Recently I had problem with my Outlook new message icon on taskbar.
The little envelope did not appear anymore when a new email arrived.
I had to check often Outlook for new emails.
The solution of the problem is easy:
Go to menu Tools.
Click on Options.
outlook-tools-options
In new popup window Preferences tab /first/, click on E-mail options button.
A new dialog window is opened. Click on Advanced e-mail options… button.
outlook advanced e-mail options
Third dialog window is opened.
Find and check the checkbox ‘Show an envelope icon on system tray.’
outlook show envelope
Click OK.
Now everything is OK – the envelope appears as expected.
