How to enable and disable Outlook filter

Show or hide items or files with a view filter

1. Click on the folder for which you want to apply a filter.
2. On the View menu, point to Current View, and then click Customize Current View.
3. Click Filter.
4. Do one or more of the following:
• Filter using common filtering criteria    
• On the Messages tab, select the filter options you want.
• Filter using additional criteria, such as a category or importance level    
• Click the More Choices tab, and then select the filter options you want.

If you select more than one filter option field in the Filter dialog box, only the items that meet all of the criteria will appear. However, if you use one filter field, and enter multiple criteria, items that meet at least one criterion within that field will be found.

For example, if you type Joanna Fuller, Florian Voss, and Jon Morris in the From filter field, you will find messages that are from one, two, or all three of those people.

• Filter using custom criteria    

1. Click the Advanced tab.
2. Click Field.
3. Point to the field set you want, and then click the field you want to use in the search criteria.
4. In the Condition list, click the condition you want to use with the selected field. The conditions that are available depend on the field that is selected.
5. If the condition requires a value, enter the value you want the field and condition to meet in the Value box.

Remove a view filter
