Thunderbird Support Forum

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?

Hi. I just started to use thunderbirdb calendar and I'm a bit confused about 'Tags.' Should I be able to add a tag to a new event or task? If so I see no option to assign a tag to an event or task.

How do I distinguish between an event and task?

Thanks, James

I use Thunderbird calendar for all my events and without it I am lost. Yesterday, I wanted to export my calendar to be imported later by an online platform. I used the export function. I noticed however, that under the name of my calendar on the left pane this has appeared ( . export). I thought the ics file is already created, so I went ahead and deleted the strange ". export" item that appeared under my calendar name in the left pane. What happened next was that all my events disappeared from my normal calendar window. My question is how I can get back all my events? Or how I can restore the ". export" so my events come back.

Additional information: I did not have backup for my calendar. I cannot locate anywhere the ics file I thought it is "exported" I am using the latest version of Thunderbird as of March 2024.

Calendar print shows two items where only one exists. See attachments of both the original Google Calendar and the TB calendar prints. If only one of the calendars is selected, the print is correct

It has been about a week now since 115.8 tried to install on my Windows 10 but could not without my password. I have been on Auto update for years now and could not put in correct password. It was suggested I go back to 102 and start over with a new account. I did. I have 102 and can send and receive emails. Problem is 102 does not show all emails that show in my same account when I log into Ionos.com host of my email account. I created another problem going to Thunderbird 102, birthdays. I have no access to my Thunderbird calendar not only for this month but all months this year and forever. I made a copy of everything in my account prior to going back to 102 to get a new password. How to I get my 2014 calendar back. And first thing I do if and when I get it back is to use a pen and paper to write down birthdays and whatever I want to remember and save it on paper just in case this happens again? Thanks.

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.

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!

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

Thanks lot Phil

Dear Sir or Madam,

I have come a long way using linux but there is one thing I am missing dearly in Thunderbird Calendar: I want to see the next x days to move around my appointments if needed and to see my future days. On Wednesday I don't need to see the past two days but Monday and Tuesday of the next week, so I can use the time without switching to a month view or move my calendar around.

Is this hard to implement?

Thank you!

Best regards Dejan

Dear All,

I'm moving away from proprietary platforms and am setting up Thunderbird to manage my calendars. My calendars are hosted on a Synology and synced via caldav.

Sync seems OK, but interface-wise, I cannot find a way to have my events showing their location, directly from the calendar view (even daily).Clicking on the event, the location shows, but I really need to see them directly from the day or week view (I'm a teacher, so at a glance, I need to know in which class my next lesson is).

Is there a way to set this up, or a feature to be requested?

Many thanks!

Calendar page does not fit on display window. Display is set at 100% (recommended) This was not a problem on previous versions. Day columns are wider. Can not find a way to adjust.

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

After moving from Win 10 to Win 11, I exported my TB calendar events on the Win 10 PC, and imported them on the Win 11 PC. Now I can't edit or delete the imported events. The "edit" and "delete" tasks are greyed out.

All help's appreciated
