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

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

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

Hello,

I run a. Thunderbird v 78.14.0 (64-bit) on a Macbook Pro 13"mid 2012 with Mac OS 10.10.5 (Yosemite) b. Thunderbird v 115.5.1 (64-bit) on a Macbook Pro 15" mid 2012 with macOS 10.15.7 (Catalina)

How do I make happen, that I sync the calendars in both Thunderbirds constantly, i.o.w. instantly (like for example the iMAP emails do)??

I find the option for new calendars: "On the network" ... Which network is here meant??? In the help there is not much info about it. I am not using and will not use Google or any kind of "social media" (!)

Can I use my own homepage host (which has some webspace left) in order to sync? Or for example an online storage like mega.nz ?

Or could the both macs just sync the thunderbird calendars just via WiFi/WLAN directly (AirDrop ?) or via Bluetooth ??

It would be so great if calendar sync would be as easy as the emails do!

Thanks for you advice!

Best wishes, Thomas

I have been trying to sent event invitations from my time zone (Central/Chicago) to Washington DC (Eastern/New York) for a meeting which will physically take place in DC for all participants. As an example, if I set the time to 2:00 PM Eastern Time it corrects to 1:00 PM for all invitees. Unfortunately, the invite does NOT indicate the time zone.

How can I avoid this problem? Should I just leave the invite time setting as my my time zone and it will automatically show the correct time in the receiver's time zone? (e.g., for a 2 PM physical meeting in DC, should I send it as a 1 PM meeting Central Time)?

Also, will this work for those opening the invite in GMail or Outlook?

Thank you!.

This question hints that there might be a way to subscribe directly to the Google holiday calendar rather than downloading and importing it. Does anyone know how to do this?

Thanks!
