Disable Add-ins | Outlook Opening in Safe Mode
Microsoft Outlook can be extended with additional features or functionalities if you install add-ins. There can sometimes be a lot of trouble with the installed add-ins.

Outlook automatically installs updates by default. However, you can disable or enable them in your Office Account settings. The latest updates can also be installed on your device by checking for them.

Look for Dialog Boxes
Outlook asks for confirmation when performing certain actions. Outlook displays a message if you choose the Dismiss All option on a list of reminders. Unless you select an option from that dialog box, you won’t be able to perform that action.
Outlook is unable to respond properly to these dialog boxes. Be sure there are no dialog boxes open on your system. Using Alt+Tab, you can see which dialog boxes are open. From there, you can switch between them. This will help you discover which dialog boxes can be dismissed.
Configure Outlook Mail Server
Make sure your mail server settings have not changed so that Outlook will continue to work as it does.

You cannot edit your settings directly if you use Gmail, or if your email address ends with @live.com or @hotmail.com. You can skip this step, as Windows manages these settings on your behalf.
