Hi Sergey,
thanks for the quick answer.
I think I had seen the notation with the .db somewhere and it used to work.
I tried now with the user name only and it works!
Thanks again for your support.
All login names we have seen before were in format
user@db_name
for server db_name.database.windows.net
SSMS tool doesn't require to input the "@db_name", so we add this part automatically now in Valentina Studio, too.
But in your screenshot, I can see that you have different format recupel@recupel.db.
The ".db" part - is something new.
Does it have specific meaning and it is impossible to connect without it?
