Thunderbird Support Forum

Hi there, I'm trying to fix my thunderbird client's calendar. I have a meeting invite from EEST(+3) at 3:00PM but when it gets converted to my timezone (+8) it shows up as 9:00PM instead of 8:00PM.

I am using thunderbird version 115.9.0 (64-bit). I also have my timezone set manually to Singapore.

Thunderbird 115.9.0 (64-bit).

I have my timezone set to manual, Europe.

I create an event for 30 March 2024 and the time is displaying in my time zone

I mark it as ALL DAY and it switches to Local Time (not a problem so far)

If I display the calendar as 1 month starting with 24 March, then the event shows properly on Saturday 30 March

If I scroll the calendar up to start on 31 March, now the event shows on 31 March.

If I edit the event, it says the timezone is Chicago.

Changing the timezone and resaving it doesn't help.

I just reinstalled Thunderbird v115 on new hardware with Windows 11. I share my wife's calendar, both hers and mine are Google. I used to be able to add events to both calendars. But now I can't seem to add an event to my wife's. When I click the save and close button the window goes away but I don't see the entry. The Read only box in properties is not checked. How do I fix this?

OS: Windows 11 Pro (23H2) Tb Version: 115.9.0 (64-Bit)

This is more a design question. With the Supernove release you moved the search bar and action icon into the top of the window. So on the email and calendar tab all the buttons are now on the very top next to search bar.

I configured to create new appointments in a new tab, not an extra window. But in this appointment tab the action buttons are in a seperate action bar below the tabs for email and calendar and not next to the search bar on top like I would have expected it according to the new design. I added screenshot to describe better what I mean. Is it planned to move the action buttons to the top for the new apointment tab?`

In general it is a bit annoying that the height of the toolbar on top varies. Like if there are buttons and you choose "show text below symbols" for it the toolbar is higher, of course. But then if you have a tab without symbols, e.g. the settings-tab or the new appointment tab, the height of the toolbar reduces. It would be great if this could be standardized.

Hi, When creating an event in the calendar view, I get my timezone displayed (Europe/Paris), I set my starting and ending time and save.

On event display in the calendar, I immediately notice that the time is off by 1h. On viewing the details, the right time is displayed but on 'Europe/Dublin' timezone. Changing it back doesn't fix the time, timezone always change after save.

I took a look at my settings, tried to use "use system timezone" (= Europe/Paris) of forced it to Europe/Paris, even checked the config editor, but nothing changed.

Did I miss a setting ?

My calendar is sync by CalDav (using TBSync), don't know if this could be related.

When I create a new calender entry on my mail server (mail.de), it is synced to the Thunderbird client.

When I create a new calender entry in the Thunderbird client, it does not sync to my server calender.

I use Thunderbird 115.9.0 (64-bit) on macOS 13.1 (22C65).

Thanks in advance for any support.

I have Windows 10 and Windows 11 installed on my computer. When I switch between them, I have the same email stuff, which is good, but I have different calendars, which is bad. How did I screw up?

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

I am trying Thunderbird with outlook.com email and calendar sync. Mail works fine, but I cannot connect using the tbsync and eas sync addons. When I try to add the account using exchange option, it just keeps querying for my credentials and reporting http 401 errors saying the credentials are incorrect.

What is the answer??

Last week (and for years before) I could view my Google calendar, edit appointments and respond to invitations. in Thunderbird, Now the Thunderbird calendar is completely empty (all 5 calendars that I have subscribed in my Google Suite account). The Google mail account still appears to work normally in Thunderbird, and the Google calendar is visible in other clients (e.g. Samsung Calendar under Android or Outlook (MS 365) under Windows 10). I am using Thunderbird 15.8.1 running under Ubuntu Studio 22.04 LTS. Any ideas what happened or how to restore calendar functionality? Was there a recent update to Thunderbird or to the Calendar module?

When I create a new calendar event, I would like them always to be Private, as a default. I would also like to suppress the requirement that the recipient respond.

Can either/both be accomplished with either an advanced configuration setting or with an add-on? I've searched add-ons, found none that accomplish either.

Thanks

Hello, For about 6 months, I experience repeated incidents on the synchronization of calendars between Thunderbird and an Android app. The Android app and the CalDav calendar visible on Roundcube are in line. But some, not all, events do not appear in Thunderbird. When I enter the same event in the same calendar in Thunderbird, it is visible and flows correctly to the hosting server and to my phone. I have several calendars and it seems to happen specifically with one calendar. Their setup look identical and they are hosted on different mail accounts but under the same hosting contract. In the error console, I see errors related to server sync :

  carddav.sync: Sync with server failed. CardDAVDirectory.jsm:652:11
      syncWithServer resource:///modules/CardDAVDirectory.jsm:652
  NS_ERROR_FAILURE: Incorrect response from server: 403 Forbidden CardDAVDirectory.jsm:245

The id and password look Ok. They are the same as the imap connection, that works Ok. Also, I raised the Sync frequency to 1 minute and the above error doesn't appear as frequently.

Does that sound familiar? Is there something I should me specifically check? Best regards, Emmanuel

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 copied and pasted a cell from a spreadsheet into a task and now I can't figure out how to get rid of it. There is a red box with the amount in it. I can delete the amount but the red box remains. This has been a problem for a long time and I was hoping someone had a solution. Thank you.

Running Thunderbird 115.8.0 (64 bit) on Windows 11.

Until recently all was working well accessing an outlook.com calendar (on server outlook.office365.com) using tb-sync and Provider for Exchange ActiveSync (latest versions).

Now I get the following error: "Could not authenticate, check username and password (HTTP Error 401)." (Meanwhile email is working fine with the same credentials).

I then tried using the new Thunderbird non-add-on exchange calendar integration, with identical results.

I then deleted all the cached outlook passwords (settings -> Privacy and Security -> Passwords -> Saved Passwords) and tried again, with identical results.

Interestingly, after deleting the passwords, closing and reopening Thunderbird, it successfully downloaded new emails from outlook.com (in spite of supposedly not having the passwords).

Help please.

Hi,

I am running Thunderbird 115.6.0 on Linux.

One of my calendars is on a Synology NAS with Synology Calendar.

I can create new events. As long as I don't close Thunderbird I can change the events as well.

But after a restart of Thunderbird I cannot change the events anymore. Ending up with a o/rjcpdo/pdo/faa15765-29e1-4470-80d7-5157b042bddf.1705244573723.ics [HTTP/2 405 Method Not Allowed 817ms].

I can still change the event for instance on the default calendar of Android. The changed events also show up in Thunderbird.

After changing the event on Android. I can change the event in Thunderbird again untill restart.

What I've seen so far is that the working link from Thunderbird is different than the link when it is not working. Not working. https://XXXX.synology.me:80/caldav/xxxxx/rjcpdo/pdo/faa15765-29e1-4470-80xx-5157b042bddf.1705244573723.ics

working: https://XXXX.synology.me:80/caldav/xxxxx/rjcpdo/faa15765-29e1-4470-80xx-5157b042bddf.1705244573723.ics

I've changed part of the link (xxxx) but it is the extra pdo part in the not working link.

Anybody any idea what is going wrong here?

Regards
