For many years I have been printing each month with all dated information. I use that info to manage my life and meetings. The new version 115.3.3 (64 bit) will not allow me to print a month. What do I have to do to print what I need?

Hi, I'm trying to figure out what is the correct procedure (if any) for migrating calendar/task data between different profiles WITHOUT using the UI (since upgrading to version 115, Thunderbird's UI became irresponsive when started with my existing profile , so I'm no longer be able to access my data nor to trigger the export procedure via the UI.

Can anyone point me to the right direction?

Thanks in advance for any answer.

Hello I am having issues with my calendar option not retaining the events that I have entered. I have never had this issue before. I have no clue how to get it to retain the entered events. Any direction would be greatly appreciated. Thank you! Monique

Is there any way to get of duplicate scheduled items in the Calendar? Everything is duplicated! I'm not sure how they got there but it might have happened when I was trying to fix a differenct problem. Can I disconnect from the Google Calendar then reconnect?

So I was having problems changing an event to a different day. I performed an update, restarted, recheck updates, restarted PC Open thunderbird, mail appears Okay, calendar Okay Still cannot change an event (appointment) and it has lost the last appointment I added yesterday I decided to just add the adjusted even as a new event, and all calendars (2023, 2024, Holidays, birthdays) all now blank, and .ics fils are all 4.0 kb Seriously what has happened. Was working 3 days ago perfectly, now it's "stuffed". 1. Calendar is Blank 2. Cannot add anything new 3. creating a new calendar (restored from backup) is BLANK -Any suggestions? PLEASE

I use Calendly.com for scheduling my meetings. I'll receive a meeting confirmation email when someone books, and linked from that email is an .ics file I can import to Thunderbird calendar. This all works fine except that meetings imported don't respect the default reminder setting. No reminder is set at all for these meetings - I have to edit each event manually to append the reminder to match what I have saved in the Reminder Defaults section of Settings (15 mins).

Meetings added to my calendar in other ways (i.e. an invitation direct to my inbox) respect and apply the 15min default. This places the blame on Calendly so I looked at the .ics files I'm getting from there and find no TRIGGER reference at all. I imported an unrelated sample .ics file with the TRIGGER explicitly defined and this works, but in the absence of a TRIGGER reference in the Calendly files, my expectation is that the default reminder time would be applied.

Any advice on what may be happening?

Thanks

I recently updated to Thunderbird 115.6.0 on Linux. After doing so I can no longer add events to my calendar. In the error console I get the message, "An error occurred when writing to the calendar ... Could not find definition for Eastern Standard Time". This seems like a rather odd error. How do I fix it?

Hello everyone,

First of all I would like to say that I love Thunderbird! I am also not very IT literate when it comes to manipulating software or using the correct language so please bear with me, I find these a bit overwhelming.

I was hoping someone could help me with with my calendar, I have tried to change settings on other software and it went terribly wrong and I don't want a repeat. I have read the various help files but it doesn't make much sense to me :(

I have a domain with Dynadot for my website and email, it's basic but does the job for my small business. It has IMAP abilities and an autoreply but that's about it- there's no calendar app but does have an email app... just. On my Windows laptop I use Thunderbird for all emails and calendar requirements which is great when I'm using my laptop. However, I do meet with participants and don't always use my laptop so I need a way to be able to view and book appointments using my andriod phone.

I also have a member of staff who needs access to my calendar and be able to book appointments for me and vice versa. As we are both out and about a lot the calendars need to be "live" and easy to reach, much like the paid for Outlook shared calendar.

At the moment my member of staff doesn't use Thunderbird as their main software, they have Outlook. We did try another email/calendar app but their shared calendars were just links that we had to save and keep logging into, it was a nightmare and without the updating we had some double-bookings. I don't want to go through that again, it was embarassing.

I would greatly appreiciate your wisdom in how I can resolve my issue and easy step by step guidance on how to do it properly. I am the type of person who will get locked out of everything!

Best wishes Rebecca

In every version from 118 beta to the latest, the Calendar View Events filter option is limited to max 1 year. In previous versions, there was a filter option to view All events. I need this option in filter to be re-instated because 1 year is not enough. I want to see all events to manage my calendar more effectively.

Specific 'Calendar' topic, but could also be considered to be about updating (improving) the Thunderbird controls/options/addons.

Is this a Feature Request, per say? If so, is it in the right place here? If not, where to put this?

Platform: Windows 10. Issue: Thunderbird (Lightning/Calendar) keeps aggressively stealing focus, i.e. putting the Reminder window on top of whatever else I am doing. This is incredibly annoying and unproductive. The only option is to completely disable Reminders, which defeats the purpose of course. See also, for example, https://www.reddit.com/r/Thunderbird/comments/185c727/how_can_i_prevent_the_reminders_window_from/. Requirement: I would like to still hear the Reminder sound, and it would be great if the application also 'gets highlighted' (in orange) on the Taskbar (like many applications that have something new going on, but do not immediately push themselves to the foreground) to get a visual Notification, as well.

In any case, this overly dominant behaviour of the application should NOT persist.

Thunderbird 115.6.0 (64-Bit) is no longer syncing with Google Calendar.

I do not know since when, but recently added dates in Google Calendar are not show in Thunderbird calendar and vice versa. 

