Mail-enabled Public Folder Gets lots of spam.

hello all,
i don't know if this is to be expect but a public folder that we use is currently (has always) been receiving a large amount of spam emails, i can get some details about the public folder via powershell but i wondered if there was any way of cutting down
on the amount of spam that it receives.
i am guessing the settings for this being a public folder differ from those of a standard mailbox, but still are there any settings that allow me to set SCL reject / quarantine levels on a public folder?
Many Thanks

Hi,
As a workaround for this issue, you can create a transport rule to delete these spam which is added header "ESET SPAM DETECTED".

EXCH 2007: All email addresses forwarded to a mail-enabled Public Folder

I need to find all mailboxes and their aliaes that are setup to be Forwarded to a mail-enabled public folder. Is there an Exchange Mangement Shell script that I can run that will produce that list for me? Or some other way of finding those mailboxes/aliases?
Thanks
Matt

Hi Matt,
We can try the following command (proposing that Winnie is the Mail-enabled public folder):
Get-Mailbox | Where-Object { $_.ForwardingAddress -eq “Domain.com/Microsoft Exchange System Objects/Winnie” } | Select Name, ForwardingAddress, DeliverToMailboxAndForward
Hope it works.

Exchange 2013 delivery reports for mail enabled public folder

How can I get delivery reports for mail enabled public folders? Would I search the related public folder mailbox?

Hi,
When you track messages using Delivery Reports, you can only choose user mailbox when you select mailbox to search. Under the option "Mailbox to search", there is no mail-enabled public folder listed there for you to select from
the address book.
But you can search messages sent to or received from mail-enabled public folder.

Can't add a mail enabled public folder to allowed senders on a mail universal security group in Exchange 2010

Hello,
I'm trying to allow a mail enabled public folder permissions to send to a mail universal security group. In the past if I wanted to add a PF as an allowed sender I would do it via the AuthOrig setting on that group using adsiedit. I just noticed today
that if I add the PFs DN to that attribute of the group, nothing happens. No matter how long I wait the PF never shows up under the allowed senders list on the group. If you try and send as the PF you get a bounce about not being allowed to send to that
group. If I go back into AD and check, the PF is still listed under the AuthOrig attribute. I tried this on a few different groups and with a few different PF and I'm stumped. I think the last time I had to update this setting on a group
was before I installed roll-up 5 for SP3.
If I do the same test with a user, it works as it should and they show up in the allowed senders list.
If I take a group that isn't restricted to specific senders and add a PF DN to the AuthOrig attribute of the group, the button in the message delivery restrictions for that group in the EMC will change from all senders to only senders in the following list,
but the PF wont be listed in the box of allowed senders. If I remove it from the AuthOrig attribute the group will change back to allow all senders. It's really weird, so any help or light you can shed on this would be greatly appreciated.

Hello,
I check many threads and articles, but there is no related information to verify the issue.
If your purpose is that adding a mail-enabled public folder to allowed senders on a distribution group, there is a workaround method. You can create a new distribution group, and then add the public folder to the new distribution group, and add
the new distribution group to the Only senders in the following list field of the target distribution group.
Here is an article for your reference.

Mail Enabled Public Folder Issues after migration online

Hi
We have recently migrated our Legacy (Exchange 2010) Public Folder Infrastructure to Exchange Online - we have a hybrid setup, SSO and DirSync.
We initially had an issue where some of our mail enabled public folders had lost their link with the associated MailPublicFolder objects and as such could not receive email.
We resolved this issue ourselves however we are now experiencing a different issue which i believe should be easily resolvable however this isn't the case at the minute.
The issue is that when a user emails a Mail Enabled Public folder Exchange online is attempting to relay the email back to our onPrem servers. This is occuring for the bulk of our Mail Enabled Public Folders - we have ~1200 of these. The only
folders that are working as expected are those that had the initial issue above and for which we had to remove and re mail enable these folders. We also had to recreate any secondary smtp address for these folders. This accounts for 88 of our total
MEPFs.
I have checked the attributes on the MailPublicFolder objects for those that are not working and those that are functioning as expected. The only difference in these that I can see is that the MEPFs with the issue have a value set in the ExternalEmailAddressAttribute.
I have tried to programatically set this value to $Null however i receive the following error:
The external e-mail address $null is not an SMTP e-mail address.
I have also tried the following : set-mailpublicfolder -Identity "MEPF"-ExternalEmailAddress "<not set>"
with the same resultAttempting to use the following syntax -externalemailaddress @{remove=$oldAddress} returns the following error:
Cannot process argument transformation on parameter 'ExternalEmailAddress'.Cannot convert the "System.Collections.Hashtable" value of type"System.Collections.Hashtable" to type "Microsoft.Exchange.Data.ProxyAddress".
At present the only fix that I have for this is to take a copy of the email addresses for an affected public folder, Mail disable it, wait for the object to be cleared, re-enable the public folder as a mail public folder and then re-add the email addresses.
This is ok on an adhoc basis but not for the ~1200 folders that are affected. Especially when from what i can see it should be relatively straightforward to resolve this with a simple PowerShell script.
I do have a case open with MS for this but I am hoping that somebody here can help also.
Thanks
Joe

