I've been using Thunderbird for work for a few years and a few months ago my calendar integration with my Google Calendar stopped working. I've tried everything I can think of including re-installing calendars, but without success. My Thunderbird at home can still accept invites, but not on my work computer despite verifying that the calendar address and such is the same.

Initially, when I'd click 'Accept' on an invite, nothing would happen (ie no prompt, failure etc), the invite would just stay there without response. Now it's asking me if I want to link it with one of two different calendars I have, both of which I've verified under the calendar on Thunderbird that it isn't associated with an email address (has the yellow bar at the top saying if you want to use this calendar to store invitations you need to associate with an email address).

I can't think of what to do for next steps for troubleshooting, any thoughts?

It seems that this guide does not work anymore: https://support.mozilla.org/en-US/kb/adding-a-holiday-calendar

The point 5 ("From the Format list, select iCalendar (ICS).") is not there anymore. The wizard shows directly a form where you can enter the "Location", but if you enter the URL of an ICS file, it says "Could not find calendars at this location. Please check your settings."

Is there a different way to add these calendars? (and any other ics calendar you can find on the web)

Thanks

Hello, Thunderbird just auto-upgraded to 102.3.1. And now, one of my three Google Calendars are 'missing': Holidays in US and Medical are OK, but ToDo isn't showing. I tried to unsubscribe ToDo and re-subscribe and it was back... until I changed to November and it was gone again. Changed back to October and it's gone from all months again. I read a few articles from months ago and thought perhaps the issue had been fixed for release, apparently NOT. Good thing I can still see all of my calendars on my phone... Just tried unsubscribe from all three calendars and added Medical and ToDo back - OK... until I change months again and ToDo disappears from all months. Just unsubscribed from all Google calendars (including the email address calendar) and subscribed to ONLY ToDo... back until changed months again. Don't really want to set up my whole gmail account again, but if that's what it take to get all my calendar back I'm willing to do it... I'd hate to lose Thunderbird as my email client, but this is a real 'deal breaker'. Perhaps it's the name "ToDo" that's the problem??? I guess I'll try changing that to see if it's the problem...

Hi,

I want to sync with read-write access to my Google Agenda on Thunderbird. I already have a Google mail account set up, works fine. I followed the steps on the blog post by downloading and installing the Provider add-on.

When I go to add a Google Agenda, I enter my email account and a popup opens and closes immediately (the popup asking me to log into my account I imagine).

See the screenshot attached as I managed to take a picture right as the popup appears and disappears immediately.

Please Someone help ?

I have followed all the suggestions I can find, but my Thunderbird Calendar will not sync with the Outlook Calendar on Windows 11. I am using TB Sync, but every time I try to add my Outlook Calendar ? It refuses to accept my Password, even though it is correct, and the User name and email are too ! It shows as error code 401, and cannot authenticate ?

I have tried a suggestion to create an 'App Password' to use in my Microsoft account, but the options described do not exist in my account !

Can anyone please help ?

I am running Thunderbird on Linux, using version 91.4.1 (64-bit). My OS is set to use a 12 hour clock, yet all times in Thunderbird use a 24 hour clock. I checked out the help article, and it seemed to indicate having the locale set to English (United States) in preferences should get me the 12 hour clock, but both Application locale and Regional settings locale show that option. Switching does not change anything. I tried looking in the config editor, but I was unable to locate any of the settings to change time formats mentioned in the help article.

Why is Thunderbird stuck on a 24 hour clock?

The help article I tried: https://support.mozilla.org/en-US/kb/customize-date-time-formats-thunderbird

This morning there was an update to Thunderbird. When I reopen the program I can no longer see the right end of the screen. There is no toolbar to scroll over to see that side, and I've been unable to resolve this in the settings. I am using Density > Compact and I do not have any add-ons installed. See screen capture. I will have to stop using TB if this can't be resolved.

Hello,

I am getting old, my vision is much weaker than it used to be and now I have what is commonly referred to as "Eye Floaters." There's nothing that can be done to fix that, but with dark themes I can usually not see them. Due to a bug (or feature, if you prefer) in the Windows 10 Scaling and Layout settings, once you change them, there's no going back, at least that I have found. Low vision forced me to try to increase the font size in Windows, and in the (seemingly irreversible) process, I set Scaling to 150%. That fixed the problem of text being too small, but it also affected many programs in a negative way. Everything is waaay too big. For example, the menu bar and overall page header in Firefox was massive, taking up nearly a third of the top of my monitor screen. It did the same thing in Chrome only worse. The page footer was almost as big and between the two it left about two inches in the middle to view a website's content. This was very annoying to say the least.

I found a fix for Firefox, by changing the ui.textScaleFactor to 100. However, that did not work for Thunderbird. I found a way to fix it, by going back to Thunderbird 102, and now the email and address book are fine, and the calendar works fine, except for the colors with really bother me. I can't read the screen without looking away to the right of the screen. This is because the colors are too bright, and that is in a dark theme. I don't even want to look at a light theme. It would probably blind me.

