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

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.

It seems that this guide does not work anymore: https://support.mozilla.org/en-US/kb/adding-a-holiday-calendar

The point 5 ("From the Format list, select iCalendar (ICS).") is not there anymore. The wizard shows directly a form where you can enter the "Location", but if you enter the URL of an ICS file, it says "Could not find calendars at this location. Please check your settings."

Is there a different way to add these calendars? (and any other ics calendar you can find on the web)

Thanks

I'm not sure when this started happening but Thunderbird (115.3.1, Linux) is no longer sending email invites to my invitees, even if some of those invitees are on my same host. as "Organizer" I do get an email notice to my personal email, which is the default attendee, with subject "Accepted: testing", and body, "mfoley@novatec-inc.com has accepted your event invitation.", but nothing is sent to the other invitees on the list. I checked the error console which showed these messages after I created the event:

NotFoundError: No such JSWindowActor 'DevToolsFrame' 6

1701371572264 Toolkit.Telemetry WARN TelemetryStorage::_scanArchive - have seen this id before: 9c1e2d46-28f9-430d-86d7-398dd0ad3bdc, overwrite: false

mailnews.smtp: error { target: TCPSocket, isTrusted: true, name: "NetworkTimeoutError", message: "Network", errorCode: 2152398862, srcElement: TCPSocket, currentTarget: TCPSocket, eventPhase: 2, bubbles: false, cancelable: false, … } SmtpClient.jsm:442:17

Not sure these apply to creating a calendar event. My server settings are fine, I can send and receive mail to the Thunderbird inbox without problem. I can send email from the Thunderbird client without problem.

Any idea why I can't send event notifications to invitees?

Hi All,

Need help with linking a file to a calendar reminder (event).

In Outlook I used to be able to easily link a local file located in a specified folder on my computer. For eg: I would link a .pdf invoice for my electricity bill in a folder on my computer. I would create the event to remind me I had to pay this invoice and after creating the reminder link that PDF invoice to the event and when I clicked on it, it would open the invoice using Acrobat reader or whatever other PDF reader I assigned.

I tried to attach the link using the "website" attachment tab to the event in T'bird calendar and assigned Acrobat to open the file (invoice). Acrobat does open, but returns an error saying it can't find the .pdf file. The file is definitely in the nominated folder and the link to it is correct but file doesn't open. Anyone know what I'm doing wrong?

Any assistance much appreciated. Thank You

Attempting to add birthdates to Thunderbird calendar. Have initialized 'Lightning' and 'Provider for Google' addons. Existing calendars appear to be synced. That is, I can add events in Thunderbird, and they are visible in my Google calendar (and visa versa). Wish to add a new calendar for birthdates using the 'Birthday Calendar' addon. 'Birthday Calendar' displays birthdates pulled from 'Address Book', and has the added desirable feature of calculating/including 'age'. Thunderbird appears to be correctly retrieving birthdates from 'Address Book'. However, these new birthdate calendar entries do not seem to be reflected in my Google calendar. I do not see an option (in Google) to add this calendar. Can someone guide me through the process of connecting this new 'Birthday Calendar' with Google?

I added the United States Holiday Calendar to my Thunderbird Calendar.

As it has zilliions more holidays than I care to see (World Pneumonia Day, for example) I would like to remove it. I added it as an internet supplied calendar, not stored on my computer.

Can someone please tell me how to remove it entirely? Also, is there a different, more modest calendar I might add somewhere out there?

Thanks in advance for the assistance. I have searched for a way to do this but have not found anything.

After upgrading Thunderbird client to version 114.4.1 on my Windows 10 computer, I no longer can see events. I am using a CalDAV server on Linux. I believe creating and updating events works on a different Linux client, but not on this Windows 10 client. In my error console I see the message, "Calendar: Could not find definition for Eastern Standard Time". I've read some posts where others had that same time zone issue and fixing that got their events to show up. Unfortunately, they did say how they fixed it. Perhaps that is my problem as well. How do I resolve this error (to start with)?

I updated to the new Thunderbird 115. I imported my folders etc with no issue with only 1 little problem - my local folders are in between my 2 email accounts and I can't seem to move it down but not a big deal.

The real problem is my calendar events. I had a very full calendar and after the update, my calendar is empty and blank. I have no idea what to do. Everything else imported fine. The calendar is the only calendar I use. Hope someone can help.

Thank you Norma

I cannot see the description for a lot of the events in my calendar when there are large attendee lists. In this example the attendee list is so large I cannot even resize it to see the description. There needs to be a way to scroll the event window as a whole when the content doesn't all fit, or alternatively a way of collapsing the attendee list.

I now have two issues, one is that on my IMAP accounts with my own domain, both the recent sent and recent received emails in a thread are showing up twice. This doesn't happen with previous emails in that thread or with gmail, exchange, outlook.com, live.com, icloud, etc.... Now, I have an issue where the pop ups for calendar notifications keep popping up non stop and either won't go away by hitting "Submit to changes anyway" or if they do go away, they immediately pop back up again. 115 is a big disapointment for me, it's been highly glitchy, many add ons no longer, some that should work, don't work properly, it was hyped a major upgrade and I see very little that distinguishes if from 102 in any meaningful way except some of the icons are more colorful. Is there a way to go back to 102? Either that or I may start using Mac Mail again due to all these bugs.

After Upgrading to SuperNova (115.3.1) My caledar view just explode... I need like two 25"" monitors to get one week view as one. The columns just turn HUGE and cannot find a way to set them back to a viewable size. is there a way to fix this? Please your help and advice.

In Supernova (i.e. Thunderbird 115 and above), the mini-month calendar shows a little blue dot under every day that has an event on it. See the example screenshot.

If you're like me and you have an event almost every day, then these dots don't really provide any informational content – they're just visual clutter.

There is a way to remove them, using userChrome.css:

   .minimonth-day::after {
       display: none !important;
   }

But obviously that's not so good for users who aren't adept in CSS. Is there a way to remove the dots through a preference, or something in about:config?

Please, explain me, what does the "wrench" icon means? I have some events, which I do not receive notifications from. And these events are marked by the "wrench" icon.

Hello,

Just started using Thunderbird for its calendar, but I can't find the settings for Calendar Events. I am aware that I can select a specific calendar and go to its Properties Window, but I want to access the app's settings for all calendars. Research shows that there should be a Calendar tab in the app's settings tab, but it isn't there for me. I only have the General, Composition, Privacy & Security, and Chat tabs. Can someone please help me get this tab to appear?

Thanks!

The Today Pane is showing no events. The events show fine in the Calendar mode, but not in the Today Pane when set to Events.

I tried using Troubleshoot mode and it made no difference.

I have version Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:102.0) Gecko/20100101 Thunderbird/102.15.1

Right clicking anywhere in the Events area of the Today Pane does nothing at all. Right clicking in the Tasks area does show a menu, but nothing in the menu has anything to do with Events.
