Getting this exception repeatedly while writing email's

Answer 1

Dear Keerthivasan Karthikeyan,

Good day!

Thank you for posting to Microsoft Community. We are happy to assist you.

As you mentioned "while writing email's", this error is occurring when you write email, May I know, the email type that you are writing? (Such as, any code related email, scripts).

May I confirm, when you write email from Outlook Web App, does it make any difference or same issue? 

To narrow down the issue, please kindly provide us the above information including your Outlook version, we will analyze further.

We look forward to your response.

Thank you for your precious time, Have a nice day!

Sincerely,
