Thunderbird Support Forum

I am using Thunderbird Supernova and am pretty happy with it. However, I cannot figure out how to specify a different time zone than the system timezone when creating an event. For example, if I just bought a flight that departs at 4PM London time and I am in Miami when creating the event, how can I create this event without having to convert that time to my current time?

Surely this is possible but I can't figure out how. Thanks for any help!

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.

Hello, I've had massive problems with it since the update to Thunderbird 102 and the migration of the Google calendar directly into Thunderbird. Appointments are not created, I cannot write an appointment description or it is not saved and transferred. Often an exclamation mark appears after the calendar name in the calendar overview, it is not synchronized - unfortunately it is so very difficult to work with it - or otherwise, even almost impossible. Are there other reports with problems in this direction or is it my system and the settings? I would be very happy about help or tips, many thanks and best regards Ps. is the help also available in German?

Have just been updated to v102.2.2 and now my events are invisible in the weekly calendar view, though they are visible in the multiweek view. Also reminders are not being actioned.

Can anyone solve this please?

I'm using Windows 11 on a Dell Inspiron.

In or around TB 91.3.1 double-clicking on an event, you get a dialog box such as the attached. In order to edit the event, you have to hit the Edit button. In the past, TB would just open the event and allow you to edit it. If the event was recurring then, and only then, would a small dialog box come up to ask if you were editing just this event or all events. I see no advantage to this extra dialog box, especially for one-time-only events. It's just another unnecessary click of the mouse.

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.

TB 102.5.1 (64-Bit), Windows 10 When I want to add a new date or change an existing one, the window does not pop up. However, hovering over the TB taskbar icon, I can see the window as a thumbnail. Very annoying bug, I believe was introduced with the 102.5.1 release.

Dear all, I have a couple of calendars on the disk as network calendars (file:///...ics) with offline support, and I just realized that I cannot delete any event. These calendars are not read-only, I can see the option delete, both with right-click on the event and double-click to edit the event, but after pressing delete, the event remains on the calendar. Just pressing the delete button on the keyboard after selecting the event has the same behaviour. If I try shift the events from one calendar to the other, they do appear in the new calendar, but they do not disappear from the old. I have restarted Thunderbird, and also tried this on another computer with the same results. Both szstems are Windows 11, Th underbird 115.10.1 I would be very grateful for any suggestions

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

How can the Lightning mini-calendar (upper left) be made to show multiple months (like a whole quarter) Outlook can do this, has for many years. If there is a setting, I cannot find it. Is there an add-on?

Thanks,

Greg

Hi I run thunderbird 115.5.0 (64bits) on linux 22.0.4 up to date and try to connect to a remote calendar on ovh's nextcloud 27.1.4 up to date following this link I get calendar's address https://plusjamaisca.ovh/index.php/apps/calendar/p/D6rJcrHYJJj9xxx near by name's calendar and it show up on thunderbird. However I can't create any event. This is the message : an error occured while writing in the agenda I get the same problem with windows 10 While I have 2 androids mobile working perfect and another linux 22.0.4 working well also

My OS is Linux Mint 20.3 Una base: Ubuntu 20.04 focal Thunderbird version 102.4.2 (64-bit) "Today" marker does not advance to current calendar day after midnight of the previous calendar day in monthly view. The monthly view is the only view I use. If the < Today > link at the top of the calendar is mouse-clicked, it does not advance to the current day but remains on the previous day. To advance the day marker I have to click either "<" for previous month or ">" for the next month and then click Today. At that point the calendar will return to the current month and highlight the current day. This problem was also present on a previous version of LM (18.3) My add-ons are: Cardbook v. 83.6 ConfirmBeforeDelete v. 1.7.0 Lightening Calendar Tabs v. 2.8 Provider for CalDAV & CardDAV v. 4.3 TaskviewFlexLayout v. 62.9

There are two disabled extensions which could be uninstalled as they have been disable "since dirt was young,": TabAddressBook ToDo.txt Both were automatically disabled by Thunderbird due to incompatibility and I have no further need for them The active extensions are used with regularlity. This is a "livible" problem but but an irritation. Searches with multiple search engines have turned up nothing on this issue since 2020 and/or v. 68 of Tbird. Thank you in advance for any assistance you may provide on this issue. Mozilla software has bee my default software of choice, also "since dirt was young," and for what it's worth (which is very little) I check viable alternatives virtually every six months to see what your "competition" has to offer. Particularly, your configurational granularity is STELLAR! Once again, thanks!

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.

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

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?

When sending out an invite eg for Sat 9:00 The attendess receive it as being at eg., Sat 18:00 or 5:00 when vviewed in webmail. We use icewarp mailserver. When using icewarp mail client or webmail the issue is not present only reproducable with Thunderbird.

Events on external calendar created before 102 update all show, or did, I assume to due to Offline Support, but updates, changes, new events added since were not syncing, and after Unsubscribing and attempting to re-add the ext. calendar, Thunderbird is not able to 'find' the calendar at all, I just get a spinning ball.

The same external calendar is successfully being found and updated by another service. I use a Mac.

No matter how many times I re-create the link, I cannot get my subscription calendars to either work at all or if they do they work very rarely. Forcing a sync doesn't help. I can see the same calendars just find online and in other calendars including but not limited to Mac OS Calendar.