Here's what I have. The 1st image is what it looks like, and the 2nd is what I would like to make it look like. Is it possible to do that? Please excuse the low quality color replacement on the 2nd image...

Information on how to add the Google 'Tasks' into Thunderbird Calendar: I have a gmail imap account using OAuth2 as Authentication Method.

File > New > Calendar, select 'Google Calendar' >  click on 'Next' choose or enter: gmail email address   > click on 'Find Calendars' Select 'My Tasks' and click on 'Subscribe'

You may be asked to enter password as per Oauth2 Authentication.

See image. It shows the selection available when you follow instructions. It shows where 'My Tasks' is located in the Calendar list. I selected 'My Tasks' and then clicked on 'Task'. Create the Task and save. Task is shown in Thunderbird and on the right side you can see the Task is displayed via the webmail access using a browser.

Hi, I have set-up 2 calendars for my 2 email addresses on Thunderbird email client with Provider for Google Calendar, and besides the invites, the calendars work well with 2 way sync, etc.

Problem is when I accept an email invite on Thunderbird from either account it automatically goes to one calendar and not the other and I can't find a way to get it to the proper calendar.

- One calendar is from MS Exchange/Outlook (synced with Thunderbird) where all invites go - One calendar is my Google/GMail calendar (synced with Thunderbird) where invitations do not go Interestingly on my Google Web version (Google Calendar site, not Thunderbird) the invites are properly allotted to the right calendars. So I am guessing it’s my Thunderbird setup.

Have attached 4 screenshots: - Calendars listed - Settings for the MS Exchange calendar - Settings for the Google calendar - Screen where I accept the invite. The invite is sent to the Gmail address and the response is the proper Gmail address. Also something odd about me "not being on the list" shows up whenever I accept from any account.

Any help is greatly appreciated!

When adding a future date event from the Lightning calendar Today Pane (with mini-calendar displayed), I click on the date when I want to add the event, then click the New Event link below the calendar. This brings up the New Event dialog, but the dates in the Start and End fields default to today's date, not to the future date I selected in the Today Pane, so I have to re-select the desired date in those fields. In older Lightning versions, those preselected dates used to default to the date I selected in the Today Pane, which is obviously when I want to add the event. Is there any way I can get this old behavior back in the current version (102.2.2)? If not, I'd like to request that this behavior be added, or at least have the option to be added, in a future release. Thank you for listening.

It's not on settings. I found this css code but don't know how one installs css for thunderbird. I got as far as opening the config editor on the calendar options. But I don't see what entry it is.

Alternatively if I can change the weekend colors that would work well. They are nearly the same yellow as the CURRENT color.

Hello everyone,

First of all I would like to say that I love Thunderbird! I am also not very IT literate when it comes to manipulating software or using the correct language so please bear with me, I find these a bit overwhelming.

I was hoping someone could help me with with my calendar, I have tried to change settings on other software and it went terribly wrong and I don't want a repeat. I have read the various help files but it doesn't make much sense to me :(

I have a domain with Dynadot for my website and email, it's basic but does the job for my small business. It has IMAP abilities and an autoreply but that's about it- there's no calendar app but does have an email app... just. On my Windows laptop I use Thunderbird for all emails and calendar requirements which is great when I'm using my laptop. However, I do meet with participants and don't always use my laptop so I need a way to be able to view and book appointments using my andriod phone.

I also have a member of staff who needs access to my calendar and be able to book appointments for me and vice versa. As we are both out and about a lot the calendars need to be "live" and easy to reach, much like the paid for Outlook shared calendar.

At the moment my member of staff doesn't use Thunderbird as their main software, they have Outlook. We did try another email/calendar app but their shared calendars were just links that we had to save and keep logging into, it was a nightmare and without the updating we had some double-bookings. I don't want to go through that again, it was embarassing.

I would greatly appreiciate your wisdom in how I can resolve my issue and easy step by step guidance on how to do it properly. I am the type of person who will get locked out of everything!

Best wishes Rebecca

Hi,

For some reason, I don't see the calendar subscriptions in the Calendar view. I restarted the app, and I'm at the latest version. I did install an add-on that made things a bit wonky (a markdown plugin, but I'm not sure if that's when the calendar subscriptions disappeared). I uninstalled it. I noticed the problem after I had uninstalled the add-on.

Does this problem seem familiar to anyone? If so, how did you fix it?

Thanks,

L

I'm migrating to a new computer and from Windows 10 to W11. I have successfully exported/imported the contacts using the export tool, but cannot figure out how to ex/im the calendar. I am using a SanDisk drive to move the files. Both systems have TBird 102.1.2 (64-bit).

Please give step-by-step instructions to do the calendar (only) ex/im. I do not use the Mail feature.

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
