There is sometimes the need to permanently delete disconnected mailboxes. For example, if you moved mailboxes between databases, the previous database will still hold a copy of the moved mailboxes (by default for 30 days). If you’re tight on disk space, you might want to delete the disconnected mailboxes manually.
Note: Your Exchange database file size will not decrease right-aways, however, the Exchange Mailbox Server(s) will immediately have free space inside the .edb file for new emails.
Step 1: Retrieve List of Disconnected Mailboxes
Get-MailboxDatabase | Get-MailboxStatistics | where {$_.DisconnectReason -eq “SoftDeleted”} | Select DisplayName,ServerName,Database,ItemCount
Step 2a: Permanently Delete an Individual Disconnected Mailbox
Remove-StoreMailbox -Database (Database) -Identity (useralias) -MailboxState SoftDeleted
Step 2b: Permanently Delete all Disconnected Mailboxes across all Databases (enter below commands into a .ps1 file before executing)
$var1 = Get-MailboxDatabase | Get-MailboxStatistics | where {$_.DisconnectReason -eq “SoftDeleted”}
$var1 | foreach {Remove-StoreMailbox -Database $_.database -Identity $_.mailboxguid -MailboxState SoftDeleted}

This Exchange Management Shell Script returns the available free space (whitespace) within your mailbox databases. This may by useful to know when you purged disconnected mailboxes.
Get-MailboxDatabase -status | fl Name,AvailableNewMailboxSpace
The result will look similar to this.
Name : Mailbox Database 1
AvailableNewMailboxSpace : 14.41 MB (15,106,048 bytes)Name : Mailbox Database 2
AvailableNewMailboxSpace : 5.251 GB (5,638,553,600 bytes)Name : Mailbox Database 3
AvailableNewMailboxSpace : 142.3 MB (149,258,240 bytes)

Here an Exchange Management Shell script that displays the user count per database.
Step 1: Create a new text file in C:Scripts named “Get-MailboxCountPerDatabase.ps1” and paste the code below into the text file.
write-host -fore yellow “This script will get each mailboxdatabase and the current user count ”
foreach($name in get-mailboxdatabase)
{
$count=(get-mailbox -database $name).count
write-host $count -nonewline
write-host ” mailboxes in $name”
}
write-host -fore yellow “The system has a total mailboxes of “$user=(get-mailbox –resultsize unlimited).count
write-host -fore red $user

Problem:
You have downloaded and installed the free ESXi 4.1 installable iso file, then installed it on your server. Later you downloaded and installed the vSphere Client 4.1. When you login to ESXi 4.1 using the vSphere Client, it displays a warning that your evaluation license will expire in 60 days. You can’t find any way to install/assign the license key nor on the server or the vSphere Client.

Here’s the scenario. A friend of mine gave me his old disk drive to have it copied to a new drive. The old drive had permissions set on files and folders. Some of the files were not accessible, I was getting “Access Denied”.
I tried to right-click/properties on the folders that were not accessible and changed their owner and changed permissions but some folders were still inaccessible not matter what I did.
After some research, it turned out the tool “cacls” that allows one to display or change ACLs (access control lists) can help to reset ACLs.
In Windows 7 it is called “icalcs”. To reset files permissions simply do this:
That is it!
After that, the files permissions were reset and I could access them just fine.
icacls is a handy tool to change permissions of files en masse.
