The body and any associated attachments are downloaded only when requested by you, or as necessary for synchronization with personal digital assistants PDAs , auto archiving, and some client-side rules.
In a slower connection environment, the Offline Address Book is also not automatically updated. However, you do have the option of manually requesting the update.
Note: Downloading headers only is a feature available when you connect to Exchange Server or Office Outlook Cached Exchange Mode takes advantage of the ability of Outlook to automatically determine the speed of your connection to Exchange, and it optimizes data transmissions for that speed.
When the On Slow Connections Download Headers Only setting is selected, Outlook stops automatically downloading full items and also leaves attachments on the server.
For example, you may use a laptop computer at your office and connect via a network cable to your corporate local area network LAN. You have access to headers and full items, including attachments. You have quick access to the server running Exchange. You can continue to work uninterrupted with your data. If the connection remains unavailable, Outlook switches to Disconnected , periodically checking for server availability. If you have wireless access, Outlook could reestablish a connection to the server and switch back to Connected status.
You aren't required to change any setting or restart Outlook. Later that day, you use a modem for dial-up access to your Exchange account. Outlook recognizes your connection is slow and automatically optimizes for that connection by downloading only headers and not updating the Offline Address Book. Additional optimizations are also made to reduce the amount of data sent over the connection. By offering different levels of optimization, Outlook can adapt to changing connection environments, such as disconnecting from a corporate LAN, going offline, and then reestablishing a connection to the server via a slower dial-up connection.
Note: Downloading headers only is a feature available when you connect to Exchange or later. You always have the option to manually set the connection behavior. In some cases, you may want to control your connection behavior and the amount of data transmitted to and from Exchange.
At the office, when connected to a high-speed local area network LAN , Download Full Items is probably the best option. If you connect via a service that charges by the amount of data you send and receive, which is common with cellular and GPRS connections, select Download Headers.
The amount of data sent over the connection is reduced and your connection time shortened. You can then request only the full items you need. Note: Downloading headers only is a feature available when you connect to Exchange or Exchange On the E-mail tab, click the Exchange Server account, and then click Change. You do not have an Exchange email account in your Microsoft Outlook profile This feature requires that your Outlook profile contain an Exchange account.
Your Exchange administrator may have disabled this functionality Exchange administrators have the ability to disable this feature in Outlook. Additional information for administrators is available in the Microsoft Office Resource Kit. However, installing the Terminal Services Client or the Remote Desktop Connection client does not prevent access to this feature. When you are using Cached Exchange Mode, a message may remain in the Outbox for up to one minute until the next synchronization with the server running Exchange occurs.
To turn on or off shared folder support when using Cached Exchange Mode, after step 2 in the above procedure, click More Settings , and then on the Advanced tab, select or clear the Download shared folders excludes mail folders check box. Top of page. On the Tools menu, click Account Settings.
LM hashes inherently are more vulnerable to attacks because: — LM hashes require a password to be less than 15 characters long and they contain only ASCII characters.
Where are Windows credentials stored? Windows credentials are composed of a combination of an account name and the authenticator. This database contains all the credentials that are local to that specific computer, including the built-in local Administrator account and any other local accounts for that computer. The SAM database stores information on each account, including the user name and the NT password hash. No password is ever stored in a SAM database—only the password hashes. This means that if two accounts use an identical password, they will also have an identical NT password hash.
This allows users to seamlessly access network resources, such as file shares, Exchange Server mailboxes, and SharePoint sites, without re-entering their credentials for each remote service. If the user logs on to Windows by using a smart card, LSASS will not store a plaintext password, but it will store the corresponding NT hash value for the account and the plaintext PIN for the smart card.
If the account attribute is enabled for a smart card that is required for interactive logon, a random NT hash value is automatically generated for the account instead of the original password hash. The password hash that is automatically generated when the attribute is set does not change.
If a user logs on to Windows with a password that is compatible with LM hashes, this authenticator will be present in memory. The storage of plaintext credentials in memory cannot be disabled, even if the credential providers that require them are disabled. I hope you found this blog post helpful.

The number that is assigned to this policy setting indicates the number of users whose logon information is cache locally by the servers. If the number is set to 10, the server caches logon information for 10 users.
Users who access the server console have their logon credentials cached on that server. An attacker who is able to access the file system of the server could locate this cached information and use a brute force attack to attempt to determine user passwords. To mitigate this type of attack, Windows encrypts the information and obscures its physical location. Configure the Interactive logon: Number of previous logons to cache in case domain controller is not available setting to 0, which disables the local caching of logon information.
Additional countermeasures include enforcement of strong password policies and physically secure locations for the computers. Users cannot log on to any computers if there is no domain controller available to authenticate them. Organizations can configure this value to 2 for end-user computers, especially for mobile users. A configuration value of 2 means that the user's logon information is still in the cache, even if a member of the IT department has recently logged on to the computer to perform system maintenance.
This method allows users to log on to their computers when they are not connected to the organization's network. Skip to main content. This browser is no longer supported.
