Yes, this is in event viewer:

[8/10/2017 8:56:56 AM] ERROR: 'Hosted Microsoft Exchange Server 2013' SetPublicFolderGeneralSettings
System.NullReferenceException: Object reference not set to an instance of an object.
at SolidCP.Providers.HostedSolution.Exchange2013.SetPublicFolderGeneralSettingsInternal(String organizationId, String folder, String newFolderName, Boolean hideFromAddressBook, ExchangeAccount[] accounts)
at SolidCP.Server.ExchangeServer.SetPublicFolderGeneralSettings(String organizationId, String folder, String newFolderName, Boolean hideFromAddressBook, ExchangeAccount[] accounts)

How about the exchange management log? does it hold any further information or warnings as to what fails to execute?

Aside this error, when i create a new customer and new hosted exchange hosting spacce. it will create a public folder with the wrong permissions (anonymous and mail enabled root folder) i than remove the public folder aswell as the public folder itself.

After that i rin the PFFix script provided in another topic and all is ok, no other users are bothered now.

Is it possible to fix this so that when creating a new customer the permissions will be set as it is in the Fix script?

Marco,

There is no info in the exchange management log.

Yes, i will add it to the fix list.

As it shouldn't be mail enabled or anything (it is an unusable pf root basically just there to segregate people to their org).
