Items are missing from my local file.
I have turned on automatic synchronization, but my folders are not being synchronized.
Even though you may have specified automatic synchronization for your offline folders while you are online, for performance reasons, this will not occur if Microsoft Outlook determines that you have a slow connection. To manually synchronize all of your folders, on the Tools menu, point to Send/Receive, and then click Send/Receive All. To synchronize one folder, select the folder, click the Tools menu, point to Send/Receive, and then click This Folder.
My browser doesn't show my Web pages when I work offline.
When you update Web pages that you have made available offline, they are saved in a format that can be read only by Microsoft Internet Explorer. Therefore, other browsers can't display Web pages unless you are connected to the Internet or to a server.
I use Outlook with a slow connection.
It is recommended that you use Microsoft Outlook in Cached Exchange Mode using a Microsoft Exchange Server e-mail account. Cached Exchange Mode will automatically adjust the amount and type of data transferred to your server when a slow connection is detected. For example, Outlook may only download headers rather than full items when a slow connection is present. When you view an item in the Reading Pane or open an item, the full item is retrieved from the server. The need to work offline is greatly reduced with Cached Exchange Mode.
If you do not use Cached Exchange Mode or want greater control over which folders or items are synchronized, you can switch to offline state.
When you run Outlook offline, you periodically synchronize with the Exchange server to send and receive messages and to synchronize other offline folders. You can synchronize manually or by using Send/Receive groups.
When you are using a slow connection, you use Outlook offline and synchronize periodically. The connection time is generally short if you synchronize often, and your data is available when it is not convenient to connect to the server, such as when traveling. The disadvantages of working offline are that a duplicate copy of the data is stored on your computer's hard drive, and that, to remain useful, you should synchronize frequently.
It is possible to connect directly to the Exchange server over a slow connection. With this method, no synchronization is required. Any messages you open will be downloaded to your computer. This allows you to download new mail selectively without having to download all new messages. Another advantage is that you can send mail immediately after you compose it. The disadvantage of this method is that large messages you receive will take a long time to download over a slow connection, and Outlook will be unavailable until the message is downloaded.
I get an error when I try to add an existing Offline Folder file (.ost).
In order to use an existing Unicode Offline Folders file, you need to use a Personal Folders file (.pst) that supports Unicode or disable the use of .pst files by changing the delivery location to your Microsoft Exchange Server mailbox data file.
To resolve this problem, you can either disable the .pst file by delivering new e-mail messages to your Exchange server mailbox data file, or by changing the delivery location for new e-mail messages to a .pst file that supports Unicode by selecting an existing Microsoft Outlook Personal Folders file (.pst) or by creating a new Microsoft Outlook Personal Folders file (.pst).
Do one or more of the following:
Identify an existing Personal Folders file (.pst) that supports Unicode
Create a Personal Folders file (.pst) that supports Unicode
You can assign a password to the file. A password improves security and reduces the ability of others to view your data. You can select the Save this password in your password list to avoid being prompted for the password each time you open the file. Use strong passwords that combine upper- and lowercase letters, numbers, and symbols. Weak passwords don't mix these elements. Strong password: Y6dh!et5. Weak password: House27. Use a strong password that you can remember so that you don't have to write it down.
Note If your Microsoft Windows user account is not password-protected or other people have access to your Windows user account, do not use the Save this password in your password list option.
The name of the folder associated with the data file appears in the Folder List. By default, the folder is named Personal Folders.
Change the default delivery location for items to the Exchange Server mailbox data file
When Outlook runs in non-Unicode mode on the Microsoft Exchange server, the code page-based system is used for character mapping. In code page-based system, a character entered in one language may not map to the same character in another language. Therefore, you are likely to see incorrect characters, including question marks. Additional information on scripts and code pages is available in Outlook Help.
For example, consider two people
To resolve this issue, disable Offline folders, close and restart Outlook, and then create a new Offline folder file and synchronize the data.
If you do not share messages and items with people who use Microsoft Outlook on computers that run in other languages, you can run Outlook in Unicode or non-Unicode mode on the Microsoft Exchange server. A disadvantage of running in non-Unicode mode is that the Offline Folder file used for the profile will be created in the format that does not offer greater storage capacity for items and folders. Therefore, if the size limit of the Offline Folder file is a concern for you, then you should run Outlook in Unicode mode on the Exchange server. To switch to Unicode mode, contact your administrator.
If you work in a multinational organization or share messages and items with people who use Outlook on systems that run in other languages, Outlook should run in Unicode mode on the Exchange server. This will also ensure that Unicode-capable data files are used for the profile that has the capability to store multilingual Unicode data. To switch to Unicode mode, contact your administrator.

Note Since Outlook 2000, the body of Outlook items has been Unicode, and the body can be read irrespective of the language in which the item was created. However, Outlook data, such as To and Subject lines of messages and ContactName and BusinessTelephoneNumber properties of contact items, will be limited to characters defined by your code page if Outlook runs in non-Unicode mode on the Exchange server.
