Hi @Natjira Yodpunya ,
Welcome to our forum!
Can you open Outlook or other Office programs successfully? Is there any error when you open Office programs?
If there're any problems when you run Office programs, please provide more information about the exact problems for our better research.
If everything is OK, please kindly understand that the Outlook tag here we mainly focus on general issues about Outlook desktop client. Considering that the issue is related to your Kespergy program and we know little about it, it's suggested that you could post your issue in dedicated forum for Kaspersky for more professional help.
Thanks for your kindly understanding and support!
