Using classic Outlook for Windows in business environments
Belinda,
You should have the fix by now. Restart Outlook a couple times and see if the problem is cleared up yet.
If for any reason you still see the issue, start Outlook in Safe Mode and then restart back in normal mode. When you start Outlook hold down the Ctrl key until you see the prompt to click to Safe Mode. After you open in Safe Mode then close Outlook and restart normally. This forces Outlook to pull changes from the service quicker.
