Count distinct values Issue with non unique
try the following formula:
countdistinctnonblank = CALCULATE(DISTINCTCOUNTNOBLANK(emails[link]), emails[link]<>"" && NOT ISBLANK(emails[link]))

Thanks a lot for such a quick response.
I tried all of your solutions and only themistoklis solution gave me the correct results:
themistoklis Do you know why I need to wrap around CALCULATE? Why just simple function DISTINCTCOUNTNOBLANK does not have correct results?
Hello ignas
I used 'Calculate' function as I had to apply filters (e.g. <>"" && NOT IS BLANK) in the formula.
You can only apply filters in a formula through the CALCULATE function.

I understand how CALCULATE function works. I just cannot understand why I cannot use only DISTINCTCOUNTNOBLANK function in this case? Why if I only use DISTINCTCOUNTNOBLANK it still gives me a value of 4 which means it still counts blanks.It has to do with your background data. PowerBI treats differently Blank, NULL and EMPTY values.
Maybe the following 2 articles will give you the answer:
