Exchange 2010 Free/Busy Error

Posted on 2010-11-23
Last Modified: 2012-05-10

I am completing a migration from Exchange 2003 to 2010

Every 15 minutes I am getting error ID 14029 in my Exchange 2010 Application Log.

Couldn't find an Exchange 2010 or later public folder server with a replica for the free/busy folder: EX:/O=domain/OU=FIRST ADMINISTRATIVE GROUP.

I did some research and it appears the replica for this Free/Busy information should exist on my 2010 server.  I moved all replicas from 2003, checked the public folders were empty and moved the public folder higherarchy to Exchange 2010.  I also allowed 2 days for the public folders to replicate.  I have since uninstalled Exchange 2003

When I run the command:

Get-PublicFolder "\non_ipm_subtree\schedule+ free busy" -recurse |fl name,*rep*

I receive output of:

Name                           : SCHEDULE+ FREE BUSY
LocalReplicaAgeLimit           :
Replicas                       : {}
ReplicationSchedule            : {}
UseDatabaseReplicationSchedule : True

Name                           : EX:/o=domain/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)
LocalReplicaAgeLimit           :
Replicas                       : {Public Folder Database 2112963168}
ReplicationSchedule            : {}
UseDatabaseReplicationSchedule : True

Name                           : EX:/o=domain/ou=First Administrative Group
LocalReplicaAgeLimit           :
Replicas                       : {Public Folder Database 2112963168}
ReplicationSchedule            : {}
UseDatabaseReplicationSchedule : True

It appears the replica exists but I am still receiving the errors.  

I ran the following script on my 2010 server but still was unable to solve the problem:

AddReplicaToPFRecursive.ps1 -TopPublicFolder "\Non_IPM_SubTree\schedule+ free busy" -ServerToAdd Ex10-1

I found an article at Technet and followed it as best I could but still to no avail. 

Any help would be most appreciated!

Whather Forms authentication on the EWS VDir in IIS is enabled or disabled. if its enable disable it and restart the IIS. Converted the address lists to 2010 and reset the OAB directory, enabled web based distribution, check and rebuild your autodiscover service. Hope this will resolve the issue.

Are you planning to decomission your old exchange 2003 ?

Are you planning on having your public folders left on the exchange 2010 server ?

In exchange 2003 free busy is stored within public folders, with exchange 2010 free busy are NOT stored within public folders but within the users mailbox.

If these errors are exactly between 15 minutes intervalls, could just be pub folder sync issue due to the free busy (just a guess).

If it is not always 15 minutes, this could inditcate that a user who is on exchange 2003 is trying to retrieve free busy information of a user who have been migrated to exchange 2010. (hence the difference of where users free busy are stored depending on the exchange server version). Remember that there are SYNC delays, always, when you migrate a user from ex2003 to ex2010 so even though everything is working, the information store needs to update itself on bouth exchange server 2k3 and 2k10, as well as exchange 2003 recipient update service needs to run, ( this service is no longer available in exchange 2010, but instead you can run "update-recipient -identity" from EMS)

Authentication on the EWS virtual directory was disabled before moving over the PF replicas from 2003 to 2010.  It's the only way I was able to do so.  The address lists have already been converted to Exchange 2010 format and the OAB is being replicated by Exchange 2010.

What do I need to do to enable Web based distribution and how do I rebuild the autodiscover service.  Even just links of general help would be appreciated,


Exchange 2003 is already decomissioned, it's completely uninstalled using Add/Remove programs and RUS has been removed using ADSIEdit.  There are no users left on Exchange 2003.

The Public Folder Store mentioned in my original post is on the Exchange 2010 server.  We needed to use it since one of our applications requires it to distribute forms.

Lastly, the error occurs every 15 minutes, which is what our PF replication time is set to.

I haven't had a chance to make the changes yet.  I needed to perform some additional server maintenance and testing which will be done this weekend.  Once the changes are made I'll post some updates.  Thanks for your help and following up!

Thanks to both of you for your help.  The issue was resolved with the additional maintenace this weekend.  

The issue ended up being in the Alias name of the public folder replica.  When Exchange 2003 copied over the replica for First Administrative Group, it put space in the alias name.  Exchange 2010 wasn't able to work with this.  After correcting the alias name I needed to restart the server to remount the PF database and correct the error.  I am no longer getting the free/busy errors.

Since you both helped, I figured it would be fair to award points to both of you.  Thanks very much!

The solution ended up being unrelated to the recommendations and rather to the Alias name of the public folder database in Exchange 2010.
