When scheduling on Calendar, it is set to "Contacts," and I have to manually click on that box and change it to my e-mail each time I schedule something. I can't find how to make my e-mail the default. Help?

Given that I want to create a new event in the calendar with a description When I click on +New Event Then a tab opens that is so large given my 175% scaling that the Description field for the New Event is just above the taskbar. I cannot see what I am typing beyond the first line. There is no scrollbar to scroll down, nor a way to collapse the fields above.

=> This design is inadequate for 30% of the world population that suffers from presbyopia, or age related poor sight, and uses a large scaling.

Hi, I am using Thunderbird for years and this issue started to happen last week.

I am using a Teamup calendar as an external (readonly) calendar, this is the URI: https://ics.teamup.com/feed/ksrcmy4ajs6stupbg6/5826514.ics

Apparently, from last week when it is enabled, Thunderbird needs about an hour to start and memory rises to 3 GB. I tried older TB versions while I was investigating what is the issue with the strange behavior, from TB ver. 102 and later, but it is the same. At the end I found what was causing this memory consumption and startup slowness and I disabled the calendar and TB works well.

If you follow the link and download ics file it seams ok, it imports to other calendars lika Outlook, Calendar etc. easily.

Please investigate and update and I will send any additional info if needed.

Best regards, Vladimir

Hi,

I recently installed a CalDAV server at my workplace to connect to in the Thunderbird calendar, as we all already use Thunderbird for e-mail.

If I create a meeting in the calendar and invite everyone else, they all get an email invite with the name, time & place of meeting etc.. And at the top of the email, just below the title of the email, there is a purple bar with boxes saying "Accept", "Tentative", "Deny" and "More" (or something synonymous, I have it in Swedish).

For one employee that purple bar with the "Accept"-box does not appear, and the only way for him to get the meeting to his calendar is by downloading the "invite.ics" file that is attached and importing it afterwards.

I have added two screenshots showing what I mean. One with the Accept, Deny etc. and the one person's e-mail that doesn't have the boxes.

We have checked his settings without finding anything that seems wrong in first glance. I have checked the caldav user account but the user account has the same settings as the others. Thunderbird is updated to the latest version (115.7.0, same as I use and it works for me).

When he invites people to a meeting they all get the invite correctly, so nothing is wrong when he creates a meeting invitation, only when he recieves an invite.

What could be wrong? Is there a setting he might've activated/deactivated in Thunderbird that we missed when looking or could there be something else we have thought of?

Thanks, Tim

It has been about a week now since 115.8 tried to install on my Windows 10 but could not without my password. I have been on Auto update for years now and could not put in correct password. It was suggested I go back to 102 and start over with a new account. I did. I have 102 and can send and receive emails. Problem is 102 does not show all emails that show in my same account when I log into Ionos.com host of my email account. I created another problem going to Thunderbird 102, birthdays. I have no access to my Thunderbird calendar not only for this month but all months this year and forever. I made a copy of everything in my account prior to going back to 102 to get a new password. How to I get my 2014 calendar back. And first thing I do if and when I get it back is to use a pen and paper to write down birthdays and whatever I want to remember and save it on paper just in case this happens again? Thanks.

Hi. I just started to use thunderbirdb calendar and I'm a bit confused about 'Tags.' Should I be able to add a tag to a new event or task? If so I see no option to assign a tag to an event or task.

How do I distinguish between an event and task?

Thanks, James

Hi

I am unable to access my old calendar details after moving to google calendar. I had entries in calendar prior to dec 2016 that if possible I would like to retrieve. I backed up a copy on 070717 including email address book and calendar. I have the files on my hard drive. There is a folder called calendar-data with cache info in it but when I click on it it says to open in microsoft store? How do I access them now in Thunderbird calendar I have the latest thunderbird version 115.7.0 64bit

would appreciate your support Brad

While trying to import a .ics into thunderbird calendar an error occurs:

"Beim Schreiben in den Kalender Privat ist ein Fehler aufgetreten! Weitere Informationen stehen weiter unten." "Fehlercode: MODIFICATION_FAILED" "Beschreibung: Falls diese Nachricht nach dem Verwenden von "Zurückstellen" oder "Schließen" für eine Erinnerung angezeigt wird, aber Sie für diesen Kalender keine Termine hinzufügen oder bearbeiten wollen, so können Sie diesen Kalender als schreibgeschützt markieren, um diese Mitteilung nicht mehr angezeigt zu bekommen. Klicken Sie dazu mit der rechten Maustaste auf den Kalender in der Kalenderliste der Termin- oder Aufgabenansicht und öffnen Sie die Eigenschaften."

The .ics file was generated by calendar export from Thunderbird version 115.6.0 and the import is also being done with the same TB version. OS: Linux Mint 21.3 Virginia

I can import the .ics into other calendar software without problems, so it doesn't seem to be damaged.

Hi!