I've tried to setup new connection between Thunderbird and Google, this seems to work, because I got question on smartphone (authenticator app) to allow new connection. But the dates are still not synced. Even forcing sync does not do anything. Same things happens on two Windows 10 64bit computers, but also on Linux Mint. Any advice? Thanks.

if I schedule a meeting locally for 9am some attendees receive the meeting scheduled at 8am (1 hour earlier than actual). I have checked my thunderbird date and time settings and they are correct. The attendees claim their settings are correct but between the 2 systems (Thunderbird and Outlook) there is an hour discrepancy. This is causing clients to miss my meetings. Please assist.

I installed the beta version of Thunderbird without realizing it's incredibly difficult to switch back to stable, so I'm stuck with beta. In beta, can someone explain the reasoning to me behind why calendar shows a view-only window when double clicking an event title instead of going directly to the editing window? It was so much easier to edit events before:

double click the title > start editing

Now, in beta, both ways to edit an event require extra steps:

right click title > click edit > scale the window larger > start editing or

double click title > scale the window larger > click edit > scale the window larger again > start editing.

It doesn't make any sense. I can't think of any reason for having two separate window states for an event - you don't need a display view and an edit view, because they both display the same information. Just have it open directly into the edit view like it used to.

I made a video to attach but it doesn't allow videos. Let me know if I can provide something else instead.

Windows 10 64bit Pro Thunderbird SUPERNOVA 122.0b1 (64-bit)

Hello, Does anyone know how I can get a calendar event reminder via email? When editing a calendar event, I click the reminder dropdown box and select "custom", and the only option I have for "Choose a reminder action" is "Show an alert" (see screenshot).

I'm using Thunderbird 115.6.0 (64-bit) on Windows 11, freshly installed with a few email accounts and a Gmail calendar. Everything else seem to sync and work fine. I unsubscribed\resubscribed to the calendar to no effect.

I used to have 3 calendars. now everything shows in one calendar named 'calendar'. how do I get to display one calendar at a time. In the current display under column 'calendar, name' I see 3 different names and the items in the display are pink, green, and yellow. I think at some time I hit 'synchronize' by mistake.

Thanks for your help.

I am running Ubuntu 22.04 and Thunderbird 115.4.1 (64-bit).

I am a long time user of both Ubuntu and TB.

For years, I have had calendars working with TB (& Lightning).

I use a number of sources, but I am trying to slowly migrate to having one set on my phone and computer, which means using iCal.

This has worked seamlessly for years, but it now isn't working on my main laptop.

I have had to set up the iCal calendars twice, as one implementation allows me to setup an event, but won't show it, and the other shows the event, but won't let me set it up.

Both ways are configured as R/W.

That is painful, but almost tolerable, but the main issue is that the iCal calendars don't show any reminders.

On the phone, they are visible, and enabled and work.

Other calendars (not iCal) seem to work OK - but that isn't fully tested.

I used the route to set up the calendars as described in https://frightanic.com/apple-mac/thunderbird-icloud-calendar-sync/ - and didn't use any scripts but configured them manually.

There are three iCal calendars (I have no idea why, but ...)

I have named the three calendars on the computer e.g. CalA1, CalA2 and CalA3 - and the "duplicate" ones CalB1, CalB2, CalB3.

One thing I have puzzled over, is that the "server number" between the "CalAx" and "CalBx" are different, but constant within CalAs and CalBx.

I tried setting up a new instance, but Lightning would not allow me, even though the URLs were different.

However, CalAx all allow me to set events including reminders, but doesn't display them.

All CalBx won't allow me to set up or edit events (providing an error on saving).

In both instances, the calendars are enabled, and are set to be R/W.

My ideal would be to have either CalAx or CalBx working with reminders - so it is less confusing for me! But it is the reminders that is my greatest bugbear!

Any help would be most appreciated.

Many thanks,

I'm using an old, no longer supported add-on called Reminderfox that saves its contents in ics format. I used to be able to import this to Google calendar and Thunderbird but for some reason they and also Microsoft Outlook won't now import the ics file. They either give an error as in Thunderbird's case (error, no items to import) or just remain greyed out so I can't do anything else as in Google and Microsoft's case. I have submitted the ics file to an ics verifier online and it says there are no errors. I have also looked at the file in notepad and can't see any obvious errors, although I'm not fully conversant with the ics format. Can anyone suggest what the problem might be or anything else I can try please?

This morning there was an update to Thunderbird. When I reopen the program I can no longer see the right end of the screen. There is no toolbar to scroll over to see that side, and I've been unable to resolve this in the settings. I am using Density > Compact and I do not have any add-ons installed. See screen capture. I will have to stop using TB if this can't be resolved.

Hi,

I have several individuals stored in my Contacts for whom I've loaded their birthdates. I would like to receive reminders and/notifications in Thunderbird when these birthdates are approaching, say like 10 days out. Is there a way to configure Contacts and/or Calendar to get these reminders/notifications in advance of these birthdates? If so, how?

thanks, Tom

I'm not sure exactly when it happened, but pretty recently, my calendar started showing 6 weeks (in 6 rows) instead of less (I think it was 4).

How do I show less weeks at once (so more of each day's pane is bigger and shows more of itself), like it used to be?

I have Thunderbird for Mac v 115.6.0

Thanks, Ted