Ok so i fixed it myself.
The thinking here is that the ExternalEmailAddress was set using the Primary SMTP address while the Public Folders were on premises.
In order to get the required information we ran a script to export all the MailPublicFolder objects which had a value in the ExternalEmailAddress attribute. We exported the Name, ExternalEmailAddress and GUID
We then ran a second script to export the Identity, MailRecipientGuid from Get-PublicFolder -recurse.
The MailRecipientGUID is what ties the Mail Enabled Public folder to the MailPublicFolder object.
Using Excel I then matched the two up and created a csv file with the Identity Attribute from the get-PublicFolder command and the ExternalEmailAddress Attribute from Get-MailPublicFolder.
The following script then used this csv file to first Mail Disable the Public Folder, then Mail Enable the Public Folder.
Once these steps have been completed the final stage is to add the SMTP address back in to the Public folder.
To do this it is necessary to retrieve the new MailRecipientGUID and use it to return the MailPublicFolder for the Set-MailPublicFolder command.
I was happy to use this script after i tested with a small subset of the data. It is provided as is with no guarantee that it will be suitable for you to use and any use of this script is at your own risk.

When sending e-mail messages to a mail-enabled public folder that have been replicated from old Exchange Server 2000/2003/2007, Exchange Server 2010 environment mails are rejected with NDR.

Hi, I would like to share with you issue that I’ve solved regarding mail-enabled PF that migrated from Exchange 2000/2003/2007 to 2010, I’ve searched & contacted my MVP leader – there’s no official KB regarding this issue right
now, so I’m posting here in order to share this among others.
Note: There’s article(s) that talked about PF replication from Exch2000/2003/2007 to 2010 – this is the same issue as well.
Symptoms
E-mail messages that been sent to mail-enabled public folder in Exchange Server 2010 environment rejected with the following NDR:
“#< #5.2.0 smtp;554 5.2.0 STOREDRV.Deliver.Exception:ObjectNotFoundException; Failed to process message due to a permanent exception with message The Active Directory user wasn’t found. ObjectNotFoundException: The Active Directory
user wasn’t found.> #SMTP#”
Sometimes Exchange Server 2010 is documented as well Event ID 1020 on the Event Viewer with this information:
“Log Name: Application
Source: MSExchange Store Driver
Event ID: 1020
Level: Error
Description:
The store driver couldn’t deliver the public folder replication message "Hierarchy ([email protected])" because the following error occurred: The Active Directory user wasn't found.”
Cause
In an environment where Microsoft Exchange Server 2000 or Microsoft Exchange Server 2003 previously existed, and all those servers have been removed, there is a chance that an Administrative Group (First Administrative Group or another custom Administrative
Group) remains with a Servers container, but no servers inside it.
During replication, when the Exchange 2010 Store Driver sees the empty Servers container in Active Directory, it's expecting a System Attendant object inside the container and when it is not found the error occurs.
Resolution
To work around the issue, delete the empty Servers container. This can't be done through Exchange System Manager. Use the ADSI Edit tool to remove it using the following steps:
Warning If you use the ADSI Edit snap-in, the LDP utility, or any other LDAP version 3 client, and you incorrectly modify the attributes of Active Directory objects, you can cause serious problems. These problems may require you to reinstall Microsoft Windows
2003 Server, Microsoft Windows Server 2008, Microsoft Exchange 2010 Server or both Windows and Exchange. Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be solved. Modify these attributes
at your own risk.
1.
Start the ADSI Edit MMC Snap-in. Click Start, then
Run, and type adsiedit.msc, and then click OK.
2.
Connect & Expand the Configuration Container [YourServer.DNSDomainName.com], and then expand
CN=Configuration,DC=DNSDomainName,DC=com.
3.
Expand CN=Services, and then CN=Microsoft Exchange, and then expand
CN=YourOrganizationName.
4.
You will see an empty Administrative Group. Expand the
CN=YourAdministrativeGroupName.
5.
Expand CN=Servers.
6.
Verify there are no server objects listed under the
CN=Servers container.
7.
Right click on the empty CN=Servers container and choose
Delete.
8.
Verify the modification, and try to send again the E-mail to the mail-enabled public folder.
Applies to
Exchange Server 2010, Standard Edition
Exchange Server 2010, Enterprise Edition

| E-mail: [email protected]

