Public folders in Mixed Exchange environment

We are running
- Exchange 2007 - a LOT of users and a LOT of PF
- Exchange 2010 ( currently very limited )
- Exchange 2013 - about 2000 users
The Exch 2010 environment was pretty much stood up and had 30 pilot accounts on it before we decided to go to Exch 2013 instead/ These account have since been migrated to Exch 2013, so it is currently VERY LIMITED use.
We have a large number of Public Folders in Exch 2007. We do not plan on using the Exch 2013 model of shared mailboxes, but are looking to create the Public Folders in the Exch 2010 environment so we can close down Exch 2007.
The bulk of my users are still on 2007, but I have a couple thousand already moved to 2013. All users can access the Public Folders on Exch 2007.
We have not created any Public Folders in Exch 2010 yet. Practically all the posts I read state to enable replication for the 2007 folders to get them to 2010, but what about NEW folders. If I create a new folder on Exch 2010, without configuring replication
to 2007, will the Exch 2007 and Exch 2013 users be able to access it?
Tom

For Exchange 2010 or Ex2007 you will need to setup the replication but for Exchange 2013 it is different.
what is your plan,, do you want to keep them on 2013 or 2010 or you want keep the mix environment?
If I create a new folder on Exch 2010, without configuring replication to 2007, will the Exch 2007 and Exch 2013 users be able to access it? Yes you can still access them. You will need to setup the database for the default public folders.

Public folders in hosted Exchange 2013

Hi,
Is it possible to setup public folders for a tenant i Exchange 2013, eg. with custom id 0 set or something like that?
Thanks!

Hi,
If you want to deploy public folders in an Exchange 2013 multi-tenant environment, you can create a public folder mailbox per tenant.

How to migrate public folders from legacy (exchange 2003 ) to exchange 2010

How to migrate public folders from legacy (exchange 2003 ) to exchange 2010 . Please suggest ?
Aditya Mediratta

Hi Aditya,
please find the answer in
http://blogs.technet.com/b/agobbi/archive/2010/08/04/how-to-move-public-folder-from-exchange-2003-to-exchagne-2010.aspx
Please ensure you have a working mailflow from Exchange 2003 to 2010, vice versa, before you begin.
Basically it's the same procedure as adding some PF Database in E2K3; just
run .\AddReplicaToPFRecursive.ps1 -server "Exchange 2010 Server" -TopPublicFolder "\" -ServerToAdd "Exchange 2010 Server"
Wait until some initial data started to replicate; after that run
Update-PublicFolderHierarchy -Server "Exchange 2010 Server"
After replication has finished you can do a
.\MoveAllReplicas.ps1 -Server "Exchange 2003 Server" -NewServer "Exchange 2010 Server"
Please let me know if it worked.
Kind regards,
Martin

Public Folders on Microsoft Exchange

Is there a way to access public folders on Microsoft Exchange. This can be any version of ColdFusion and any version of Exchange. Right now I have CF9 and Exchange 2007, but we are looking to upgrade to CF10 and Exchange 2013.

UPDATE: (WORKING)
I tried Mihir's suggestion to change the ownership to the SERVERNAME$ for the objects within the CN=Microsoft Exchange System Objects container. I could not check the actual owner on any new folders as they will not appear in this container until they are
mail enabled. (Of which I cannot mail enable them)
On trying to change the owner from SYSTEM which is what it is on seemingly all objects, whilst I could select the Exchange server from the list, the setting would not take. (The SERVERNAME$ never appears in the list of possible owners after selecting it)
Instead I tested giving the Exchange Server (SERVERNAME$) full control permission on one of the objects/Public Folders. (Via ADSIEdit) This immediately allowed me to change as properties for the folder to include Send-As. (At last!!)
To fully resolve all permission issues, noting the Exchange server is a member of the Exchange Trusted Subsystem Group, I gave this group full control permissions on the CN=Microsoft Exchange System Objects folder and this resolved ALL permission issues
to include being able to create new folders, mail enable them etc.
No reboots/logoff etc were required, the settings are taken immediately. (Mileage may vary with replication)
Many thanks for getting me on the right track.

Problem with Exchange 2010 Public Folders after installing Exchange 2013 in my environment.

