Frequently Asked Questions

Why can't I unlock the sticky note even after accessing the properties window?

If the 'Locked' checkbox is greyed out, the PDF file itself may be restricted. Check if the document has a permissions password enabled by navigating to File > Properties > Security. You must enter the permissions password to lift the editing restrictions.

Does changing the default properties affect existing sticky notes?

No, selecting 'Make Properties Default' only applies to new sticky notes you create in the future. Any existing sticky notes that are already locked must be unlocked individually.

Can I delete a locked sticky note directly?

Generally, Adobe Acrobat prevents you from deleting locked annotations to avoid accidental data loss. You need to unlock the sticky note first by clearing the 'Locked' checkbox in the Properties menu before you can select and delete it.

How do I lock a sticky note to prevent accidental edits?

To secure a sticky note from being moved or edited, simply right-click the note, select Properties, and check the 'Locked' box. Click OK to save the setting.
