This error happened on one of my client machines today. Every time Outlook 2013 was opened this error would pop up:
Script Error: An error has occurred in the script on this page

Do you want to continue running scripts on this page?
These sort of errors can be caused by bad or corrupt add-ons so I started outlook in safe mode using outlook.exe /safe in a run box but still I got the script error.
I noticed that Outlook 2013 was opening to personal folders by default.
I changed the default opening folder to Inbox instead. (See: How to change default startup folder in outlook)
Then when I opened outlook it opened normally. If I selected personal folders the script error occurred again.
So it turns out this error is something to do with the personal folders.
I decided to do an online repair.
After that the error was fixed. I am not really sure what caused this error, but it seemed to fix it. If anyone knows how to the reason behind this error please let me know.
