Copy the following binaries from Windows 2k3 server (C:\Windows\System32\) to Windows Server 2008 (C:\Program Files\NTBackup\):

• ntbackup.exe
• ntmsapi.dll
• vssapi.dll

Then install the removable storage manager from server manager:

• Start Server Manager
• Click Features
• Click Add Features
• Select Removable Storage Manager
• Click Install

When NTBackup starts, if you see an error regarding removable storage, just ignore it and click “Do not show this again”.

I’m not sure, but it seems that it backup Exchange 2007 Databases too, for me it worked, but I didn’t tested restoring them.

SYMPTOMS

When you try to open a 2007 Microsoft Office system file attachment by using Microsoft Office Outlook Web Access, you may receive the following error message:

To open this attachment, you must save it to your disk, right-click the link, and then click Save.

This problem occurs if the following conditions are true:

RESOLUTION

To resolve this problem, add the 2007 Office system content types to Exchange so that the conversion process can recognize these content types. A content type is a string that has a file name extension associated with it. To add the string and the associated file name extension, use Exchange System Manager. To do this, follow these steps:

The Microsoft Exchange Information Store service stops responding (hangs) 24 to 36 hours after you enable an antivirus program that uses the Microsoft Virus Scanning Application Programming Interface (VSAPI) in Microsoft Exchange Server 2003. Sybari Antigen for Microsoft Exchange is an example of such a program.

Additionally, the Microsoft Exchange Information Store service may stop responding (hang) when you perform a backup of Exchange Server 2003.

Additionally, an event that resembles the following event may be logged in the Application log:

Event Type: Error
Event Source: Application Error
Event Category: (100)
Event ID: 1000
Description: Faulting application store.exe, version 6.5.xxxx.xx, faulting module exsmtp.dll, version 6.5.7638.1, fault address 0×000096f6.

1. Start the Exchange System Manager.
2. Click to expand the Recipients container.
3. Right-click All Address Lists, point to New, and then click Address List.

If you find objects that have the same e-mail address as the one you are trying to add, either change the e-mail address for this object or delete the address if it is longer needed.

Repeat the same process for public folders, contacts and groups, but use the following modifications:

1. In step 5, point to User, and then change the setting to Public Folder, to Contact, or to Group.
2. In step 6, click E-mail Address or Alias if the E-mail Address option is not available.
