I-Thunderbird Isithangami Sokwesekwa

Information on how to add the Google 'Tasks' into Thunderbird Calendar: I have a gmail imap account using OAuth2 as Authentication Method.

File > New > Calendar, select 'Google Calendar' >  click on 'Next' choose or enter: gmail email address   > click on 'Find Calendars' Select 'My Tasks' and click on 'Subscribe'

You may be asked to enter password as per Oauth2 Authentication.

See image. It shows the selection available when you follow instructions. It shows where 'My Tasks' is located in the Calendar list. I selected 'My Tasks' and then clicked on 'Task'. Create the Task and save. Task is shown in Thunderbird and on the right side you can see the Task is displayed via the webmail access using a browser.

I am running Thunderbird 91.5.0, I have installed TBsync, google4-tb sync, Provider for exchange Active sync, Provider for Google Calendar. Still my TB calendar does not sync with my Google Calendar. I am suspect that I am doing something wrong, please help. Thanks in advance. Dan

I upgraded to version 91 a while ago and the calendar invitations are not being set to me or the other invitees. I am currently at version 91.2.1 but this is the first calendar item with attendees. This has worked for years. I am on windows 10. I use the local Thunderbird calendar.

I can see the calendar and am getting an error when I right-click the calendar and go to the properties that says "If you want to use this calendar to store invitations to or from other people you should assign an email identity below."

But there is nothing in that box that gives me the ability to assign an email.

How do I fix this?

My thunderbird system got upgraded to 91.2.0 (64 bit).

Now when I receive meeting invites (probably through *.ics files) they are displayed without any indication of the meeting date/time time (see attached screenshot). For a new meeting I can accept/tentative/deny them but not see details, and once I've done that there is a details button that will actually show me the proposed date/time but no way of denying it. This makes it almost impossible to decide whether I need to accept or deny the request.

The only way around I have found so far is to look at the message source, figure out the date/time from there, but that is very, very awkward and time consuming.

I found out that when you click the triangle before the inviters name, the actual request is shown, with the date/time information. This makes it workable, but the question remains why a lot of meeting information is shown, but not the time. My guess is only the description is shown and not the important additional meta data.

I do like the fact that the links are now actually clickable in the actual meeting entry, that is a huge usability improvement.

The actual meeting request (sensitive info removed/replaced with dummy info:

Hi! I've googled but I can't find/understand the answers... I just downloaded thunderbird to try and want to use the calendar function. I just can't manage to add my husbands calendar. I see it when I am logged in on my google account. Thanks, Jaqueline

I'm migrating to a new computer and from Windows 10 to W11. I have successfully exported/imported the contacts using the export tool, but cannot figure out how to ex/im the calendar. I am using a SanDisk drive to move the files. Both systems have TBird 102.1.2 (64-bit).

Please give step-by-step instructions to do the calendar (only) ex/im. I do not use the Mail feature.

Network calendars no longer seem to be working after upgrade to Thunderbird 102.4.1.

For example, my previously working calendar to this Google vCal calendar no longer syncs. I also had working read/write network CalDAV calendars that are now broken.

I tried deleting and recreating the calendars, but to no avail. Any help would be appreciated.

Here is some output captured from the Thunderbird error console:

I'm getting an 'credentials not accepted' error when connecting my Google's universal contacts/birthday-calendar with CalDAV. This error occurred after upgrading Thunderbird to version 91.x.x in previous versions, maybe even an early version of 91.x.x I had no problem connecting the birthday calendar. All other (Google) calendars (also using CalDAV) work fine. I have this problem on two PC's both running Dutch Thunderbird 91-last version under Dutch Windows 10 Home-edition, also witl all the latest updates installed.

Steps to reproduce: Subscribe to the birthday calendar of my Google account. Note: As I'm using the Dutch localized versions, my translations can be different from the English menu-items.

Preparation in Google:

• In your web-browser look up your Google 'Calendar-ID' (aka calid) which can be found in the online settings menu in Google calendar at: https://calendar.google.com/

Look for it in the 'Integrate calendar' section. (In Dutch: Zoek het Google 'Agenda-ID' op in het online 'Instellingen'-menu van Google agenda, te vinden onder de sectie: 'Agenda integreren'.);

• Use the URL-syntaxis: https://apidata.googleusercontent.com/caldav/v2/<Calendar-ID>/user

in which <Calendar-ID> is your Google Calendar-ID in the steps below. More information at: https://developers.google.com/calendar/caldav/v2/guide

• Note: Google's birthday calendars all have the same generic/universal 'Calendar-ID' and therefore URL. They are uniquely identified by the username (Gmail-address) logging in.

Steps in thunderbird for adding the BIRTHDAY calendar:

1. Create new calendar;
2. Select 'On the network', next;
3. Input:

• Username: <Your Gmail-address>
• Location/URL: https://apidata.googleusercontent.com/caldav/v2/addressbook#contacts@group.v.calendar.google.com/events

1. Click: 'Search calendar' and provide your password when asked.

Actual results: The screen returns with an 'credentials not accepted' error. Not connecting to the birthday calendar. (The error in Dutch: 'De ingevoerde referenties werden niet geaccepteerd. Controleer uw instellingen'.) Screenshot included.

Expected results: Connecting my birthday calendar in Thunderbird.

