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:
On the Tools menu, click Options.
On the General tab, in the Records Per Page list, select the number of records to display per page.
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 Edit.
In the Edit Multiple Records form, make the changes that you want.
Any fields that you enter data in will change in all selected records. Other fields will be left unchanged.
Click Save.
