Thanks for answer. Let’s see, I’ll try to explain better that I can, but be patient with my grammar.
I use Thunderbird 38.4.0 and install Lightning 4.0.4.1 and Provider for Google Calendar 1.0.4
I start my calendar in Thunderbird and add a new calendar using a private URL (the private URL of my calendar in Google Calendar). Then, i synchronize and all looks OK. The properties of my account allows me to add new events because the option “only read” is unchecked (I translate all because my Thunderbird is in spanish)
Now I add a new event, choose the right calendar (Google Calendar), set all the parameters IN need (date, title, etc.) and click the button “Save and close” and this is the message I receive few seconds later:
An error has occurred while writing to the Google Calendar calendar!
Error Code: MODIFICATION_FAILED
Description:
There’s nothing in the description by the way. Aditionally appears a warning icon at the right of my calendar in the left column. When I open te properties I see that the opcion “Only read” is checked. Remember, at the beginning this option was unchecked
I hope I have explained well. I will wait your answer.
