Some useful Exchange Management Shell commands:

For all mailboxes on the server, set policy:
get-mailbox -server servername | set-mailbox -managedfoldermailboxpolicy 'policyname'

For all mailboxes, set mailbox policy:
get-mailbox -resultsize 5000 | set-mailbox -managedfoldermailboxpolicy policyname'

Move mailbox to a specific mail database

Count the mailboxes per storage grp/mail db
get-mailbox -server servername | group-object -property:database | sort-object -property:count

Move one mailboxfrom command line

Frequently you need to uninstall some software which is causing your system grief, but you can’t uninstall it in safe mode. Follow these instructions to enable the windows installer.

You simply need to create a registry entry the type of safe mode you want to use:

Safe Mode:
REG ADD “HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\ MSIServer”/VE/T REG_SZ /F/D”Service”

Safe Mode with Network:
REG ADD “HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\ MSIServer”/VE/T REG_SZ/F/D”Service”

Then start the Windows Installer service by typing “net start msiserver”.

This is a little story about four people named Everybody, Somebody, Anybody, and Nobody.

There was an important job to be done and Everybody was sure that Somebody would do it.

Anybody could have done it, but Nobody did it.

Somebody got angry about that because it was Everybody’s job.

Everybody thought that Anybody could do it, but Nobody realized that Everybody wouldn’t do it.

It ended up that Everybody blamed Somebody when Nobody did what Anybody could have done.

Moral of the story: make sure you identify WHO is responsible for everything you request. Don’t send an email addressed to a group of people and expect that any one of those people will just assume responsibility. Just because it’s important to you, doesn’t mean it’s important to the people you sent your email to. Focus your attention on an individual, and confirm their acceptance of responsibility.

Have a machine you want to connect to, but remote desktop isn’t enabled? As long as you have administrator access to that machine you can enable remote desktop very easily from another machine on the same network. Just use Regedit and connect to the remote machine’s registry and make one change.

Change Dword value: hklm/ system/ currentcontrolset/ control/ terminal server/ fDenyTSConnections from 1 to 0

Of course you can do this from the command line if you have PSExec:
psexec \\computername/ipip reg add “hklm\system\currentcontrolset\control\terminal server” /f /v fDenyTSConnections /t REG_DWORD /d 0

You should also be able to do this with WMI:
wmic /node:”FQDN Name” RDTOGGLE WHERE ServerName=”HostName” CALL SetAllowTSConnections 1

For XP you may need to do this instead:
wmic /node:”HOSTNAME” path win32_terminalservicesetting where servername=”HOSTNAME” call SetAllowTSConnections 1

You can connect to the “console 0″ session from a command line:
mstsc /v:x.x.x.x /console – for rdp clients before v5
mstsc /v:x.x.x.x /admin – for rdp clients v6 or higher

Exchange memory management follows the “Law of Two Year Olds”, which goes something like this:

If it’s in my hands, it’s mine.
If I like it, it’s mine.
If it looks like mine, it’s mine.
If I saw it first, it’s mine.
If I can take it away from you, it’s mine.
If I had it a while ago, it’s still mine.
If I’m doing or building something, all the pieces are mine.
If you put something down within my reach, it’s mine.
If it’s mine, it must never appear to be yours in any way.
If it’s broken, I didn’t do it.
If you have one, where’s mine?

Pretty much sums it up, doesn’t it?
