Hello Sally Griffiths1,
Thank you for choosing the Microsoft Community! We are happy to help you.
I understand you cannot find reactions on your business account, but you could see them with your education account. Please correct me if I am wrong.
You should be able to use reactions in a business account as well, may I know what version of Outlook do you have? What version of Outlook do I have? - Microsoft Support. Is it the same with Outlook Desktop and Outlook on the Web?
Kindly try to apply reactions following the steps below and let me know the result:
- Put your cursor where you want the emoji.
- Press Windows key + . (period) to open the Windows Emoji picker.
- Select a symbol to insert it in your email message.
- When you're done, select × to close the emoji picker.
For more details, please see Add flair to your email with emojis - Microsoft Support
We look forward to hearing from you; Please understand that our initial reply may not always immediately resolve the issue. However, with your help and more detailed information, we can work together to find a solution. Thank you for your cooperation.
Sincerely,
Simbarashe | Microsoft Community Moderator