We found an issue with import cancelled recurrence .ics events which affected by caldav import also.

Steps to reproduce (simple version without caldav server)

1. Create recurrence event with one participant
2. Delete/cancel one event from recurrence with notify participant
3. Download received event of cancellation
4. Try to import this event to the Thunderbird calendar

Issue caused by:

• The problematic line is: "RECURRENCE-ID;TZID=Europe/Berlin:20240208T140000"

If i delete this line, the import works as expected.

Can you help with this?

Thanks! BR, Z

When I double-click on an event in my TB Lightning calendar, the event details window/popup/whatever-you-call-it opens up at a fixed size which 90% of the time is too short vertically to see the Edit button. This forces me to have to resize it manually just to be able to click on Edit. This is making the calendar very annoying to do. Any of the following might help:

1. How can I change the default popup window size?
2. How can I make the manually selected size sticky?
3. Can you change the default size to automatically be tall enough for the Edit button to be visible?

Thanks for your help

Hello,

Similarly to user that asked https://support.mozilla.org/en-US/questions/1376333, I would like to know if an accepted event can be edited – really edited, not just by converting/duplicating it to a task or another event.

For example, if I added an accepted invite to the wrong calendar and would like to move it to another one of my calendars... This calendar switching feature is part of MacOS Calendar, even if, as in Thunderbird, other properties of an accepted invite are not editable (except for comments).

Since this lack of control over invite edition is mainly what is holding me to adopt Thunderbird, is such a feature likely to be deployed eventually?

Regards,

Ever since the latest 115.8.0 update local links to .pdf file stopped working eg: below. When I would click on that link it would open the invoice.pdf in my PDF client.

file:///D:/%20Internet%20Services/%20Feb%20invoice.pdf

Hoping whatever was broken will be fixed soon Thank You

Calendar print shows two items where only one exists. See attachments of both the original Google Calendar and the TB calendar prints. If only one of the calendars is selected, the print is correct

I use Thunderbird calendar for all my events and without it I am lost. Yesterday, I wanted to export my calendar to be imported later by an online platform. I used the export function. I noticed however, that under the name of my calendar on the left pane this has appeared ( . export). I thought the ics file is already created, so I went ahead and deleted the strange ". export" item that appeared under my calendar name in the left pane. What happened next was that all my events disappeared from my normal calendar window. My question is how I can get back all my events? Or how I can restore the ". export" so my events come back.

Additional information: I did not have backup for my calendar. I cannot locate anywhere the ics file I thought it is "exported" I am using the latest version of Thunderbird as of March 2024.

Prior to recent updates my calendar laid out the windows so that I could see the events without issue. With one of the updates (I'm not sure which) my calendar has the hourly window covering my events. I've attached photos of both, but it's rather annoying to have to change it manually every time I open the program.

I've tried changing all the settings I can think of to remedy this and even removed my theme in case that was it, but none of that worked.

Is there a way for me to fix this that I missed or am I stuck with this nonsense?

Thanks!

A few daysa ago, my calendar stopped syncing. I tried re-entering my creds, no help. I removed and re-added my account to TBSync, again, no help. I even tried changing servers. TBsync says use eas.outlook.com, Microsoft says use outlook.office365.com. I jet a 401 error either way. I am open to suggestions.

I have a website from which I can download a calendar as an ics file which I'd like to import. Initially this works OK. However, sometimes this website calendar is amended and I'd like to be able to update my Thunderbird calendar but a subsequent import fails completely if it includes an update to an existing entry. I know that the UID of an event in the ics file matches that of an existing Thunderbird entry but the LAST-MODIFIED value is later in the second ics file entry. Is there any other condition that should be required to allow the import to run and update any matching existing entries? Any ideas welcome. CrowboroughChris

I am affected by this bug in Thunderbird 115.6.0 on Debian Linux (KDE xorg) so I cannot currently use two-finger touchpad scrolling to navigate without flying months into the future or past. On top of that, there is no visible scrollbar and it is not even responding to the keyboard arrow keys or PgUp/PgDn when the focus is on the main calendar. Any idea how to get this working? This is making it pretty impossible to get around when I'm not using a mouse with scroll wheel.

Thunderbird 113 (?), local calendar, Win 10, email invites stopped being sent to the listed Attendees. Correct email was entered on Calendar/Properties/Email and Notify attendees was ticked in New Event dialogue. Attendees were correctly entered under New Event/Invite Attendees but after clicking Save and Close, there was no Invitation email record in "Sent" emails and no Attendees receives email invitations. The event was correctly saved in the originator's calendar.

TB 115.7.0 installed from scratch on a new Win 11 PC and the emails/calendar data transferred from the old PC. Everything works *except* that no invitation emails are still sent to the listed Attendees of a new event (same symptoms as on the Win 10 PC). So transferring emails and calendar entries transferred the problem to the new PC.

What next?
