Add / Edit Note to Excel cell has disappeared

[Fencote]

I have opened a file I was working on yesterday and have noticed that the ability to Add / Edit Notes and Comments has disappeared from the 'right-click' menu for all cells.  I have not protected any cells or sheets within the Workbook but have no idea why its gone.  Any help would be appreciated.

If I'm not wrong then you are struggling with COMMENTS,,, do this,,, select the cell then right Click & from the menu find Hide/Unhide Comment,, hit once sets the comment appears (if is hidden) another sets comments disappear ( if is Un-hidden) .

@Rajesh-S Thanks for the reply.  I am aware of the menu that appears when you highlight a cell and 'right click'.  The issue is that the menu appears when I 'right-click' but the options to Add / Edit / Delete both Notes and Comments has disappeared from the menu.

I'd check in Safe mode (Win+R, excel /safe) if it works or not, next do Office repair.

It's unusual activity since Insert Comments & then others are built in commands,,, one you try SHIFT+F2 ,,,, I'm sure this will works.

You may try this as a trouble shooter:

Try this VBA Macro:

• To open the VB Editor  press Alt+F11.
• Insert a new module from Insert  then Module.
• Copy and Paste this code. 

Sub ShowCommandButtons()
   Dim bar As CommandBar
   For Each bar In Application.CommandBars
         bar.Reset
   Next
End Sub

• Save the WB as Macro Enabled *.xlsm.
• Press F5 to run the Macro.

N.B.

• Back to sheet & insure that the Comment/Note commands have been restored or not. 
• Remember Comments is available with every version of Excel but the Note is with higher versions only.
