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

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.

During Installation you receive the “Setup Failed due to insufficient permissions.  Please make sure that the current User has local administrator permissions.  Error: The source was not found, but some or all event logs could not be searched. Inaccessible logs: Security.” error.

The reason is “UAC – User Account Control in Server 2008” You must turn it off from control panel or run setup.exe as administrator.

You probably are familiar with the issue.
You created multiple distribution groups , over the years and now you don’t know if they are in use.

Usualy company uses half of available distribution lists.

So how you can trace it ?

In exchange 2007 follow this.

Get-MessageTrackingLog -Start 1/1/2009 -EventID Expand | ft Timestamp,RelatedRecipientAddress -Autosize

You get back something like this:The output shows when specific distribution group received last message.

Timestamp RelatedRecipientAddress
——— ———————–
1/11/2008 2:06:21 PM DG-Doctors@domainname.com

Now we need to check how many emails each group has

Get-MessageTrackingLog -Start 1/1/2009 -EventId Expand | group-object RelatedRecipientAddress | ft Name,Count -Autosize

You’ll receive something similar to this

Name Count
—- —–
Doctors@domainname.com 347

As you probably know Microsoft releases set of DST patches for their systems every year at December .
To avoid DST calendar issues  make sure to install/deploy the following updates to entire organization.

• Microsoft Windows Server and Windows XP/Vista Clients : KB 955839
• Microsoft Exchange Server and outlook 2000/2003/2007 Clients:KB 941018 make sure to read MS DST Blog

The country that was skipped in MS  Day Light Saving update are Argentina/Brazil and Chile.

• Daylight saving time begins: October 19th, 2008
• Daylight saving period ends: March 15th, 2009

Since the new dates published by the federal are different from what was defined in the initial years, Windows-based computers am able to not correctly interpret the time such a is related to the transition to daylight saving time.

General recommendations

• There is no hotfix to be had at this time to update MS Operating Systems with the 2008-2009 DST dates for Argentina.
• Please note that if you adjust the machine’s clock manually, you may have adverse effects on your environment.
• Before applying the changes on Windows Operating Systems to reflect the change in Daylight Saving Time in Argentina, be aware of possible issues that am able to affect Microsoft Office Outlook and Exchange Server.
• Contact Microsoft Support prior to any modification if you are unsure about the steps to emulate in condition to be prepared for the Daylight Saving Time change in Argentina.

Impacts for Outlook clients and Exchange

• For the year 2008-2009, customers paying for the ‘(GMT -3:00) Buenos Aires’ minute zone have a delta period at the start on of the DST as follows:
  Delta-Argentina-BuenosAires
  From Sunday, October 19th, 2008 to Saturday, December 28th, 2008.
• And for customers using the ‘(GMT -3:00) Georgetown’ time zone have a delta range that comprehends the whole DST period:
  Delta-Argentina-GeorgeTown
  From Sunday, October 19th, 2008 to Saturday, December 28th, 2008

As result appointments may be off 1 hour. This may happen for both recurring and single-instance appointments.
The appointments created in the wake of the DST dates have been updated on the operating system will have the correct time.
