I want to reopen a closed Opportunity record.
I can't edit some of the information on the Opportunity record form.
I can't open a history item linked to an Opportunity.
The link between the history item (history item: An item such as an appointment, business note, e-mail message, file, or task that is linked to an Account, Business Contact, Opportunity, or Business Project.)
and the Opportunity record (Opportunity record: The location for storing Opportunity information, including information that is entered on the Opportunity form, linked records, and communication history items.)
has been broken. The item was moved to a new location or deleted. If you want to restore this link, you must link the history item to an Opportunity record again.
I can't see the Opportunities folder in the Navigation Pane.
