Dear Saba Pathan
Good day! Thank you for posting to Microsoft Community. I am happy to help you
I have done testing here and I can currently use this function normally:
I understand that you can see this feature, so I suggest you try the safe mode mentioned in this document first to see if you can't use this feature in safe mode as well : Paste Special option is missing or not working in Microsoft Office - Microsoft 365 Apps | Microsoft Learn
If you have tried the above suggestions and this feature is still gray, in order to further help you fix this issue, I need to gather the following information so that I can investigate further for you:
- The screenshots of version information of Excel you are using (File - Account - version information)
- Does this happen in a particular workbook or in a particular Project?
I look forward to your reply. Thanks for your cooperation.
I hope everything goes well with you!
Sincerely,
