1.1. Restoring Favorites in Outlook

Occasionally, when you launch Outlook, the Favorites you have created may disappear.  Why does this happen?  Well, your guess is as good as mine and may be more than Microsoft knows.  But how do you fix it?  Here's how:

• Click Start
• Select Run (if Run is not available, then it will need to be added in the Properties for your Task Bar)
• Type: "C:\Program Files\Microsoft Office\Office14\outlook.exe" /resetnavpane
  ***(check the location of your outlook.exe first)

That's it.

2.1. How to configure the size limit for both (.pst) and (.ost) files in Outlook 2007 and in Outlook 2003

How to configure the size limit for both (.pst) and (.ost) files in Outlook 2007 and in Outlook 2003

Microsoft Office Outlook 2007 and Microsoft Office Outlook 2003 supports both American National Standards Institute (ANSI) and UNICODE personal folders (.pst) and offline folder (.ost) files. This article describes how to use the following four registry entries to limit the size of both the .pst and the .ost files:

• The MaxFileSize registry entry
• The WarnFileSize registry entry
• The MaxLargeFileSize registry entry
• The WarnLargeFileSize registry entry

Note The WarnLargeFileSize and WarnFileSize registry entries do not enable Outlook to warn you before the file size limit is reached.Back to the top

The MaxFileSize registry entry

The MaxFileSize registry entry determines the absolute maximum size that both the .pst and the .ost files can grow to. After this maximum size is reached, Outlook does not permit the size of the file to grow beyond this size. Back to the top

The WarnFileSize registry entry

The WarnFileSize registry entry determines the maximum data that both the .pst and the .ost files can have. After this maximum data is reached, neither the .pst nor the .ost files are permitted to add any more data. However, the size of the physical file may still increase because of internal processes.

In the following table, the MaxLargeFileSize registry entry and the WarnLargeFileSize registry entry refer to a UNICODE formatted (new Large format) file, and the MaxFileSize registry entry and the WarnFileSize registry entry refer to an ANSI formatted (an earlier Microsoft Outlook format) file. The UNICODE values are set in megabyte (MB) increments, while the ANSI values are set in byte increments.Collapse this tableExpand this table

Name	Type	Valid Data Range	Default
MaxLargeFileSize	REG_DWORD	0x00000001 - 0x00005000	0x00005000 20,480 (20 GB)
WarnLargeFileSize	REG_DWORD	0x00000000 - 0x00005000	0x00004C00 19,456 (19 GB)
MaxFileSize	REG_DWORD	0x001F4400 - 0x7C004400	0x7BB04400 2,075,149,312 (1.933 GB)
WarnFileSize	REG_DWORD	0x00042400 - 0x7C004400	0x74404400 1,950,368,768 (1.816 GB)

The policy location for the registry entries is located in the following path in Registry Editor.

Outlook 2007

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Outlook\PST The user preference location for the registry entries is located in the following path in Registry Editor:HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\PST

Outlook 2003

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Outlook\PST The user preference location for the registry entries is located in the following path in Registry Editor:HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\PST

 

2.2. Open an Office 2010 and 2007 documents in an earlier version of Office

The 200/2010 Microsoft Office system introduces a new file format that is based on XML. It is called Open XML Formats and applies to Microsoft Office Word 2007/2010, Microsoft Office Excel 2007/2010, and Microsoft Office PowerPoint 2007/2010. This article summarizes key benefits of the new format, describes what the new file name extensions are, and discusses how you can share the 2007/2010 Office release files with people who are using earlier versions of Office.

If you send one of these files to someone with an earlier version of, let's say, Word, then they will need the following on installed on their computer from Microsoft.  It's a free utility that allows opening these new document formats on an older verion.