Sounds like you are looking in the wrong Administrative Group container which is why you are seeing your Exchange 2010 servers in there.
When you install Exchange 2003 only you will see a container named by default as "CN=First Administrative Group" container. But this could be named anything if you changed the Organization Name on the installation when you installed the first
Exchange 2003 server into the domain/forest.
You will notice that when you install Exchange 2010 part of the AD setup is to create a new configuration container and is named by default "CN=First Administrative Group (FYDIBOHF23SPDLT)".
So it sounds like you are not looking in the right location within ADSIEdit.
You may find the following article also helpful for this issue which is the same resolution:
http://blogs.technet.com/b/sbs/archive/2012/05/17/empty-cn-servers-container-causing-issues-with-public-folders-on-small-business-server-2011.aspx
I recommend though that you ensure your Exchange 2003 servers are fully uninstalled or no longer present in your environment before you go deleting the Servers container though.. The following Microsoft article will help with this:

Mail-enabled Public Folders Not showing as Mail-enabled

We have completely migrated from Exchange 2003 to Exchange 2007 (SP1 Rollup 5). Many, but not necessarily all, of our mail-enabled public folders do not appear to be mail enabled in either the 2007 PF Management Console or the Shell, yet they are mail-enabled in the 2003 System Manager and we can send email to them. If we mail-enable a folder in the EMC, it blows away any previous email addresses and creates a new one.
Any reccomendations on how to get 2007 to accurately display the properties of these folders??

Issue description: Mail-enabled public folders can’t show as mail-enabled status in the EMC and EMS after migrated from exchange 2003 to exchange 2007, right?
Troubleshooting:
1.       Please use “Get-PublicFolder” to check the output of a migrated problematic public folder, see if the value of “MailEnabled” is “True”
Get-PublicFolder -Identity "\problematic public folders name"
2.       Please find out where migrated problematic public folder objects exist in the AD. By default, mail-enabled public folders should stay in the “Microsoft Exchange System Objects” container. You can use ADUC or ADSIEditor to verify their current location
3.       I assume that link between mail-enabled public folder and its AD object has been broken during the migration. So, I suggest you to create a test mail-enabled public folder, and compare the attributes of its AD objects with the problematic one with ADSIEditor. This will tell us if there are any incorrect values in the attributes of the problematic public folder objects
a.       Launch the ADSIEditor (Start->run-> ADSIEditor.msc)
b.      Locate problematic mail-enabled public folder object and the new created one
c.       Right-click the objects and select “Properties”. Then, compare their attributes in the “Attribute Editor” tab
Notes: Please select all three checkboxes in the “Attribute Editor” tab, it will save more time during the comparison

Mail-enabled Public Folders not accepting email from external users after migrating from Exchange 2003

We are in the process of trying to decommission our Exchange 2003 server, all of the replicas have been moved to the Exchange 2010 SP3 servers. However, each time we dismount the public folder store on the 2003 server (just to see what won't work) nobody
from outside the company can send mail to the mail-enabled public folders (we use these to communicate with vendors and customers).....they sit in the 2003 mail queue until I remount the store.
I have mail disabled them on the 2010 PF server, waited a few hours and then mail enabled them again. Same issue. Interesting to note is that when the PF store on the 2003 server is dismounted people inside
the company can still send to the mail-enabled PFs (which is good). I am stumped.

SPAM and Exchange 2010 Mail-enabled Public Folders

Is there a way to determine if mail sent to our Exchange 2010 mail-enabled Public Folders by our customers is ever rejected because it was tagged as spam? The concern is that we might not be receiving some email. We rely on the mail-enabled PF's
heavily, but since they aren't a mailbox there is no Junk E-mail folder to check. We do not have the resources to check EOP on a regular basis throughout the day, and the customer would not get an NDR or anything like that.

Hi,
You can consider to use Message Tracking tool under EMC -> Toolbox to track these messages.

