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

Hello all,

I am posting this discussion because i am amazed at the fact that I cannot find an email client that is able to appropriately handle calendar invitations to/from myself for multiple email addresses and associated calendars.

With Outlook, my issue is that Outlook views my Exchange account as the default calendar account, so that when I accept an appointment to any other non-Exchange account (eg IMAP), the person who sent the invitation gets an 'accept' email from my exchange email address, and not from the email address to which he/she sent the invitation. This looks very unprofessional.

Thunderbird works better and allows for calendars to be matched to email addresses, but has a bug with accepting calendar invites that still has not been resolved: https://bugs.horde.org/ticket/13664

Is anyone aware of an email client for Windows that is able to appropriately handle multiple email accounts (exchange, imap, etc) and associated calendars (exchange, caldav, etc)?

Hi

I recently upgraded my Thunderbird client to v102. The calendar export options have changed and when reviewing the Release Notes Release Notes I note in the "Changed" - Support for importing and exporting calendars from Outlook CSV format was removed

This has significantly impacted my usage. This is where my timesheets are created / stored. This format is excellent for further analysis and billing. To use html or ics is very limiting and problematic for such purposes.

From what I have found online, all ics to csv convertible tools are a extremely poor substitute

Can this be reversed or can someone suggest an add-on to remedy this situation ?

Thanks

I can't see anymore if an email contains an .ics file. It showed a notification about asking what to do, but I clicked "More" -> "Not ask again" (or something like that) And now I can't find where I can show again this notification in the email header.

(As well if you know how I can download the .ics file like any other attachment would be really helpful, currently it doesn't show it)

I'm not seeing my task lists in the Google calendar list when I add a new calendar. I still have the Provider add-on installed but it seems to be bypassed by the internal TB add calendar functionality. That is I don't see an add Google Calendar option any more only Computer and Network. Using Network and my gmail email address I get shown my Google calendars but not my task lists. I would like TB to catch up with tasks but can wait. Or am I missing some thing?

BTW I tried Mailbird and it shows me all my Google calendars and task lists, but its expensive so not an option.

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.

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.

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!

I need to sync TB with Outlook.com calendar. But tbsync will not work with TB 102.0b8. Apparently hasn't been updated as yet. I can always back up to the previous version of TB, but I'm afraid I will lose features in this new version. Any help would be appreciated. BTW, this particular PC of mine is running Windows 8.1 due to the needs of a particular business application I use.

As mentioned in title I cannot use the calendar function at all. Same with tasks function:

• I can open the calendar tab, but that's it.
• There is no calendar on the calendar list, and the 'plus'-icon to add a new calendar is greyed out.
• There are buttons to change the views (week, day etc) but these also are greyed out.
• Same issue with tasks: I can open the tab, but cannot add any tasks

It all worked with older versions of TB. I had several calendars in place, no problem. But after some upgrade everything is gone. The calendars, originally set up on TB, are still there, but only accessible on the g-account...

Version: TB 91.11. Add-ons: Provider for google calendar

Any idea? I really want to use TB calendar function instead. If I could at least only set up a new calendar, that would be very helpful. Thx a lot in Advance!

When I enter an event on Thunderbird, it is immediately reflected on my online Google Calendar. However, when I enter the event on google calendar website, it does not automatically appear on my Thunderbird Google Calendar. Don't understand this. The only add-on I have on Thunderbird is the 'Provider for Google Calendar' (to allow bidirectional access to google calendar). I don't see any settings to fix this. Help! Note: It updates when I press 'synchronize' on Thunderbird, but I don't want to have to remember to do that. Should be automatic!!

Version 91 works correctly on other machines. On one machine that is updated to 102.0.1: Create a New Task DOES work for CalDav calendars. Convert mail to task DOES work for local Home calendar. Convert mail to task does NOT work for CalDav calendar. No task gets created. (It does still work in 91.) Move a task from Home to CalDav DOES work if the Home task was created with New Task. Move a task from Home to CalDav does NOT work if the Home task was converted from mail message. CalDav is DAViCal (on Linux, Apache) which is still serving TB ver. 91 machines. All TB 91 and 102 instances are running on Windows 10 21H2 with Firefox 102. Any advice? What more can I tell you?

I use Google calendar, which supports tasks and I get the message "Please select a calendar that supports tasks" in the today pane under the tasks window after I eliminated the Google calendar provider add-on. All the menu items for tasks are greyed out. Google calendar supports tasks. When will this be fixed?

I´m using TB 102.0.1 in Windows x64 Professional. I have config TB to work in English (menus, notifications, etc.), but with this update I have to change to Spanish language to allow the 24h format in Calendar. Every time I change to the Regional setting (Spanish) from an English language the Calendar change to AM/PM format, when I have config Windows to 24h format (HH:mm). I have always config TB to work with English menus, but I lost this possibility with the last update. Windows 7 Professional work with an Spanish language installation, and I suppose that in this new version of TB something has change with the Language/regional configurations. Is there any possibility to select the "time format" of the Calendar (24h to AM/PM or AM/PM to 24h)? Thanks

Hello,

After upgrading to Tb 102.0.2 calendar (Lightning) is not following "Date and Time Formatting" setting. Anyone knows how to fix it?

Thanks,

I have just moved from Outlook and I have converted my PST calendar to ICS. When I try to import the ICS file, nothing happens.

The JPG shows where the import stops.

Is there a solution and if so, how do I fix it?

I don't want to have to keep Outlook around just to use its calendar.

Thanks for any assistance.

Hi community,

I am looking for the way to change the start of the week to Monday. The default is Sunday start, but I can't find a way to change it so far.

My thunderbird version is 102.1.0 (64bit) for windows.

I will appreciate your help.

Thank you in advance, KT
