From Microsoft Writing Style Guide:
normally Don't use to mean often, usually, ordinarily, typically, generally, or a similar term.
Here is examples that I have:
But note that most information that is written in English is available worldwide and should therefore normally use ISO currency codes with a descriptive label.
If you expect your documentation to be used only in the same country from which the telephone number originates, use the national form of the number. Group the numerals according to the format that is normally used in the area or country.
In the glossary, specify your selected terms as follows:
- Use an initial lowercase letter unless the term normally starts with an uppercase letter.
- What is the reason to permit using "normally"?
- Which word would you use in these examples in place of "normally"? "Usually" and "typically" looks inaccurate to me, as well as "generally". Maybe "ordinarily" but I'm not sure; English isn't my primary language.
The examples are from The IBM Style Guide for technical writers.
Edit
From the answer by Mozibur Ullah:
I'm not sure why you are suggesting that 'usually', 'generally' and 'typically' aren't synonyms for 'normally'.
Well. As I said earlier, I'm not sure. But here are some excerpts from the IBM style guide:
generally Use to mean “in disregard of specific instances” or “in all instances.” For example, write “Generally, hot-swap devices can be removed and replaced while the server is operating.”
normally Use to mean “in a manner that does not deviate from a standard pattern.” For example, write “The process is running normally.”
typically Use to mean “in a manner or circumstance that conforms to the characteristics of a type or group” or “in typical circumstances.” For example, write “A hot-swap device typically has a handle that you can grasp to remove the device from its bay.”
As you see, IBM do allow "normally", but they don't consider "normally", "generally", and "typically" as synonyms.
