On exchange server going on Public Folder snapin we got this error:
No existing 'PublicFolder' matches the following Identity: '\'. Make sure that you specified the correct 'PublicFolder' Identity and that you have the necessary permissions to view 'PublicFolder'.
The solution was got in this way
--------------------
Open ADSIEdit and connect to the Configuration context
Open Databases node
CN=Databases,CN=Exchange Administrative Group (FYDIBOHF23SxxxT),CN=Administrative Groups,CN=[ORG],CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=[DOMAIN],DC=[TLD]
Open the Properties of an Exchange 2010 database
View the distinguishedName property and copy the value to clipboard
Example: CN=E14MBXDB01,CN=Databases,CN=Exchange Administrative Group (FYDIBOHF23SxxxT),CN=Administrative Groups,CN=[ORG],CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=[DOMAIN],DC=[TLD]
Close the Properties window and open the Servers node
CN=Servers,CN=Exchange Administrative Group (FYDIBOHF23SxxxT),CN=Administrative Groups,CN=[ORG],CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=[DOMAIN],DC=[TLD]

CN=DB-PBLCF03,CN=Databases,CN=Exchange Administrative Group (FYDIBOHF23SXXXT),CN=Administrative Groups,CN=PIPPO,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=pippo,DC=com
Expand the first Exchange 2010 server and open the Properties of the Microsoft System Attendant node
Ensure that the view is not filtered to Show only attributes that have values
Edit the homeMDB attribute and paste the distinguished name of the mailbox database copied in step 4
Apply the changes and close the properties window
Open the Properties windows of the Microsoft MTA of the same Exchange
View the distinguishedName property and copy the value to clipboard
Example: CN=Microsoft MTA,CN=E14MBXSRV01,CN=Servers,CN=Exchange Administrative Group (FYDIBOHF23XXXLT),CN=Administrative Groups,CN=[ORG],CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=[DOMAIN],DC=[TLD]
sotto pfex1 Microsoft MTA
CN=Microsoft MTA,CN=XXXXX-EX,CN=Servers,CN=Exchange Administrative Group (FYDIBOHF23SXXXT),CN=Administrative Groups,CN=PIPPO,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=PIPPO,DC=com
Open the properties of the Microsoft System Attendant node for a second modification
Ensure that the view is not filtered to Show only attributes that have values
Edit the homeMTA attribute and paste the distinguished name of the mailbox database copied in step 10
Apply the changes and close the properties window
Repeat steps 4 to 13 for each Exchange 2010 server in your environment.
- Wait for Active Directory replication and retry to access the public folders using Get-PublicFolder in an Exchange Server 2007 Management Shell.
- It might be required to restart the Exchange 2007 Information Store and System Attendant service of the Exchange 2007 server in question
Use an administrative PowerShell
