After years of development, password recovery software has been very fast, especially in the support of high-performance graphics cards, the cracking passwords speed of office 2016 version is 10 thousand/sec, the version of office below 2003 is up to 1 million/sec. If it is a simple password, such as "123, 123456, abcd", just a few minutes to crack out. Even if like "123456789 or abc123456" such a complex password, can also be cracked in 1 to 2 hours.
To get a better protection for office documents, I think the password should be more than 12 digits long and contain upper- and lower-case letters and special characters. If your language is non-English, you can also use your language characters as the beginning of the password (you need to copy to enter the password), so that security can be improved by several levels. This is because most password recovery programs do not support non-English language characters.

As mentioned above, low versions of Office encryption algorithms crack passwords very quickly. The higher the Office version the slower the cracking speed. So, try to choose a high Office version as much as possible.
What if my computer only has a low version of office 2003? Recommended that you use zip software (WinRAR, 7z) to encrypt. Because Zip compressed file compatibility is good, encryption security is much higher than office 2003.
All of the above points are suggesting that you set your office document passwords to be more complex, so that the passwords are less possible to be cracked. However, if you forget your password that will be very annoying. Because it's so hard to crack complex passwords on a regular computer, if you have set up a 12-digit complex password in a document of Office 2016, the cracking time will be over 1 month. So, it is very important to memorize the password.
