All about Safe mode in Microsoft Office
Safe Mode is a special way for Office apps to run when things aren’t working properly. Here’s how to use Safe Mode, if Office doesn’t offer it automatically, and what Safe Mode does differently.
Safe Mode is useful in situations where you cannot open files in normal mode because the app is crashing, or you might want to verify if an add-in or extension might be causing a problem during start-up.
When you start an app in safe mode, it’ll load in disabling add-ins or extensions, and won’t include toolbar / ribbon customisations. More on that below.
Automatic Safe Mode
Most likely, you’ll first see Safe Mode when it’s offered automatically. Office detects when one of the apps closes in an unusual way and when next started, it’ll offer Save Mode,
Sometimes Safe Mode is helpful but other times it’s not necessary. Office can’t detect why an app closed abnormally. It might be a problem with the Office app or it could be something totally unrelated such as Windows crashing or another program causing trouble.
All that means, don’t panic, if you see the Safe Mode suggestion. It might not mean there’s any problem with Office programs at all.
Is Safe Mode running?
Safe Mode is always clearly shown on the top title bar.
Forcing Safe Mode
There are two ways to force your Office apps into Safe Mode. That’s useful if Word, Excel, PowerPoint etc aren’t behaving correctly. Starting in Safe Mode can help isolate if the problem is with some addin or customization because Safe Mode blocks many of the extras that can load with Office.
First, you’ll need to find the shortcut icon for your Office app, that can be on the Start Menu or elsewhere.
Press and hold down the CTRL key and double click on the application shortcut.
A dialogue box will appear confirming to open the app in safe mode, click Yes.
Another way is to start the run app, start it by using Windows Key + R.
Next, type the following depending on which app you want to open in Safe Mode, then press OK.
- For Excel: Type excel /safe
- For Outlook: Type outlook /safe
- For Word: Type winword /safe
- For PowerPoint: Type powerpnt /safe
- For Publisher: Type mspub /safe
- For Visio: Type visio /safe
Leaving Safe Mode
Want to leave Safe Mode? Just close the Office application, then restart it.
