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

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.

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)

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

In Thunderbird 91.7.0 on Ubuntu 20.04 calendar event snoozing does not work properly.

When a notification appears with more than one event in it, snoozing a single event causes the entire notification box to disappear with all events. The non-chosen events are not snoozed, which is good, so the notification reappears in a few minutes. But it's an annoyance and it used to work properly.

a lightning strike destroyed my motherboard, but I was able to salvage my harddrive. Now have a new laptop, have restored all my emails (from localfolders on salvaged drive) but am unable to get back my calendar. Any hints on how I can restore my calendar

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.

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)?

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 am probably trying to do something very stupid or it has a very obvious solution, but please bear with me. It seems my Thunderbird install, version 91.1.8 and now updated to 91.9.0, Win10, does not have a calendar function whatsoever. I tried to find the setup of calendar in every menu available. I have been running and updating this install for some time. For some reason , the outlook calendar satisfied me until now, but I am no more satisfied with the inefficient reminders. - it is not in the account setup - there is no calendar icon anywhere - it seems impossible to add the lightning extension to Thunderbird, as it is now supposedly included in TB: but where? Any hint?

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)

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

When I myself create a calendar event from scratch, I can edit it any time, via right mouse click/edit, or double click/click edit. I can edit this data anytime, both still while adding it the first time, or also after saving at any later time point.

In contrast, when I put an event in my calendar via mail invitation and clicking "accept", it shows up in my calenar, but I cannot modify it. On right click, "edit" is grayed out, and on double click, there is no edit field to click.

I'd like to e.g. set a category (like "travel" to be able to visually mark dates that need preparation, modify its name to be more specific, or add descripton text, e.g. the link for the video conference so that I have it available directly when it starts).

What I have tried so far:

• unaccept it, but still I cannot edit it via right or double click.
• copy and paste it as a new entry, but the problem persists

I use Thunderbird 91.9.0 now, but the problem exists for quite a while.

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.

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
