How does one enable calendars in Thunderbird version 115.8.0? When I click the calendar icon on the left of the page, I get a calendar displayed but it has a message highlighted in yellow that says: "All calendars are currently disabled. Enable an existing calendar or add a new one to create or add events."

I cannot find anything in settings or elsewhere to enable calendars.

TIA

I just subscribed to the US Holidays calendar on the TB Holidays page: https://www.thunderbird.net/en-US/calendar/holidays/ -> https://www.thunderbird.net/media/caldata/autogen/United-States-Holidays.ics

I noticed that Memorial Day is missing for all the years included in the calendar. I just ran across it, so I haven't looked thoroughly.

Is there a way to report this to someone or to correct it and submit a corrected version?

Thanks!

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.

I've just upgraded from TB 91 to TB 115 and unfortunately all my 'local' calendars are missing and I cannot add them back either. By local I mean 'On My Computer'. There is no problem with my 'On The Network' calendars, both existing and new ones can be added. But when I click New Calendar > On My Computer > (fill in name) > Create Calendar... nothing happens... no new calendar appears.

Hallo, i've updated my Thunderbird to 91.8.1 on my Kubuntu 18.04 Lini9x machine. I have some *.ics files attached as calendars via ftp (ftp://192.168.1.1/Kalender/xxx.ics). After the update Thunderbird/Lightning tries to open them in firefox.

Every time Thunderbird/Lightning syncronises the calendars, different tabs occur in Firefox trying to open the files. Thanks a lot in advance, Gruß

The answer I found is pretty obvious, one has to search at "Options/Calendar/Categories".

But where do I find the "Calendar" section? Even using the search engine on the option page doesn't show any results.

Very frustrating... A picture of the location would be very helpful.

So. Thunderbird released an update, I updated, and all my custom event colours, that I really need, have gone from old to current see attachments. This was asked https://support.mozilla.org/en-US/questions/1326997?utm_campaign=questions-reply#question-reply

And a solution found that worked. Now Mozilla in their ludicrous wisdom have somehow screwed this up again. Anyone have a solution that works? I and lots of other people like the whole event title bar being a single colour. These 'dots' at the end are useless to see. Thanks PS Stop screwing with the settings. What to add something new, then create an add-on.

When I opened the Thunderbird Calendar this morning 99% of information, appointments, meetings, birthdays, etc. are missing. The Monthly view shows one or two events, the rest of the days are blank.

I've used thunderbird with gmx calendar for many years. Apart from persistently forgetting its "stored" password, I've never had any problems.

But about a month ago, I started getting a message that the servier wants to redirect from the usually-correct https://calendar.gmx.com/begenda/dav/[my name]@gmx.com/calendar to gmx.com.

At first I didn't accept the redirection, but the calendar stopped syncing. Then when I did accept the redirection, the calendar disabled itself altogether. Using the ENABLE button didin't help.

The GMX calendar itself is working fine:

• I can access by logging in at gmx.com and the organiser tab
• the calendar still works fine via my lineageOS phone
• if I go to https://calendar.gmx.com/begenda/dav/[my name]@gmx.com/calendar while still logged in, I can download a raw list of all of my events

GMX support suggested removing the calendar from firefox, changing the password on gmx and adding it up again. Mostly it was not possible to add it, with thunderbird giving the message:

https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-04-16-00-57-44-0e6dec.png

That long location is the location suggested as correct in gmx thunderbird FAQ. But I also tried setting the location as gmx.com or caldav.gmx.com with the same result.

Eventually after trying on numerous occasions I managed to add the calendar again, but in less than a day I was back to getting the redirect message and the calendar not syncing.

I've removed the gmx calendar, reinstalled thunderbird and tried to add the calendar again. At the moment it will not add using any of the locations mentioned above. But of course, I can still access it via gmx.com and my lineageOS mobile.

Also tried adding with thunderbird in troubleshooting mode but no difference.

