Hi, am not finding anything helpful in the support area, so hoping someone can help me solve. When a calendar reminder pops up, and I try to snooze or dismiss, I get this message:

Status Code: 2,147,500,037, null

Server Replied with 400 If you’re seeing this message after snoozing or dismissing a reminder and this is for a calendar you do not want to add or edit events for, you can mark this calendar as read-only to avoid such experience in future. To do so, get to the calendar properties by right-clicking on this calendar in the list in the calendar or task view.

Thing is, I do want to add and edit events, so I have no other options and the reminder keeps popping up every couple of minutes it seems. Any help resolving is appreciated. Thx!

I am new to Thunderbird and have my non outlook email account added and set up. During install I failed to add the calendar associated with the email.

How can I add this email calendar now?

Thank you. Brucebold text

I'm a retired IT Tech and supported MS Outlook with Exchange for years. Lately I've tired of the constant bickering between Google and MS that just seem to make using Outlook at home difficult. I've been working on Migrating from MS Outlook to Thunderbird v147.0.1. I had a large PST file with Saved Items and it's been a struggle to process all that but finally got connected to Gmail, converted/imported the PST items and then began working on Calendar. Finally got all that working and I'm now having trouble getting Google Tasks connected to Thunderbird. Google doesn't seem to be exposing the Tasks feed via CalDAV. Has anyone run into this before and does anyone have any suggestions to resolve? Thanks.

I have ended up with five different calendars. They all have different names--probably because I really don't understand how Thunderbird organizes things in regard to the rest of the internet. Several people in our household share calendars, to keep track of events, tasks due, and medications.

So how do I consolidate all the entries in all of these calendars? I have tried syncing, but that doesn't seem to work. How can I know that when I enter a soccer schedule on (one of) my calendars, it will end up on the calendar that my wife uses to print out our family weekly schedule?

using thinderbird and export we could have calendar.ics and calendar.html now it is impossible to save in html. please help. It was so perfect the calendar saved in html, so we could print all the data perfectly Now the results says that error happen and olny ics type can work

When synchronizing via CalDAV with T-Online, Thunderbird almost always prompts for a password, even though all data is saved. T-online says, this ist problem from thunderbird.

I created a backup of my Thunderbird in Debian. When I try to import the calendar data from backup.zip, I only get the names of the calendars, but not the contents! How can I test whether there is any calendar data? Many thanks for any advice, Günter

mac calendar keeps wanting me to use a password for Safari, which I do not use, which then passes me on to Chrome. Plus calendar is not syncing with phone anymore. Help

Hello,

since some years I use the facebook calender url in the calender tab.

Since some days the are no entries shown anymore.

The same calender url is correctly used in google calender (web & app)

The facebook url is as followed:

https://www.facebook.com/events/ical/upcoming/?uid=100001094911980&key=XXXVO6gUO0v9U63j

It would be helpful to have a solution or at least an explanation for this problem.

How does the 'Covert to Task ...' function work on an email? When I click the Convert to task, nothing happens. I was expecting to see a task in my task list. Where does it go? I have a 'Task calendar' and a Google calendar in my list.

Hi, I am trying to export a calendar from a Windows 10 PC into a Lubuntu PC. The exported Home.ics file is about 217KB. At stage 4 in the import process (which shows the file name correctly) a message in red says "No importable items found in the file" . In the main area it says "Loading items" but nothing happens. Am I missing something here? Thanks

My pc calendar display is blank. I can create new event in Thunderbird on my pc and it is immediately appears in my google calendar on my mobile phone, but does not appear on my Windows 11 PC.

In earlier versions, the calendar list button appeared in the left sidebar, so I could decide which calendars to display and change the default color. But I can't find this now. How can I change an existing calendar?

I'm using the latest version (145) and I've setup my office 365 email account. I'm trying to setup my calendar account as well but when I enter location, username and password it says that my credentials were not accepted.

I assume this means that TB is using legacy un/pw authentication which is no longer supported instead of OATH2. There is, however, no option to select OATH2 in the calendar setup process (like there is for email).

Are office 365 calendars supported by TB 145?

I want to just search my calendars, but the search bar only seems to look up emails, not calendar items. I know I was able to do it in the past. Attached are two images.1) of me putting the search bar into the calendar tab and 2) of the search bar showing up there - but when I search all that comes up are emails.

Dear Support Team,

Could you please make the "Busy" and "Out of Office" colors in the form (screenshot attached) more distinct from each other?

Currently, they are very hard to tell apart visually when assessing an employee's availability in the calendar.

Thank you for your consideration.

Hi There,

It would be helpful if I could print out (hard copy) various options (day/week/month etc) from my Thunderbird Calendar.

I can't see any facility to print our these views.

Is there a print function within Calendar?

Thanks

Hi, my Thunderbird calendar reminders are coming up 4 hours after the meeting.

Running Kubuntu. System locale/timezone OK, TBird set to use system time (though manually making it the same didn't help). HW Clock matches system time. Pacific/Auckland.

Tried exporting all my appointments and re-importing them - no change.
