Very slow response and application crashes

Since I upgraded from Office 2010 to 2013 I have noticed a massive general performance drop, and Word and Outlook hang for long periods of time. The screen is usually greyed-out and/or with a "waiting" cursor. The only option is either to wait for ten minutes or more, or to kill the application from the task manager.

 The worst aspect of this is if you try to re-index an existing document, what used to take two to three minutes can now take up to ten times as long, and often the application crashes and the document cannot be repaired.

Is anyone else having these issues, or do you have a solution as this is really causing me a lot of grief?

Welcome to Microsoft Community and thank you for posting the question.

I will assist you to resolve the issue you’re experiencing in Word and Outlook.

Let’s start the Office application in safe mode and verify whether issue re-occurs. Follow the below mentioned steps to start Office application in safe mode:

* Hold Windows key + R.
* Copy and paste, or type the following command in the Open box, and then press Enter:
Outlook /safe
Note: There is space between Outlook and '/'. Replace Outlook with WinWord to start Word in safe mode.
If Word/Outlook safe works, disable the add-ins following steps mentioned below and determine the problem causing add-in:
a) Click on File menu, click Options, Add-ins, Go button besides Manage: Com-in Add.
b) Check if there are add-ins listed, clear the check box.
c) Close the Office program and restart it.
d) Disable each add-in one at a time, restart the Excel/Word, and repeat the above procedure. If the issue reappears again, it will help you to determine which add-in is causing this issue.