I currently have an Exchange 2010 server with all the roles installed. Before installing Exchange 2013, I was able to launch the Public Folder Management Console but now I get an error. When I installed Exchange 2013, I got an error saying I
had a instance of Exchange 2000 or Exchange 2003, but I didn't have any of these servers left. There was still something in AD referencing my old server. I went into ADSIedit and deleted an old administrative group. This deletion caused my access
to my public folders to get messed up. I followed this article, http://blog.bruteforcetech.com/archives/766, and I was able to gain access back in my outlook client but I still can't see the public folders in OWA. I also get this error when
trying to access either Default or System Public Folders. "Cannot complete the operation because there isn't an available public folder database on server 'ExchangeServer'. It was running the command 'get-publicfolder - getchildren -identity '\'
-server 'ExchangeServer' "
My Public Folder Database exists and is mounted. Any help is appreciated.

Hi Belinda,
Thank you for responding. Yes you do understand my problem correctly. One correction is that after deleting this entry in ADSIEdit, we couldn't access public folders at all either in Outlook or OWA. I followed these steps in the below article:
http://blog.bruteforcetech.com/archives/766
After following these steps and recreating the entry on FolderHieachies in ADSI edit, I was able to gain access to the public folders again through Outlook, but still can't see them in OWA and can't access them in Public Folder Management Console.
Here are the results to your requests:

Public folders not replicating Exchange 2010

Earlier this year I did a migration from a single 2003 Exchange server to a single Exchange 2010 server. I didn't notice until recently that my GAL isn't being updated in cached mode in Outlook 2010+ but is in OWA and with cached mode turned off. So,
I dug a little more, and also noticed that I also having errors when trying to go into Public Folder Management Console when I right click and and select update content on anything under Default Public Folders or System Public Folders I get an error about
no replica being found.

Is it possible to unsubscribe specific Public folders in Mail + Exchange?

We're using Mail connected to IMAP/Exchange accounts and have a lot of Public folders that we would like to unsubscribe to - since they update some 68.000+ mails which causes some speed conflicts. Its possible in Outlook(PC) and Thunderbird(Mac) but is it possible in Mail?

Thanks
Lets just hope these basic improvements will be included in the 3.0. - guess I'll have to start using Thunderbird for a while!

Shared resource Calendar in a mixed exchange environment

So another Exchange question. Mixed environment with Exchange 2013 HUB, CAS, and MBX servers in one location and Exchange 2007 HUB, CAS, and MBX server at another location. Currently all mail comes in through the 2013 server, but the outbound mail is handled by the server at their location ie: site A has the Exchange 2013 server handle the outbound, and site B has the Exchange 2007 server handle the outbound.We do not use puplic folders.I need to have a Shared Resource calendar that will be used\accessed by multiple users that are located on either the 2013 or the 2007 mailbox servers. This calendar should be resident if possible on the 2007 mailbox server as management does not intend to upgrade the Exchange 2007 server in the forseeable future, but there could be the potential for seperating into stand alone email servers for each...
This topic first appeared in the Spiceworks Community

Hi,
Have you configured federation trust between these domains?
With federated sharing in Exchange Server 2013, users can share information with recipients in external federated organizations. This includes sharing their free/busy (also known as calendar availability) information for scheduling purposes or, depending
on the nature of the business relationship, sharing more detailed calendar information.
I recommend you refer to the following articles:
Federation Procedures
Federation refers to the underlying trust infrastructure that supports
federated sharing, an easy method for users to share calendar information with recipients in other external federated organizations.
Hope this helps!
Thanks

Public Folders on multiple Exchange 2013 servers

Two companies (lets call them WestCoast Company and EastCoast Company) have merged. Each one has Ex2010 with PFs of local scope (the companies don't need access to each other's PFs). I want to move them to a single Exchange Organization with one Exchange
server in each office and possibly a 3rd Exchange in a data center. I am looking for the best/simplest solution for those legacy PFs. Questions:
- With Exchange 2010 I can only have one PF database so I will have to merge the PF structures. If the "master" PF DB sits in the data center I can choose which folders to replicate to each regional Exchange server (ie I can have only WestCoast
folders on the WestCoast Exchange and similar for East Coast). Are these statements correct?
With Exchange 2013:
- Can I have more than one PF trees (one per PF mailbox) or am I limited to a single PF hierarchy?
- If only one PF hierarchy, am I forced to have one location that holds all the content or can the content remain distributed in different locations?
- Can I have content (or PF mboxes) that only show up on some of the Exchange servers? (ie WestCost PFs will show up only on WestCoast Exchange)
- Do the PF limits (10,000 folders, 1 million items, etc) apply per PF mbox or for the whole thing?
Thanks