I subsequently tried two suggested addons (now disabled because they did not help):

https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-04-16-01-13-26-d28ffe.png

• Thunderbird help says 91.8.0 and it's running on windows 10 64 bit.
• I don't have any caldav-related addons (nor did I need any in the many years when gmx calandar was working properly in thunderbird

I do have these addons (but the troubleshooting mode test should have eliminated them)

https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-04-16-01-19-55-b59057.png

What to try next? I'm only interested in the calendar, not gmx email and I'd prefer to see my calendar in thunderbird than at gmx.com

I am evaluating TB and the integrated calendar. I had no problem installing mail and calendar in terms of synching, mailing, and receiving except one: The calendar page will not refresh unless I hit the Hide/Show eye icon next to the calendar. Sometimes it also shows if I toggle from Today to Week.

Calendar properties do not show any options at the bottom for refresh cycles (see attachment). Other specs are below.

This is a show stopper for me, since appointments that were transferred but not showing are of no use. Please advise.

Thanks, Michael Clifford Details below

TB Synch - Periodic Synch set to 1 minute Win 10 Home Imap Mail Server outlook.office365.com checks for msgs every 3 minutes TB 91.9.0 (64-bit) Provider for Exchange ActiveSync

Today, I noticed that I can no longer get to the Calendar & Task Tabs in my TBird 91.9.0 running in Win 11 Insider Beta Channel. In View, both Calendar & Tasks are grayed out (see pic). The Today Pane does display events, but no tasks.

I created a new profile, but things are worse…there are no selections for Calendar or Tasks in View. I followed the instructions about deleting the extensions.installedAddOn… and restarting, but no luck.

Unfortunately, I don't know when it broke. I did install 91.9.0 recently, but I didn't notice if Calendar was working. The Today pane has been working, though.

This is working on my two Win 10 systems, both also at 91.9.0.

I'm pretty technical, so no need to edit.

My calendar is suddenly a day behind on all of its dates, and the time for adding an item to the calendar is off by an hour. Is this just my computer (MacBook Air), or are others having this problem too?

I am using Thunderbird 91.9.1. I have imported several calendars from my google account which works really well. What does not work well is trying to import/show my google tasks, they simply appear nowhere. How I tried to import them: Calendar -> New Calendar... -> On the Network -> Entering my google account at Username -> after logging in, only my google calendars are shown, not the tasks.

What am I missing? Thanks!

Hi all and thanks in advance.

When accepting an appointment/import ics I get the error in the error console

Calendar: Couldn't find Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna

The meeting is sended from Outlook for Mac. I use Thunderbird 91 on Ubuntu 20.04

Content of the ics file: BEGIN:VTIMEZONE TZID:Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna X-ENTOURAGE-CFTIMEZONE:Europe/Amsterdam X-ENTOURAGE-TZID:9 BEGIN:STANDARD

My current time zone in the setting is: Europe/Amsterdam

Any suggestions to be able to accept the meeting?

Cheers!

When I try to import an ics file into the Calendar I receive a message "Cannot import from Downloads/appointment.ics. There are no importable items in this file." I found some articles where the line endings were not correct, I checked they are OK. I checked for invalid characters, there are none. So how I import the ICS file? What is not correct in the file? The file is: BEGIN:VCALENDAR VERSION:2.0 PRODID:-//Sabre//Sabre VObject 4.3.3//EN CALSCALE:GREGORIAN BEGIN:VEVENT UID:sabre-vobject-40eef33e-ae8f-4ebd-bae1-1e7f9b11a28f DTSTAMP:20220603T193644Z SUMMARY:Appointment - mymeeting DTSTART:20220707T133000Z DTEND:20220707T140000Z LOCATION:6875 Bd Rue Mycity Canada ORGANIZER;CN=1: ATTENDEE;CN=1: END:VEVENT END:VCALENDAR

Thunderbird 91.10.0 (32-bit), Windows 11. My PC went to sleep as normal while I was out for a few hours. When I returned and woke it up to check my emails I noticed the Thunderbird Calendar had gone - just the Inbox is there. In the View menu Calendar and Tasks are greyed out. The Calendar is stand-alone on the PC, not synched anywhere. I had put a couple of new Calendar entries in earlier, everything looked fine. No updates, installs or uninstalls before this happened. A Bitdefender scan says my system is clean. Email seems to be working fine. I have reached the limit of my technical abilities, any suggestions please?
