I-Thunderbird Community Forum

I have been using Thunderbird calendar synced to gmail a/c on Linux Mint for many years and have been able to send reminder notifications by email. Recently I had to unsubscribe my calendar and reinstall to clear a fault and the notification by email function has disappeared from Thunderbird event notifications. Can you tell me how to restore that function?

Version 140.11.1esr

How do I import *.ICS file in a reasonable amount of time. I have appointments in an ics file of less than 1 K in size, typically 700 - 800 bytes in size and they take HOURS to import and do not connect properly then to allow editing the appointment. This is from Baylor Scott and White, a major hospital system in Texas. If there is a problem with the imported file structure, please point me to the correct file structure. I like Thunderbird, but this part of the calendar is very frustrating. Clarence

Hey, I'd like to switch from Outlook to Thunderbird. I’ve already tried switching to Thunderbird once when I switched to Linux, but—now to my question: The most important feature for me is being able to use different colors in the calendar to mark appointments. I wasn’t able to get this to work on Linux, even with AI. Isn’t this option available? But if people are switching away from Outlook, surely a small feature like this shouldn’t be a problem?

Can anyone help me with this?

After upgrading from Mint 21.3 to 22.3, Thunderbird no longer offers me the option of setting email alerts for events. Details: - I have Provider for Google Calendar installed - I've tried adding my calendar as "Google calendar" and "On the network" but neither offers email alerts. (On the network works better for responding to invitations.) My current work-around is to go to the google calendar app on my phone and set an email alert after creating the event in Thunderbird. That works but is a pain. This worked before. I suspect it's more a configuration issue and less a Mint version issue.

A large list of participants will extend the content of the "Edit Event" window beyond the threshold of the window, making all checkboxes (Notify attendees, etc.) and part of the list inaccessible.

This will also affect the Description and Attachments tabs.

With a lot of moving and resizing, the window can be resized to show everything, but then it extends far beyond the size of the screen. This is impractical.

The list of participants should never exceed the confines of the window and should be scrollable.

Tip for improving the calendar function of Thunderbird. It is said that the travel time that I enter in my iPhone, for an appointment is also saved in iCloud. Unfortunately, I cannot see or create this in the Thunderbird calendar. It would be nice if this were possible in a future version of Thunderbird.

Just moved to a new computer and am having trouble importing my previuos TBird calendar. From my prior computer backup (created with Macrium Reflect) I have tried moving the local.sqlite backup file to the calendar-data folder in my new TBird profile. However none of my prior calendar events have loaded into my new calendar. Is there another process or file/files I should be using? Thanks in advance. Rob W.

When I go to set a custom time for when an event's reminder will happen, it doesn't matter what date or time I put, when I click OK, it sets the date to be today, and the time to the next hour, if I use the date and time picker dropdown thing (clicking the arrow instead of typing it in), the date does set correctly, but the time is impossible to set even like that

I have been using Mozilla Thunderbird for many years on Windows desktop (now Win 11 ver 24H2 for x64 based systems).

In the last week or two Thunderbird has been giving me unwanted reminders for future events on my Google Calendar. (They are Thunderbird reminders, since they disappear when closing Thunderbird). If I try to dismiss them I get an Error Code: Modification failed. Status Code: 2,147,500,037, null Server Replied with 400

Dr google suggestions to get rid of them only apply to iOS or Android, nothing mentions windows. The problem does not occur on my iPhone.

If I just close the reminder windows they reappear in a few minutes.

I uninstalled and reloaded to be sure I had the latest Thunderbird.

I have my calendar from mailbox.org synchronized with my thunderbird via CardDav/CalDav. I have multiple calendars in the same account (e.g. work, free time, brithdays, ...). I cannot change in which calendar an event is saved after I created it.

How to reproduce: Edit an allready existing event and change its calendar (e.g. from "free time" to my "work" calendar).

Expected behaviour: The edited event is now moved to the other calendar.

Observed behaviour: The event is not moved (any other changes to the event are saved though).

It is not the fault of my provider as it works on my phone and on their web app.

This is either a bug in any of two ways:

• It does not change calendars events but it should.
• You are not supposed to be able to change the calendar afterwards and that means the selection of the calendars should be grayed out/ give you no option to save it.

(I know I can Ctrl+X and Ctrl+V it into a diffferent calendar, which I use at moment but that costs additional time.)

Thanks for any help with this :)

PS: I have to choose a topic but the calendar is not even part of that list. What is going on there?

It seems lately that when I simply open a calendar entry to see what the contents are, then close it without making any changes, it sends an update to all those involved that something changed (as seen in the picture).

Also, when I accept an invite event and tell it not to send a response, it always does. This has been happening for as long as I can remember, and I cannot figure out a way to stop it, no matter what I do.

Anyone have any ideas for either of these issues?

Bisherige Ativitäten: Versuche einen Google-Geburtstagskalender Kalender zu nutzen -> nicht funktioniert Versuche einen Mozilla-Geburtstagskalender einzurichten -> nicht funktioniert

Ich vemute, dass die entsprechenen Kalender keine entsprechenden Daten finden?!

Thunderbird und die Adressdaten stammen aus der gleichen Version wurden aber von einem anderen Windowsgerät unter Windows 10 übertragen/übernommen!V

Problem with recurring events in the caldav (external) calendar. If you delete one instance of an event (today), events for previous days are automatically created.

Thunderbird ver. 140.7