There is just one public folder hierarchy. You can assign sub-trees under the root to different mailbox databases, though, and through permissions you could restrict who can see each of them.
You can have public folder mailboxes mounted in different mailbox databases, with different databases mounted in different locations. So you could have the Europe folders in a mailbox in a mailbox database mounted on a European server, and the Americas
folders in a mailbox in a mailbox database mounted on an Americas server.
You can do that but only by grouping public folder mailboxes in mailbox databases that are mounted where you want them to be mounted. As stated before, you might be able to hide folders through permissions, not by where they are mounted.
Yes, the 10,000-folder limit applies to the organization. If you have more than that, wait until the limit is increased.

Exchange 2010 - Exchange 2013 permanent coexsistence to avoid migration of Public Folders

Hi Guys,
I was hoping to get some opinions/ advices regarding the case explained below.
The company I work for has a medium-sized Exchange 2010 infrastructure that consists of several geographically dispersed 2-node DAGs and corresponding CASArrays. It hosts about 1000 mailboxes in total and large public folder database that is replicated on
every mailbox server in the environment. All users are using Outlook 2010/2013.
There is a business drive to perform migration to Exchange 2013. However, migration of the Public Folders is not feasible because of the lack of multimaster replication, the complicated migration process and several other limitations in Ex2013 PFs.
To work around this issue while still performing the migration I am considering the following scenario:
Deploy Exchange 2013 servers in the organization
Migrate all mailboxes to Exchange 2013 servers
Don't ever start migration of Public Folders (leave one Exchange 2010 mailbox server in every location for hosting the Public Folder database)
Keep the coexistence permanently (with mailboxes on 2013 and public folders on 2010)
What do you think of this setup? Do you see any issues with such long-term coexistence?
Thanks.

Hi,
You can leave the public folders on Exchange 2010 if you can’t migrate them to Exchange 2013. Exchange 2013 users can access public folders on Exchange 2010, but Exchange 2010 users can’t access public folders on Exchange 2013.

Exchange 2013 Mailbox Using 2010 Public Folders

Firstly, we will not be migrating completely to Exchange 2013 public folders for quite a while. Our first Ex2013 server is in a small branch office and won't be appropriate to hose the PF's for the entire company. Our environment consists of
8 Ex2010 servers and now the one Ex2013. I setup a test mailbox on the 2013 server and it access a 2010 PF database on another server just fine. How is that server discovered, and can we specify which one it uses? I understand the way 2013
public folders are moving but is there a downside to leaving our configuration this way for a long period of time?

Yes, the procedure should be followed to move mailbox first. Once you have successfully moved all the mailbox to new exchange server, you can migrate public folder after that.
You can also checekout this thread related to public folder migration from exchange 2010 to 2013 :

Further, for a better convenience, you can also take a look at this application (http://www.exchangemailboxmigration.com/) which would be a good approach while migrating mailboxes and public folders
between two exchange server. It ensures about the data security and email contents during the completion of entire migration process.

Exchange 2013 / 2010 / 2007 - Public Folders

I have read that legacy public folders and 2013 public folders canot co-exist.
If I have legacy public folders A, B and C, does this mean...
that if I migrate folder A to 2013, i cannot maintain a replica on legacy systems, but folders B and C are still accessible
..or..
If I migrate folder A to 2013, I must migrate folders B and C also.
If I am need to import folder D, from an external Exchange 2013 installation, into my legacy public folder system, is it possible to migrate folder D out of the external 2130 environment into my legacy public folder environment? If so, is there any extra functionality
2013 PF has that the users will lose if the folders are down graded to legacy?
Thanks!
Tom

Hi,
User mailboxes on Exchange 2013 servers can connect to legacy public folders, but legacy Exchange mailboxes are unable to access the public folder hierarchy on Exchange 2013 server.
Exchange 2013 public folders and legacy public folders can’t exist in your Exchange organization simultaneously.
Before you migrate public folders, you need to migrate mailboxes to Exchange 2013 first.

