For years I have used the extension 'Calendar Tweaks' because it colorizes the entire event in the calendar. This extension is no longer compatible with versions of Thunderbird after 74 so I have stop updation after Version 69. However in resolving problems with authorization I needed to update to the current Version of Thunderbird so my events in the calendar now just show the category color at the edge of the box instead of the entire box. Is there a way in Thunderbird to colorize the entire event box or another extension that does this.

I FOUND no close TOPIC.

Google calendar allows color-coding of events - but the display is highly inadequate. T-bird 128 calendar apparently HAS no option to color events. But events are FAR easier to see WHEN color-highlighted. Would this be a difficult option??

Like the subject says 'updated from 115 to 128.1.1esr and now (icloud) calendars wont sync'

I understand tb doesnt need tbsync anymore, do i remove these? When i try and enable the calendar function, a 'authentication required' windows opens up with username and password. But fails when the correct information is entered. I read where you can go to google, which i did, and get the required information, but that fails also.

How can I sync the new 128.1.1esr with my icloud calendars?

Thanks!

My Thunderbird profile is on a separate drive.

I had to reformat my computer. No problem with managing profile and all emails and folders, etc are ok. However, my calendar is blank!

Is the calendar not stored in your profile? Have I really lost all my dates and appointments?

I am using Thunderbird Supernova and am pretty happy with it. However, I cannot figure out how to specify a different time zone than the system timezone when creating an event. For example, if I just bought a flight that departs at 4PM London time and I am in Miami when creating the event, how can I create this event without having to convert that time to my current time?

Surely this is possible but I can't figure out how. Thanks for any help!

Please Someone help ?

I have followed all the suggestions I can find, but my Thunderbird Calendar will not sync with the Outlook Calendar on Windows 11. I am using TB Sync, but every time I try to add my Outlook Calendar ? It refuses to accept my Password, even though it is correct, and the User name and email are too ! It shows as error code 401, and cannot authenticate ?

I have tried a suggestion to create an 'App Password' to use in my Microsoft account, but the options described do not exist in my account !

Can anyone please help ?

Thunderbird version 115.12.2

How can we keep the month calendar visible in the Today Pane?

The option mentioned here seems gone: https://support.mozilla.org/en-US/questions/1420812

Thunderbird 115.6.1 (32-bit) on Win 10 and Win 11, local calendar, no email invites are sent to the listed Attendees. Correct email is entered on Calendar/Properties/Email and Notify attendees is ticked on New Event dialogue. Attendees are correctly entered under New Event/Invite Attendees. After clicking Save and Close, there is no Invitation email record in "Sent" emails and the Attendees do not receive email invitations. The event *is* saved in the originator's calendar.

The invites were correctly sent on the Win 10 PC up until TB version 113 (?), when they stopped working after the update (I think). Eventually email and calendar data were transferred to a fresh TB installation on a Win 11 PC, but the invites are still not sent.

The only difference that I can see between this non-email-invite-sending version of TB on a WIn 11 PC and another Win 10 PC where the invites are sent, is that "Troubleshooting Information/Force Email Scheduling" is set to true on the non-working version and is blank on the working one. Clues where to look next?

I have a Google Calendar, in which I manage My Tasks. I can't see my existing tasks in Thunderbird, and I can't add new tasks to the Google Calendar. New Task in Thunderbird is greyed out and the field next to it has the writing: "Please select a calendar that supports tasks".

I have seen that many had the same issue and understood that it is linked to how My Tasks in Google Calendar itself works. Is there really no workaround whatsoever?

If not, how can I manage tasks and share them with someone else (who uses Google Calendar or Apple Calendar, but does not use Thunderbird)?

Thanks in advance for your replies!

can i shut it off this way I do not gnat encryption and i am using Norton a d i also use ccleaner and glary does this have anything to do with it

I remember being able to search all calendar entries for word(s) in an event title. Is that still possible? If so, how? I can't find it under tools or the 'Search' function. TIA

Steps: 1. Setup Thunderbird with a CalDAV calendar (in my case I am using Baikal as the back-end). 2. Add (and modify) a bunch of tasks and calendar events to that CalDAV calendar, using Thunderbird and any external CalDAV tool (in my case I am using Tasks.org on my phone).

Expected behavior: The tasks and calendar events would seemlessly sync between Thunderbird and Tasks.org.

Bug:

• Tasks and calendar events added on the Tasks.org do not end up in Thunderbird.
• Tasks and calendar events added on Thunderbird, however, do end up on Tasks.org as expected.
• Tasks and calendar events modified on Tasks.org are not be synchronized to Thunderbird.
• If a modified, not synced tasks or calendar event would be modified in Thunderbird, the latter prompts ```This item has recently been changed on the server. Submitting your changes will overwrite the changes made on the server.```.
• Pressing the button "Reload all calendars and synchronize changes" has no effect.
• Toggling online and offline mode has no effect.

I copied and pasted a cell from a spreadsheet into a task and now I can't figure out how to get rid of it. There is a red box with the amount in it. I can delete the amount but the red box remains. This has been a problem for a long time and I was hoping someone had a solution. Thank you.

hi, I'm using the same TB Calendar setup for a while (3 years), in February 2024, calendar sync became erratic with showing under TB Calendar a warning : your agenda is temporarily unavailable, some events did not sync . but for the last couple of days, I'm unable to sync any events from my yahoo calendar towards TB calendar. the tbsync shows OK, reports no errors in log. could you help please , this is quite urgent matter for me. Thanks lot Phil

Dear All,

I'm moving away from proprietary platforms and am setting up Thunderbird to manage my calendars. My calendars are hosted on a Synology and synced via caldav.

Sync seems OK, but interface-wise, I cannot find a way to have my events showing their location, directly from the calendar view (even daily).Clicking on the event, the location shows, but I really need to see them directly from the day or week view (I'm a teacher, so at a glance, I need to know in which class my next lesson is).

Is there a way to set this up, or a feature to be requested?

Many thanks!

After moving from Win 10 to Win 11, I exported my TB calendar events on the Win 10 PC, and imported them on the Win 11 PC. Now I can't edit or delete the imported events. The "edit" and "delete" tasks are greyed out.

All help's appreciated
