Safe mode is a function that is inbuilt in many popular applications, one of which is Outlook. It is a mode that lets users use the program with limited functionality when there are some problems with that particular program. Same is with Outlook, when things are not running properly in Outlook, the user can run Outlook in safe mode and finish their essential tasks.

Usually, a user launches Outlook in safe mode on purpose, but sometimes Outlook starts running in Safe mode by itself. Safe mode is good, until you have control over initiating it. But if it is getting initiated on its own every time, it is suggested that you start looking out for some solutions. There are many disadvantages of running Outlook in safe mode without any proper reason. In safe mode, you might not be able to save templates, smart tags, etc. So, if your Outlook is opening in Safe mode in its own, then this blog is going to help you through this problem.

Why Outlook turns to Safe Mode?

As a routine, Outlook keeps on updating system registry, so that newly installed programs work as they are expected to work. So, while this updating process, if Outlook finds any problem in the newly installed program it itself initiates the safe mode. So, as a sign of that something is not working properly, Outlook automatically initiates safe mode.

Sometimes, Outlook itself notifies you about the add-in or program that is creating the problem. In a small notification box, you will get the info of the faulty program on the screen, and from there you can uninstall it. But not every time you will get this luxury, and hence you would have to solve this problem on your own.

In older versions of Outlook like 2003 to 2007 Safe Mode may trigger due to problems arising with Windows Search service.

In 2010 version of Outlook the potential trigger for the safe mode is KB3114409 update. But for the newer version of the Outlook it can be wrong add-ins and many other reasons.
