Event 9399: OALGen is configured to generate version 4 OAB files for offline address book ‚\Default Offline Address List‘ and publish it to public folders, but there is no public folder server available. OAB version 4 will be generated but will not be published to a public folder at this time. Please ensure that a public folder server with a replica of the Offline Address Book system folder is online and mounted, or disable publishing OAB version 4 to public folders.

The Generation Server for the Offline Address Book must have at least one online Mailboxdatabase. In a DAG you should never locate it on a node which will hold the passive Databases – it will result in the Error above. Just move to the Active Server ( EMC: Microsoft Exchange – Microsoft Exchange On-Premises – organization Configuration – Mailbox – Offline Address Book )

Get-PublicFolderStatistics -id „\Samplefolder“ | fl results in:

Couldn’t find public folder „\Samplefolder“ on server „server.local“.

+ CategoryInfo : InvalidData: (\Samplefolder:PublicFolderIdParameter) [Get-PublicFolderStatistics], InvalidOperationException

+ FullyQualifiedErrorId : 762BCDDB,Microsoft.Exchange.Management.MapiTasks.GetPublicFolderStatistics

Solution:

Get-PublicFolderStatistics -id „\Samplefolder“ -resultsize unlimited | fl

This seems to be a Bug 🙂

If you like to Delegate Server and Recipient Management to a Site which has it’s own Exchange Server:

# create a management scope to restrict access to the server only
New-ManagementScope -Name "DELEGATED Servers" -ServerList SERVER1

#create a DELEGATED role group for server management
$RGS = Get-RoleGroup "Server Management"
New-RoleGroup "DELEGATED Server Management" -Roles $RGS.Roles -CustomConfigWriteScope "DELEGATED Servers"

Add-RoleGroupMember "DELEGATED Server Management" -Member "delegated-exchange-g"

#create a DELEGATED role group for recipient management
$RGR = Get-RoleGroup "Recipient Management"

Restart MS Exchange Search Indexer and remove old Paths

ake a look at Organization Configuration – Hub Transport – Accepted Domains in Exchange Management Console. Change the type of the Domain in the error message to „Authoritative“…

The domain in the Error message is a sub domain, created after you have installed your first exchange 2007 server in your exchange 2003 environment.

While removing Exchaneg 2003 you get : „One ore more users currently use a mailbox store on this server – the userser muste be moved…“

1. Run Active Directory Users and Computers.
2. Right-click your domain towards the top of the left-hand pane and choose Find from the context menu.
3. In the Find Users, Contacts, and Groups window, click the Advanced tab.
4. Click the Field button and then choose User. From the list of attributes displayed, choose Exchange Home Server.
5. Set the Condition field to Ends With and then type the name of the old Exchange server into the Value field.
6. Click Add to add this condition to the Condition List.
7. Click the Find Now button and you should be presented with a list of objects that still have Exchange attributes. You will need to clear these before you can remove the server. Note that you don’t need to worry about system mailboxes.

Goto the properties of the Mailbox Store – Limits and change „Keep deleted mailboxes“ to 0

Then right click on the Stores Mailbox folder  and choose „Run Cleanup Agent“
