Exchange 2003 to 2010 Upgrade, Error with Free/Busy folder replicas

I’ve been migrating some of our slower customers away from Exchange 2003 recently, and I ran into a issue that took me 3 days to figure out. I was getting the following erorr on the 2010 Server: Couldn't find an Exchange 2010 or later public folder server with a replica for the free/busy folder: EX:/O=FIRST ORGANIZATION/OU=FIRST ADMINISTRATIVE GROUP despite successfully running the AddReplicaToPFRecursive.ps1 on the \NON_IPM_SUBTREE\ Top Public Folder. On the 2003 server, all folders, including the Free/Busy folders displayed two replicas, one for 2003 and one for 2010.

I eventually moved all replicas from the 2003 server and removed the PF database hoping that it would force any replicas that remained and perhaps weren’t being displayed properly over to the 2010 server, and I was prompted to do just that, but still I continued to receive the error stated above.

The reason that I’m posting this is not that it’s a new issue, it seems like it’s a pretty common problem, but rather the hard time I had finding the correct resolution online. Perhaps my search terms were off, but in case The way to solve this is as follows:

On the 2010 server, run the following commands:

1) Set-PublicFolder -Replicas '2010 Public Folder Database' -Identity '\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY\EX:/o=First Organization/ou=First Administrative Group'

and then verify it worked:

2) Get-publicfolder -recurse '\Non_IPM_SubTree\SCHEDULE+ FREE BUSY\EX:/o=First Organization/ou=First Administrative Group' |fl

3) restart the “Microsoft Exchange Mailbox Assistants” service

Outlook 2010/2007 stuck in disconnected state for one user

Ran into a problem today with an Outlook 2010 client that would not leave the “disconnected” state. I restarted the computer, verified the mailbox was still active in Exchange 2003, and verified that this problem was not effecting other users, even ones on the same PC. I tried to create a new outlook profile, but during the setup I kept getting the same error:

“Microsoft Exchange Server reported error: The server is
not available. Contact your administrator if this condition persists”

It appears that just this one user cannot connect to exchange, the way that we solved this problem was by increasing the maximum number of connections that each user can make to Exchange 2003. Follow these steps on your Exchange server:

  1. Open Regedit
  2. Navigate to HKLM\CurrentControlSet\Services\MicrosoftExchangeIS\ParametersSystem
  3. Create a new DWORD called “Maximum Allowed Sessions Per User” and set it to decimal 64.
  4. Restart the “Microsoft Exchange Information Store” service
  5. Attempt to reconnect with the user’s outlook.

Hopefully this took care of your problem user.
