Unshare or change sharing for a record

In the list of records, select the record that you want.
Or, select multiple records
- Select several records by pressing the CTRL key while you click each record.
- Select a sequence of records by clicking the first record that you want, and then press the SHIFT key while you select the last record that you want.
- Select all records on the page by selecting the Select/clear all records on this page check box at the top of the list.
  By default, the Microsoft Dynamics CRM Online Web application displays 50 records per page. You can increase the number of records displayed and thereby increase the number of records you can select at one time. To display up to a maximum of 250 records per page:
  1. On the Tools menu, click Options.
  2. On the General tab, in the Records Per Page list, select the number of records to display per page.
  3. Click OK.
  This changes the number of items that is displayed for all lists, which may slow response time when you switch record types. Therefore, you might want to set it back to a smaller number when you are done with this bulk action.
On the Actions toolbar, click More Actions, and then click Sharing.
To remove a user or team, in the row for the user or team whose rights you want to change, select the check box, and then under Common Tasks click Remove Selected Items.
- OR -

To edit permissions on a record for a user or team, select or clear one or more permissions check boxes, such as Read or Delete.
Click OK.

Notes

To cancel any changes that you have made and retain the previous permission settings, click Reset.
