Hi there,
I googled the internet like crazy but I could not find a solution for my problem:
A very important milestone in our project takes place on a public holiday (Germany). However, I cannot delete this day in the project calender (also not the it is e.g. shown here https://software.grok.lsu.edu/article.aspx?articleid=7481).
The project calender looks different:
Here you see that “delete” appears grey and cannot be chosen
I would be very pleased if anyone could help me with this problem.
Thank you in advance.