What I did/also tried:

• I removed all my Google calendars and had no issue reconnecting them again. Except for the birthday-calendar;
• I tried to put the birthday-calendar in read only mode by adding '.readonly' at the end of the URL. See the links provided in the preparation;
• Turned off all my addons with no effect;
• I reinstalled Thunderbird on one of my PC's, actually I reinstalled the full PC. Without result;
• Posted bug ID 1746395 without result.

I checked.. * Questions:

• Like 1352307, 1352226, 1311079 and 1317744. The last question resulting in bug 1682177.

* Bugs:

• 1682177 connecting to two birthday calendars;
• 1735525 connecting to a calendar shared with a Google account in Google itself;
• 1737414 connecting to a Google calendar using a Google account without Gmail.

So I'm hoping anyone here can help. Thanks in advance!

No calendar data showing after upgrade. calendar-data folder has local.sqlite which appears to be intact with all previous calendar info but nothing displays. I added a test event and it appears. The alert appears at the appropriate time but the alert cannot be dismissed. When I restart Thunderbird the calendar shows empty again but I can see that the new test event is present in local.sqlite. See error console below

I've been using Thunderbird for work for a few years and a few months ago my calendar integration with my Google Calendar stopped working. I've tried everything I can think of including re-installing calendars, but without success. My Thunderbird at home can still accept invites, but not on my work computer despite verifying that the calendar address and such is the same.

Initially, when I'd click 'Accept' on an invite, nothing would happen (ie no prompt, failure etc), the invite would just stay there without response. Now it's asking me if I want to link it with one of two different calendars I have, both of which I've verified under the calendar on Thunderbird that it isn't associated with an email address (has the yellow bar at the top saying if you want to use this calendar to store invitations you need to associate with an email address).

I can't think of what to do for next steps for troubleshooting, any thoughts?

It's not on settings. I found this css code but don't know how one installs css for thunderbird. I got as far as opening the config editor on the calendar options. But I don't see what entry it is.

Alternatively if I can change the weekend colors that would work well. They are nearly the same yellow as the CURRENT color.

Thanks!

I am running Thunderbird on Linux, using version 91.4.1 (64-bit). My OS is set to use a 12 hour clock, yet all times in Thunderbird use a 24 hour clock. I checked out the help article, and it seemed to indicate having the locale set to English (United States) in preferences should get me the 12 hour clock, but both Application locale and Regional settings locale show that option. Switching does not change anything. I tried looking in the config editor, but I was unable to locate any of the settings to change time formats mentioned in the help article.

Why is Thunderbird stuck on a 24 hour clock?

The help article I tried: https://support.mozilla.org/en-US/kb/customize-date-time-formats-thunderbird

I followed the instructions here: https://support.mozilla.org/en-US/questions/1364439 After pasting in the URL of the Google Calendar from the browser, the process asks for the password used for the Google account. I provide the password, but the response is "The credentials you have entered were not accepted."

To confirm that the user name (my Gmail account) and password were entered correctly, I logged out of Calendar on the browser and logged in again using the credentials that were refused by the Create New Calendar process.

This isn't a showstopper, but it would be nice to have the calendar in Thunderbird.

I am using Fedora Linux, KDE desktop. The Thunderbird calendar page shows all times on a 24 hour clock. I need this to be in a 12 hour AM/PM format.

I've tried exporting LC_TIME="en_US.utf-8" and LC_ALL="en_US.utf-8" but that doesn't make a difference.

The clock in my task bar does show 12 hour AM/PM format, so my desktop, in general, has the correct format, but the Thunderbird calendar appears to be ignoring that setting.

How can I force Thunderbird calendar to use a 12 hour AM/PM format?

I have just installed Thunderbird and connected it to my Outlook356 account in IMAP mode. I see emails and folders, no problems. However in the initial setup, it did not discover my calendar and I have not been able to get Thunderbird to connect to it manually. I go to Create New Calendar, click On the Network, put in my username (my outlook email address) and use outlook.office365.com as the location, with Offline Support ticked. When I click Find Calendars it asks for my password for outlook.office365.com, which I enter, then it comes back with "The credentials you have entered were not accepted. Please check your settings.". I know the password is correct. It is the same one I used to get the emails side of things working. I have also been able to successfully connect Bluemail to my outlook365 account and have both emails and calendar working in it - it's just not as rich an environment as Thunderbird, which I would prefer to use (I'm fed up with the Outlook client and want to get off it!). Any clues on what I might do to resolve this calendar connection issue? Thanks, Nick.

I am facing three problems: 1. I cannot edit entries in my calendar, even though the read only box is unchecked in Calendar Properties. 2. I cannot change the location of my calendar in Location in Calendar Properties. Right now it is saying it is Home.csv even though my calendar is stored in Home.ics (see attached image). 3. no calendar reminders are showing up even though "show the reminder dialogue box" and "show missed reminders for writeable calendars" are checked under Calendar preferences (see attached image).

I am running Thunderbird 91.5.1 on a Wiindows 10 desktop.

Any guidance that can be provided would be greatly appreciated

So it seems that "Options" has since changed and is now called preferences. However under this submenu, based on some old screenshots, there used to appear a "Calendar" section on the left hand side. This is where some older posts showed where you would go to make that change.

However that is no longer there. So where do I go to modify this? Don't think it makes a difference but I'm using Windows 10.

Hi, I've searched a lot here and on other websites. I want to integrate the thunderbird calendar with the outlook.com calendar, not the Microsoft Outlook calendar. How to do so? I did publish the .ics file from outlook.com settings but do not know what to do now. Really lost. Please advice. Thanks Mohamed
