Hi @joel.wx
Thanks for your detailed case description.
the issue occurred every time.
Do you mean that there has been a problem with the icon display since you installed Outlook, or after you have done a specific action?
If the issue persists since you installed Outlook, you may try to repair office by going to Control Pane>Programs>Programs and Features>Select Office, right-click>Change>Choose the "Quick Repair" option first, and if that doesn't work, try the "Online Repair" option or uninstall and reinstall Outlook.
besides setting-up the homepage of specific folder, no other operations.
If the issue occurred after you set up the homepage of specific folder, would you please describe your detailed operation of setting-up?
Meanwhile, considering data file corruption, it is proposed that you create a new profile, re-add your account to the new profile and check if the same issue still occurs. Hope it helps.
