Exchange 2010 Free+Busy Errors, Event ID 14031

cmackles used Ask the Experts™
Our organization is using Exchange 2010, migrated from Exchange 2003. Everything *appeared* to have migrated over with the exception of the public folder replicas. We have about half of our clients using Outlook 2007 and the other half using Outlook 2003. Events keep getting logged to the mail server indicating our Outlook 2003 users do not have a freebusy public folder.

The Exchange 2003 server has been fully decommissioned and is permanently offline. There is no way for us to bring it back up.

Trying to create replicas in the Public Folder Management Console doesn't work (understandably) since the old mail server does not exist and cannot be connected to. Is there a way to clear up this issue?

Server mail1 has Hub Transport, CAS, and Mailbox roles. Also has public folders, OAB generation, and is on a member server, not a domain controller. It is running on 2008 R2 Enterprise, Exchange version is 2010 Enterprise.

I was told by one of my engineers that public folders had "stopped working" on the old mail server a long time ago, but never mentioned it until recently. I'm not sure what was meant by that, but everything seems to have come over to Exchange 2010 just fine. I believe I shouldn't ignore these errors since one or more of them may try to use the Out Of Office assistant and get slapped with an error message, so I'd like to get rid of this problem before it becomes a problem.

- Right click on the Exchange 2010 Mailbox Database under Org Config/Mailbox. On the Client Settings tab, it should be pointed to the correct public folder server\storage group\database.
Migration isnt done properly,Change the legacyexchangedn value of the users who are migrated using admodify in bulk, try for one user and then for rest:
Change the LegacyExchangeDN attribute of users from the old administrative group to point to one of the remaining administrative groups. To do this, follow these steps:

a.Download the Admodify.exe tool from, and then extract the contents of the .zip file to a folder.

b.Double-click Admodify.exe. If you are prompted to run the program, click Run.

c.In the ADModify.NET dialog box, click Modify Attributes.

d.Under Domain List, click the domain entry that corresponds to the domain in which the affected Exchange server is located. For example, click DC=corp,DC=example,DC=com.

e.Under Domain Controller List, click the fully qualified domain name of the domain controller that hosts the affected Exchange users. For example, click

f.Click to clear the following check boxes:



Public Folders

Show Containers Only

Do not clear the Users check box.  
Click the green arrow button that is beside Domain Controller List.

a.Under Domain Tree List, expand the domain object that is displayed.

b.Click the container in which the affected users are located. For example, click Users.

c.Click Add to List, click Select All, and then click Next.

d.Click the Custom tab, and then click to select the Make a customized attribute modification check box.

e.In the Attribute Name box, type LegacyExchangeDN.

f.In the Attribute Value box, type an entry that corresponds to the string value that is appropriate for your organization. You must replace the last part of the string value with a variable that is appropriate for all users. For example, type a value that resembles the following:
/o=First Organization/ou=Exchange Administrative Group (Internal_Name)/cn=Recipients/cn=%'Alias'
In this example, the following information applies to the cn=%'Alias' part of the string value:

a.Click Go.

That info is pulled from

and now to avoide any mailflow issue add x500 address on all the users which were migrated, no need to do for the  mailboxes that were created in e2k10. follow below article.

or do you still have your legacy exchange adminstrative group or it is deleted check through Adsiedit, if it is there then let me know else follwo above things.


shreedhar: The mailbox store is currently pointing to the correct public folder database and the default OAB is correct as well.

Narayan_singh: I looked in ADSI Edit and found the legacy admin group under Configuration context. It is no longer in use as far as I know. All mail is being routed by Exchange 2010.

ok cool.go to property of the e2k10 admin group and copy the value from sitefolderserver attribute.
go to the property of the legayadmin group nad open same attribute "sitefolderserver" and u will have old entry there paste the value there which u copied above....
restart info store and now do
get-publicfolder -identity "\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY" -recurse | fl identity, Replicas

and see if there is a folder for legacyadmin group and current PF store should be set as replica..
you could see this even from management console


Narayan_singh: Will try that tonight. We have scheduled an outage time this evening so I will be doing that then. Will let you know what happens.


This did it. No more of those events being logged and everything is working as it should. Thanks a million!
our exchange organization upgrated from exchange 2007.
under the configuration in adsi.edit there are two Administrative Groups
1- CN=Exchange Administrative Group (FYDIBOHF23SPDLT)
2- CN=First Administrative Group
but both of them have same siteFolderServer attribute with same syntax
Which is our Legacy group.?
and we are getting Event 4030 MSExchange Availability Error:
"Process Microsoft.Exchange.InfoWorker.Common.Delayed`1[System.String]: Unable to find any replicas for free/busy folder EX:/o=Our Exc Organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)."
at the Public Folder Management Console I can't add Public Folder on the Replication tab for "SCHEDULE+ FREE BUSY" folder. it is giving security error (is'nt allowed)
how can i fix this.?

I receive this error when I try the following link
