While installing Microsoft Exchange 2010 SP1, the setup might fail with the following error

Export and Import mailboxes in Exchange 2010 SP1
Ever since Exchange 5.5 I have been longing for an easy way to import/export mailboxes to and from PST. I have to admit that Exmerge was a pretty decent tool back then, however, although it did work, I was very disappointed by the requirements of import-mailbox export-mailbox on Exchange 2007, and I prefer to forget the frustration of using these commands with Exchange 2010 RTM.
I can happily say that all my problems are now quickly forgotten after the release of Exchange 2010 SP1 and the new commands New-MailboxImportRequest and New-MailboxExportRequest.
Prerequisites and permissions considerations
I am happy to say that installing Outlook on the server is no longer a requirement to export/import mailboxes and this, for me, was great news!
If you rush things and directly try to run New-MailboxImportRequest cmdlet it will fail with the following error, this is because, by default, no one is assigned the permission to Import and Export mailboxes.
“The term 'New-MailboxImportRequest' is not recognized as the name of a cmdlet”
Disable & Enable Organizations in Exchange 2010 SP1 multi-tenant
One thing I have noticed while working with Exchange 2010 SP1 installed in hosting (or multi-tenant) mode is the lack of the possibility to disable/enable a tenant organization.
There is a lot of scenarios when disabling a tenant organization can be very handy and useful. For example if a client didn't pay, you might want to suspend his account without deleting the whole organization and making him lose data.
I have recently developed my own scripts to disable and enable, or suspend and resume, a specific organization for a client of mine and never thought of sharing them until yesterday when this same question popped up on the technet forum and I thought that they might be helpful for some of you so here they are.
Disclaimer
I need to start with a disclaimer, I have built these script for my own use so they are not polished and might be lacking a lot of features and surely have some bugs. Although I am ready to work on them and enhance them if they find interest and feedback I am not to be held responsible for any damage they might cause to your environment. So, in short,

Receiving email
It is well known that if your exchange 2007/2010 is internet facing you will need to add "Anonymous" to the permission groups of the "Default Receive Connector" on your Hub transport server. Exchange 2010 running in hosted mode is no exception however there is no Exchange Management Console anymore to do this change so we will need to do it through powershell by running the following command. Of course don't forget to replace "Exchange" by your Hub server name.

A look at Service Plans
Before doing a jump start and create an organization we need to take a look at some files located on your CAS server called Service Plans.
Service plans are located by default in "C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\ServicePlans" of your CAS server and they define the different services your hosted organization provides to its customer.
