Hello, I'm new to this Thunderbird I'm using a desktop computer with Win 10 and Office 2016. I have been having issues with outlook 2016, it keep asking for my credentials and I can't seem to be able to find any solutions so a friend recommended Thunderbird to me. I'm trying it and so far my emails are synchronized but not my calendar nor my address book. I cant seem to find where Thunderbird can sync with those two. I do not want to import into the app but sync like my iPhone is doing so if I enter an event in any of them it will show up in the other one. Pretty simple but I can not find this in the Thunderbird desktop app.

please help Kind regards Richard

I wish to merge TB115 calendar with Google calendar. Do I need Lightning? Do I need Provider for Google Calendar? Confused as Lightning features seem to be included in TB115.

I have three calendars and if I happen to forget to change which Calendar an event belongs on it will not let me edit that event to choose the correct Calendar. I can edit anything else on that event and I can choose a different calendar but it will not make the change when I Save it.

My Thunderbird profile is on a separate drive.

I had to reformat my computer. No problem with managing profile and all emails and folders, etc are ok. However, my calendar is blank!

Is the calendar not stored in your profile? Have I really lost all my dates and appointments?

Hey guys, the client I work for provided my with MS account to be used for communication. Since I am on Linux, these two things doesn't really bond well :) I was using mostly web access for MS Teams and Outlook OWA ...

However, I figured that I would love to try Thunderbird for at least emails (so I got them all my email at one place)...

After some discussion with client's ITHD (after they changed my license to E3 type) I managed to get the email working - so I can send and receive emails ... However, I cannot see the calendar so it's still almost useless for me for I don't see meeting request.

Any idea how to fix that? did any of you guys face the same?

Hallo ich verwende Thunderbird 128.0.1. Ich möchte einen Termin aus 2023 finden. Das beinhaltet der Filter aber nicht. Wie kann man Zurückliegende Termine finden? Danke im Voraus! Gruß Günter

Hi, Developers have already been notified since the 1st day of TB 128 version release about the problem. The so much appraised calendar in version 115 does not fully function in v. 128. The same old history is repeated. Sth is fixed, then sth breaks or malfunction. We, as users of Thunderbird do not have now the possibility to control all events registered in the calendar. To do that we use other applications then delete the calendar in TB and create a new one. Do we deserve this? Why the new foundation keeps asking us to contribute economically when we never have a fully functional application? (see attached image of Bugzilla records for the calendar issue)

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!

My Thunderbird calendar file is located on my organization's Nextcloud server. We just changed to a newer version of Nextcloud and moved everything to a new url, so my calendar updates no longer work. I need to edit the address of the calendar file. I open the Edit Calendar and can see the old url in the Location field. I can select and copy the contents of the Location field but I can't change it.

See edited screenshot

Thanks in advance for your help.

Hello Thunderbird Team, when I try to change an existing Date in the calendar, I have to delete and insert the Date again, now it's possible to make changes. What can I do to make changes directly ? Thank you Gunther

Hi, I am running TB 115.12.1 without any extensions. I have configured caldav accounts, on Forwardemail servers, on TB as well as on Android with DAV5x. Everything syncs without errors and most calendar entries are visible on TB, but not all!!! I have installed OneCalendar app along side TB and OneCalendar shows all calendar entries (as far as I can tell)!

Has anyone experienced similar issues? Any ideas how I can procede would be v welcome. What are the known issues with calendars on TB115.12.1?

Thx everyone.

Cheers, Adrian

Been using Thunderbird/Lightning for many years. In the latest update (115.10.1 (64 bit)), the EDIT button is not initially visible when I click on an event in my Calendar. In past releases, this edit button has always been visible in the pop-up window when I try to edit info in a New Event task. This happens SOME of the time, but not all. Any idea what changed, and is it possible to check out the code and change it back so when I double-click on an event, I see the edit button. At this time (not a big deal, but slows me down), when I go to edit an event, I have to move to a different monitor, resize the pop-up window so I can see the EDIT button, then finally click on it to edit the Event. In the past, the cursor immediately went to the EDIT button. Any info on changing this back the old way would be appreciated.

I started up my machine this morning, for Thunderbird 115.13 (I could've sworn that I had a later version last night, but updates and version numbers are Mozilla's problem, not mine) tells me that I can no longer use my profile with this fancy new version and need to create another one. After fuming about that idiocy for a while, I canceled the process and imported everything from my old profile.

It fouled up mightily on the passwords, but I got past that obstacle course.

Now, I see that my "Today Pane" is empty. Looking at the calendar, I see why: Thunderbird apparently pretended to import three calendars, but skipped all but two old events. I can create more empty calendars, but that is incredibly unhelpful. One calendar is local. One is an online ICS file published by an organization. And the third (the one that had two events picked up) is subscribed to an OwnCloud account's calendar, and may have worked. The first is obviously the most important, since I'd rather not spend time working out the database schema so that I can manually input every single event and appointment.

What hoops do I need to jump through to refill my calendar? I'm running on Pop!_OS 22.04 LTS, with the Thunderbird Flatpak (commit c2e09fc595198cf5c467ddad1fab56c0be512758584e16c3b933f2410968306a according to the command-line, if that gives any clues) installed. And again, I feel like that setup used a significantly later version of Thunderbird recently, so figuring out how to undo Flatpak's decision to downgrade would also presumably solve the problem.

Hi there, I'd like to be able to export events as a simple .ics-file. This has various reasons (e.g. sharing with others without getting updates) and I have seen this being requested by many others before. I know there is a work-around if you copy an event and then paste it into a text editor, but this seems like an awfully crude way to do something that should be super simple. I think that would be simple yet very valueable addition. Kind regards

Hi, I would like to add tasks to ‘my tasks’ however, I do not know how to connect a remote calendar that will be synced across all logged in devices. Please give me detailed instructions on how to add and select a calendar that supports tasks. I'll be gratefull for your help.