Ignoring "Public Folders" when listing folders on an Exchange account?

hi-
i downloaded javamail 1.4.2 and ran the demo example "folderlist" against an exchange account i have using the "imap" protocol.
it listed all my folders correctly, including "Public Folders" and its subfolders.
i'd like to not list "Public Folders" though, and so was wondering if there is a programmatic way of ignoring this folder and any
other public folders.
when i run "folderlist" in verbose mode, i get for the "Public Folders":
Name: Public Folders
Full Name: Public Folders
URL: imap://exchange-user@exchange-host/Public Folders
Not Subscribed
Is Directory
IMAP Attributes:
\Noselect
is it appropriate to intrepret "\Noselect" as folders i don't want to include in my folder list?

Use the Store.get*Namespaces methods. You probably only want to list the personal namespaces.

Outlook Quick Steps with Categorize function - Exchange server public folders

Is it possible to categorize an e-mail with a Quick Step with the right step order?
I mean If want to do the following:
copy to a public folder
make it read
mark it complete
categorize it
It will categorize the e-mail first (like it has a higher priority) and both the actual e-mail and the copied one will be 'flagged' with the category.
Is it possible to modify the quick step that way to do the categorize function after the copy function, so the copied one will not be categorized, only the original one.
All the e-mails are in public folders, so I copy the e-mail from a public folder to another one. All the public folders are on Exchange servers.
Please advise.
Thank you!

Ah, no, you can't change that - the problem is that once it's move, the QS won't know which item is it, it adds the category first.
you can use something like this -
Sub MoveCopyMessage()
    Dim objNS As Outlook.NameSpace
    Dim objSourceFolder As Outlook.MAPIFolder
    Dim objDestFolder As Outlook.MAPIFolder
    Dim objItem As Outlook.MailItem
    Dim objCopy As Outlook.MailItem
    Set objNS = Application.GetNamespace("MAPI")
    Set objSourceFolder = objNS.Folders("Public Folders -
[email protected]").Folders("All Public Folders").Folders("New")
    Set objDestFolder = objNS.Folders("Public Folders -
[email protected]").Folders("All Public Folders").Folders("Old")
    Set objItem = Application.ActiveExplorer.Selection.Item(1)
' copy and move first
     Set objCopy = objItem.Copy
      objCopy.Move objDestFolder
' then do whatever to original
        With objItem
            .UnRead = False
            .MarkAsTask olMarkComplete
            .Categories = "This Category"
            .Save
        End With
    Set objSourceFolder = Nothing
    Set objDestFolder = Nothing
    Set objNS = Nothing
End Sub

Migrating Public Folders on Exchange Server 2007 SP1 to Exchange Online\Office 365

Hello,
Our company is looking to migrate from Exchange 2007 on premises to Exchange Online/Office 365. We have a number of public folders on our exchange server that function similarly to how the new shared mailboxes work in Exchange Online. That is to say that
we have many outside users (customers and wholesale dealers) emailing this public folder ([email protected]) and our end users are given permission to view and respond as themselves ([email protected]). I've been looking all over but haven't found a clean
way to migrate the current public folders directly into shared mailboxes. I'd just start from scratch, but we want to keep the records of the emails we've received at these public folders for customer support reasons. Can anyone help?

Hi psh8989,
According to your description, I know that you want to migrate public folder from Exchange 2007 to Office 365.
Since Office 365 is different from Exchange On-Premises, I suggest ask Office 365 Forum for help so that you can get more professional suggestions. For your convenience:
http://community.office365.com/en-us/default.aspx
However, I can also share some information for your reference : )
Based on my knowledge, Exchange supports moving your public folders to Office 365 and Exchange Online from Exchange 2007 SP3 RU10 or later. I notice that your Exchange server version is SP1, please upgrade to SP3 RU10 first and perform migration.
More detailed information to see:
Migrate legacy public folders to Office 365 and Exchange Online
