During migration from Exchange 2003 to 2007 we had the problem with Outlook 2007 client free busy response was slow , about 10 seconds to load .

To fix it .
Open registry editor on your Desktop(where outlook is installed)

Navigate to the following path : HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Options\Calendar
Create new DWORD value named UseLegacyFB and set value to 1

Note:
0 or not set will use default outlook settings
1 will use Public Folder based Free/Busy information

Read KB958934 to get more information.

If you try to move DB on Exchange 2007 CCR you will find that the option is grayed out. And you can’t use Exchange Management Console.

You can move your DB’s via powershel, see examples bellow.

Suspend-StorageGroupCopy -Identity mailserver\SG01-SG

Dismount-Database -Identity mailserver\SG01-SG\DB01

Move-DatabasePath -Identity mailserver\SG01-SG\DB01 -EdbFilePath "E:\DB\DB01.edb" -ConfigurationOnly

Mount-Database -Identity mailserver\SG01-SG\DB01

Resume-StorageGroupCopy -Identity mailserver\SG01-SG

Snap Manager for Exchange version 4.0 jobs filed and in Event viewer you see Event ID:1000

It happens after applying the .NET 3.5SP1 family updates.Basically the update breaks Snap Manger

SnapManager fails with the following error:

Faulting application SMESrvr.exe, version 4.0.0.1283, faulting module mscorwks.dll, version 2.0.50727.3082, fault address 0×0025a746
Faulting application SMESrvr.exe, version 4.0.0.1283, faulting module mscorwks.dll, version 2.0.50727.3053, fault address 0×0025a746
Version number in event log:
Event ID 1000 in application event log: Faulting application SMESrvr.exe, version 4.0.0.1273, faulting module mscorwks.dll, version 2.0.50727.3082, fault address 0×0025a746

To solve it you have 2 solutions .

The first is to Upgrade to Snap Manager version 5.
The update doesn’t require reboot and this is my preferred method

The second is to downgrade your .NET 3.5SP1
Remove .NET 2.0SP2 from your machine and re-install to 2.0SP1.
To roll back the installation:
1.    Uninstall .NET 3.5SP1, 3.0SP1 and 2.0SP2 in the order as listed. Windows will not allow to uninstal if you don’t remove previous versions first
2.    Reinstall .NET 3.5SP1, this will include all previous version of the .NET framework at the latest revision level at time the package was bundled.
3.    Check mscorwks.dll to ensure the version has changed from 2.0.50727.3082 or 2.0.50727.3053;
4.    Rollback of .NET may require a reboot.

In Vista Windows 2008  or Windows 7 when  you right-click the network icon in the navigation area, but it does not take you directly to the Network Connections properties as we are used to in Windows XP 2000 or 2003 .
You can access Network Connections management menu by running ncpa.cpl from run menu or you can create a shortcut that will access those menu by key combination.

To create ncpa.cpl shortcut

• Right-click on the desktop
• Click: New>Shortcut
• Type the location of the item: ncpa.cpl 
  
• Choose a suitable name, e.g. ‘Network Connection’
   
• Right-click on the newly created shortcut
• Select Properties and seek the dialog box called Shortcut Key.
      Simply over-type ‘None’ with the combination that suits you, for example:
      Ctrl +Alt +N.  Start by holding the Ctrl key, ‘None’ should change.
   
• Now by pressing on Ctrl +Alt+N Network Connection Properties will Open.

Creating shortcuts using control panel applets (CPL files) can be be very useful.
Here is a list of common CPL files which can be used.
