Hi Raja,
Thanks for contacting us,
I'm sorry to hear that you are having trouble with inserting symbols in the new Outlook.:
- Place your cursor in the email at the spot where you want to insert the symbol.
- Go to **Insert** > **Symbol**.
- Pick a symbol, or choose **More Symbols**.
- Scroll up or down to find the symbol you want to insert.
- Click **Insert** and then close the dialog box.
If you don't see the **Symbol** option under the **Insert** tab, you may need to double click on the email to open it in a new window, then click **Reply**. Then it will open a new window to let you compose the email. Under this circumstance, you should have the **Insert** button and insert the symbols.
I hope this helps!
Regards, Sola
