You can edit the default content-filter policy to configure your company-wide content filter settings. You can also create custom content filter policies and apply them to specified users, groups, or domains in your organization. Custom policies always take precedence over the default policy, but you can change the priority running order of your custom policies. Content filter settings include selecting the action to take on messages identified as spam, and choosing whether to filter messages written in specific languages, or sent from specific countries or regions.
Additionally, you can enable advanced spam filtering options if you want to pursue an aggressive approach to content filtering. Content-filter policy settings are applied to inbound messages only. Under Spam filtering click Edit or create spam content filter policies. If you are an admin of a different Microsoft plan, you access content filter settings directly through the Exchange admin center.
Click Add to create a new custom content-filter policy that can be applied to users, groups, and domains in your organization. You can also edit existing custom policies by double-clicking them. For custom policies only, specify a name for this policy. You can optionally specify a more detailed description as well.
You cannot rename the default policy. Note: When creating a new policy, all configuration settings appear on a single screen, whereas when editing a policy you must navigate through different screens. The settings are the same in either case, but the rest of this procedure describes how to access these settings when editing a policy. Click the Actions menu item in order to select the action to take on a message for each confidence threshold level Spam which is considered suspected spam or High confidence spam which is considered certain spam.
Possible values are:. Delete message Deletes the entire message, including all attachments. Quarantine message Sends the message to quarantine instead of to the intended recipients.
If you select this option, in the Retain spam for days input box, specify the number of days during which the spam message will be quarantined. It will automatically be deleted after the time elapses.
The default value is 15 days which is the maximum value. The minimum value is 1 day. Move message to Junk Email folder Sends the message to the Junk Email folder of the specified recipients. This is the default action for both confidence threshold levels. Add X-header Sends the message to the specified recipients but adds X-header text to the message header that identifies it as spam.
Using this text as an identifier, you can optionally create rules to filter or route the messages as needed. You can customize the X-header text using the Add this X-header text input box. Prepend subject line with text Sends the message to the intended recipients but prepends the subject line with the text that you specify in the Prefix subject line with this text input box.
Redirect message to email address Sends the message to a designated email address instead of to the intended recipients. Click the International Spam menu item in order to filter email messages written in specific languages, or sent from specific countries or regions. The service will apply the configured action. Select the Filter email messages written in the following languages check box to enable this functionality.
Click Add , and then in the selection dialog box, make your choices multi-selection is supported. Click ok to return to the International Spam pane. Select the Filter email messages sent from the following countries or regions check box to enable this functionality. Click the Advanced Options menu item in order to specify On , Off , or Test for each advanced spam filtering option.
On Messages are actively filtered according to the rule associated with that option. Messages are either marked as spam or will have their spam scores increased, depending on which options you turn on. Off No action is taken on messages that meet the spam filter criteria. All options are turned off by default. Test No action is taken on messages that meet the spam filter criteria. Developmental origins of central norepinephrine neuron diversity.

You can use the microsoft. A In some cases, when specific viruses are found on a system, the cleaner tool tries to repair infected Windows system files. Although this action removes the malicious software from these files, it may also trigger the Windows File Protection feature. If you see the Windows File Protection window, we strongly recommend that you follow the directions and insert your Microsoft Windows CD.
This will restore the cleaned files to their original, pre-infection state. A The tool does use a file that is named Mrtstub. If you verify that the file is signed by Microsoft, the file is a legitimate component of the tool. Double-click the Mrt. Windows More The MSRT differs from an antivirus product in three important ways: The tool removes malicious software from an already-infected computer.
