Thunderbird Community Forum

I had Thunderbird and switched to Outlook when I purchased Office. I liked Thunderbird better so I switched back. I exported my Outlook calendar and imported it to Thunderbird. The calendar works, no problem.

The problem is that when I open Thunderbird and select the calendar for the first time Thunderbird hangs. If I check the message indicates that Thunderbird is busy. After a period of time everything works. The only time this occurs is when I start Thunderbird and select the calendar for the first time. Can you tell me why?

If it makes any difference when I imported the calendar I did not realize how Thunderbird worked and I imported it creating a new calendar with the name of the imported file. I had a Home calendar with nothing in it and my imported calendar. I decided to export the calendar that was created during the import. I then imported that file to the Home calendar and deleted the original imported calendar.

My wife decided to add our son to our You Tube TV. She is not the greatest with computer. I have been unable to access my Thunderbird emails since Saturday. When I sign in I am asked to enter my email address and I get a 404 error message. I'll attach the messages I have received. Have to talk on phone if that is OK.
