Dear Majedul,
Greetings! Thank you for posting in Microsoft forum.
From the screenshot, I noticed your Office apps are still appearing as Office Professional Plus 2019 and this is the reason FILTER function doesn't appear. Please try the following steps to activate with your Office 365 Pro Plus account:
- Open any Microsoft 365 app, sign out (sign out from all the accounts you are currently signed in with) and close all the Office 365 applications opened on your system. To sign out, open any Office application, let’s say Word or Excel, click File>Account>Sign out and then quit all Office apps.
- Open Control Panel>User Account>Credentials Manager>Windows Credentials.
- Under Generic Credentials, look for any entries containing MicrosoftOffice16 and MicrosoftOffice15 credentials and Remove all.
If you don’t see MicrosoftOffice16 and MicrosoftOffice15 in Control Panel>Windows Credentials, then simply sign out from Microsoft Office apps and enter your Microsoft 365 log in credentials and **then re-start the Office app (**re-starting the apps is necessary after signing in with Microsoft 365 credentials).
If the issue remains, please repair Office apps from Control Panel instead.
- Click the Start button > Control Panel. From Category view, under Programs, select Uninstall a program.
- Click Microsoft 365 apps, and then click Change and select Online Repair.
Please try Online repair. Quick repair only detects and then replaces corrupted files, and an Online repair option will do a complete repair; it will take a few extra minutes to repair Office applications.
After repairing Office apps, check if you see the mentioned functions in Excel. If you need any help, let us know. We will look forward to your reply. Stay safe and stay healthy.