Mail-enabled Public Folders not showing as enabled in PFMC or EMS

Good morning
I have some PF's that are mail enabled, but running the Get-PublicFolder cmdlet shows "mailenabled" attribute as False. Also, in the PF Management Console, the folder shows as not mail enabled (with an option to enable it).
I found this thread that seems to be related:
http://social.technet.microsoft.com/Forums/exchange/en-US/918aad03-c96f-4023-89cc-ec2c66e51b93/mailenabled-public-folders-not-showing-as-mailenabled?forum=exchangesvrgenerallegacy
I'd like to do some testing, but recreating this issue with a test PF is actually really hard.
Does anyone know a way to force that "mailenabled" attribute to False after mail-enabling a PF? I can't find any ADSI attribute that is obvious. I changed MsExchRecipientTypeDetails to <not set> but that didn't do it...
**UPDATE** I just found out that msExchMailboxGuid is missing from that object. Does anyone have any kind of suggestion for how I can find the Guid of the mailbox that is no longer associated with this PF?
**UPDATE 2** I have found other PF's that are missing this attribute, but they are not displaying any symptoms. They are showing as mail enabled in the EMS and PFMC. So I guess this isn't a required attribute.
Could anyone explain the purpose of this attribute for mail-enabled public folders? I just assumed it was required.
Thanks!

Hi,
Do you migrate these mail-enabled public folders from previous Exchange server to Exchange 2010?
Please check if you can see the SMTP address for mail-enabled public folders via Properties of Public folders.
Please check if they show in the Microsoft Exchange System Objects in ADUC.
Besides, I recommend you mail disable the public folder and then mail enable it again to check the result in the Public Folder Management Console.
For a mail-enabled recipient, a minimum set of attributes is required to make all Exchange components work properly. For example, a mail-enabled entry (a user, contact, group, or public folder) has to have at least these attributes: mailNickname, legacyExchangeDN,
and displayName. Without the mailNickname attribute, an object is not considered mail-enabled.

User not able to save e-mails from public folder

Hi,
I have a email user with a complain that she is not able to save some e-mails from public folder, nor their attachments, nor to forward them to her own inbox. This happen not for all emails but randomly for some emails in her public folder.
She can open and read but got following error message , while trying to save the attachment of the email
"Cannot save the attachment. You do not have sufficient permission to perform this operation on this object. See the folder contact or your system administrator"
The following error occurred when she trying to forward the email.
"Cannot open this item. You do not have sufficient permission to perform this operation on the object. See the folder contact or your system administrator"
I have tried to grant "Edit All" in the write permission area, later tried with "owner permission" too but still having the same errors.
I found out in some occasion when the email is read only then it cannot be forwarded, copy or print the contents.
I see emails in the public folder appeared with "Read only" but most of them can be saved and forward, only few appear with errors for the user. I did checked the emails "Restrict permission" setting and that display
with "No restriction".
How can I get rid of the errors and allow the user to save the attachment and also save the email in different location of the public folder.
Thanks
Selvem

Hi,
Please check if you can move these affected messages to Inbox folder.
And please check if the issue persists in OWA.
Does this issue affect only one user?
If this issue only affects one user, you can recreate Outlook profile to check result.

I am getting lots of spam and dont know what settings to use

Hi All
I am not the greatest on my Mac but I am getting a lot of spam and not sure what settings I should apply to try and reduce the amount of spam I receive.
Kind Regards
Ian

Whatever email client you are using, the spam settings are always found in the client's Preferences. Some say Junk Mail while other may say Spam.

I use yahoo business mail, but I am getting hundreds of spam message on my Mac Air. I don't get them on my iPhone. Ive run a Malware app. Does anyone know how I can stop getting all this junk mail. Thanks

How do i stop getting spam coming to my mailbox using Yahoo Business mail? I use Yahoo Biz Mail, but am now getting a huge amount of spam. I don't get any using the same address on my iPhone. I ran a Malware app - didn't help. Any ideas??

Hello SkeeterOz,
It sounds like you’re seeing spam emails in the Mail application on your MacBook Air, but you aren’t seeing those spam emails on your iPhone. The article linked below will walk you through enabling Junk Mail filtering in Mail and specifying what you want to do with the emails that are filtered.

Mail app public folder

Is it possible to use public folder, contact in public folder et group of contact in public folder with Mail App ?
Mail App version 6.3 (1503) and OS X 10.8.3
Exchange Server 2010

I don't quite understand what you are describing, but Mail uses contacts in the Contacts application and previously sent email addresses in its own Previous Recipients database. It cannot use anything not in one of those two places.
