ooops <br />
<br />
I just removed them when they come back I will post it again<br />
<br />
<br />
I only have three (3) distribution groups and none have that address.<br />
<br />
I do not have any contacts listed.<br />
<br />
Any command I can run to check the email address?
</div>


<div>
You can run the below to try and find that email address:<br />
<br />
Get-Recipient -ResultSize unlimited | where {$_.emailaddresses -eq &quot;support@tgcsnet.com&quot;} | fl name, emailaddresses
</div>


<div>
Tim<br />
<br />
Thanks for the command<br />
<br />
<br />
[PS] C:\Windows\system32&gt;Get-Re<wbr />cipient -ResultSize unlimited | where {$_.emailaddresses -eq &quot;support@tgcsnet.com&quot;} | fl<br />

<br />
<br />
So why do I not see it in the list of mailboxes?<br />
<br />
<br />
Update<br />
<br />
From my outlook client I sent a test email and it bounced back<br />

delete that address from your outlook client auto-complete cache.<br />
<br />
also do you have a single domain, or do you have a parent (root) and child domain?
</div>


<div>
Tim<br />
<br />
The email is coming from my nagios server <br />
<br />
I just tried to send a test via my outlook to see the results<br />
<br />
I need to remove this from my exchange server<br />
<br />
Yes I have 3 domains all trusted one is a child domain <br />
<br />
The nagios server is on the parent domain <br />
<br />
How can I get rid of the address then I would like to recreate it
</div>


<div>
If that email is coming from a server, you will need to access that server and remove the settings on that server that is sending that email. That part is not an exchange issue. Run the following:<br />
<br />
Set-ADServerSettings -ViewEntireForest $true<br />
<br />
Next run this recreated cmdlet and it will show you what OU the object is located in your AD environment so that you can remove it or what ever you choose:<br />
<br />
Get-Recipient -ResultSize unlimited | where {$_.emailaddresses -eq &quot;support@tgcsnet.com&quot;} | fl name, emailaddresses, OrganizationalUnit, RecipientType, RecipientTypeDetails
</div>


<div>
Tim<br />
<br />
I looks like a public folder <br />
<br />

RecipientType &nbsp; &nbsp; &nbsp; &nbsp;: PublicFolder<br />
RecipientTypeDetails : PublicFolder<br />
<br />
Can I just delete that public folder by removing it from the ad ou? &nbsp;or do I need the command on exchange.<br />
<br />
Once I delete that public folder I should be able to create the mailbox &nbsp;with that email address.<br />
<br />
I believe that is from my old exchange 2010 setup &nbsp; <br />
<br />
What is the proper way to remove them?<br />

<div>
no you need to remove the public folder from the exchange. just access the Exchange admin center and delete that public folder or remove the email address from the public folder. once that is done, yes you can create a mailbox with that email address if you choose to.
</div>


<div>
if this was from your old 2010 environment then you will need to use ADSIEdit. see link below for help with removing public folder via adsiedit. if this public folder doesnt exist anymore and isnt in your 2016 environment you will need to use adsiedit but be sure because that is always the last resort.<br />
