the mail app you are using on the Galaxy, here's a similar discussion on technet forums: <a href="https://social.technet.microsoft.com/Forums/office/en-US/d00cab48-d386-4e84-b4c2-d872d77bd26e/outlook-creates-extra-folder-called-junk-in-mailbox" rel="ugc nofollow">https://social.technet.microsoft.com/Forums/office/en-US/d00cab48-d386-4e84-b4c2-d872d77bd26e/outlook-creates-extra-folder-called-junk-in-mailbox</a>
</div>


<div>
The junk folder is in outlook 2016 part of office 365 in my desk top not in my Samsung Galaxy Note 4!!! &nbsp;Please help sorry for delay in reply
</div>


<div>
Yes, once the folder is created it will be visible in Outlook/OWA as well. But if it's indeed the mobile device that's creating it, it will simply reappear after you delete it, that's why I'm suggesting to check the settings on the device.
</div>


<div>
ok let me look again. thank you my friend
</div>


<div>
do I need to uninstall outlook from my galaxy note 4 ? to solve my problem
</div>


<div>
Were you able to delete one of the folders? If it doesnt come back, there's no reason to uninstall it. But if you are also using the default mail app on the device, check the settings as detailed in the thread I linked above.
</div>


<div>
I removed the Junk folder from the email client in my note 4 and was able to delete the extra junk folder from the outlook office 365 2016 however the remaining junk folder the &quot;delete Folder&quot; option is still greyed out . WHY ?????
</div>


<div>
furthermore there are 3 other folders Deleted , Draft and Sent items the delete folder option is greyed out. I created a new junk email folder called it junk email Beta. I transferred all the junk email to it and it shows delete folder as NOT greyed out but the original Junk email folder even though it is empty still greyed out the delete folder just like the other three folders that I just mentioned.
</div>


<div>
Those are the default folders, you cannot delete them. As long as you only have a single Junk E-mail folder now, you are good to go,
</div>


<div>
why some folders can be deleted and some you can not ?
</div>


<div>
Because those are &quot;default&quot; folders, special ones that are necessary for the mailbox to function properly. Outlook and other email clients recognize them as such and will prevent you from deleting them. Even if you manage to delete them via the client or some other tools, they will still be present/recreated server side.
</div>

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.

Microsoft Outlook is a personal information manager from Microsoft, available as a part of the Microsoft Office suite. Although often used mainly as an email application, it also includes a calendar, task manager, contact manager, note-taker, journal, and web browser.

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.

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

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.

Email Protocols

An email client, email reader or more formally mail user agent (MUA) is a computer program used to access and manage a user's email. A web application that provides message management, composition, and reception functions is sometimes also considered an email client, but more commonly referred to as webmail.
