Thunderbird Support Forum

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

TB Synch - Periodic Synch set to 1 minute Win 10 Home Imap Mail Server outlook.office365.com checks for msgs every 3 minutes TB 91.9.0 (64-bit) Provider for Exchange ActiveSync

I now have two issues, one is that on my IMAP accounts with my own domain, both the recent sent and recent received emails in a thread are showing up twice. This doesn't happen with previous emails in that thread or with gmail, exchange, outlook.com, live.com, icloud, etc.... Now, I have an issue where the pop ups for calendar notifications keep popping up non stop and either won't go away by hitting "Submit to changes anyway" or if they do go away, they immediately pop back up again. 115 is a big disapointment for me, it's been highly glitchy, many add ons no longer, some that should work, don't work properly, it was hyped a major upgrade and I see very little that distinguishes if from 102 in any meaningful way except some of the icons are more colorful. Is there a way to go back to 102? Either that or I may start using Mac Mail again due to all these bugs.

I have a Google Calendar, in which I manage My Tasks. I can't see my existing tasks in Thunderbird, and I can't add new tasks to the Google Calendar. New Task in Thunderbird is greyed out and the field next to it has the writing: "Please select a calendar that supports tasks".

I have seen that many had the same issue and understood that it is linked to how My Tasks in Google Calendar itself works. Is there really no workaround whatsoever?

If not, how can I manage tasks and share them with someone else (who uses Google Calendar or Apple Calendar, but does not use Thunderbird)?

Thanks in advance for your replies!

Hello,

In the Agenda view, I once made the "Find events" pane (shown in the answer to this question) disappear by reducing its size down to zero. Now I can't bring it back on. I love my big full-screen calendar, but this pane was still nice to have sometimes! I guess a toggle to display this pane should be accessible in the menu (e.g. View -> Agenda -> Agenda panes -> Find events).

Thanks for the good work. I love the new 102 version!

I just today (6/27/2023) downloaded and Installed Thunderbird on my Mac (latest OS installed).

I was able to successfully configure my Google account email and my company's Outlook/Exchange email just fine and I'm getting messages on both.

However, I do not see ANY calendar events whatsoever...not Apple (local) or Outlook.

I seem to be able to create an event on the calendar that's showing, but I'm getting nothing from Apple or Outlook.

I'm not so worried about local or Apple events, but I DO want to see my company's events that are on the Outlook Catalog.

Any ideas?

Thanks in advance!

Today I received from Ubuntu's repo the update to Thunderbird 102.2.2.

I have linked Thunderbird with my Nextcloud instance https://docs.nextcloud.com/server/19/user_manual/pim/sync_thunderbird.html

this is done by using 2 addons: - https://addons.thunderbird.net/en/thunderbird/addon/tbsync/ - https://addons.thunderbird.net/en/thunderbird/addon/dav-4-tbsync/

unfortunately they are both incompatible with Thunderbird 102 therefore automatically disabled.

How can I use Thunberbird 102 with Nexcloud?

I added the United States Holiday Calendar to my Thunderbird Calendar.

As it has zilliions more holidays than I care to see (World Pneumonia Day, for example) I would like to remove it. I added it as an internet supplied calendar, not stored on my computer.

Can someone please tell me how to remove it entirely? Also, is there a different, more modest calendar I might add somewhere out there?

Thanks in advance for the assistance. I have searched for a way to do this but have not found anything.

hi, I'm using the same TB Calendar setup for a while (3 years), in February 2024, calendar sync became erratic with showing under TB Calendar a warning : your agenda is temporarily unavailable, some events did not sync . but for the last couple of days, I'm unable to sync any events from my yahoo calendar towards TB calendar. the tbsync shows OK, reports no errors in log. could you help please , this is quite urgent matter for me. Thanks lot Phil

Thunderbird 102.6.1, Windows 11

Over the last several updates to Tbird (can't say exactly when it started), my Google calendar seldom gets updated, and then seemly only at random times. The "synchronize calendars" command has no effect. A week or more can go by with no update, although my computer is always on and connected to the internet. Exiting and restarting Tbrird does not help. Eventually th calendar updates itself, unpredictably.

When I add an event to the Google calendar in Tbird, it shows up immediately in other instances of the Google calendar, such as on my phone. So we know that Tbird calendar is talking to Google, if only in one direction.

I didn't see this problem mentioned in any of the help articles. If others have reported this problem in the Community, I didn't find the thread. Any suggestions?

After Upgrading to SuperNova (115.3.1) My caledar view just explode... I need like two 25"" monitors to get one week view as one. The columns just turn HUGE and cannot find a way to set them back to a viewable size. is there a way to fix this? Please your help and advice.

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!

I have been using Thunderbird and Lightning on Windows and Linux computers for several years. I just installed Thunderbird 102.6.1 on a new Windows 10 computer. I've spent at least an hour trying to find and install Lightning. I cannot find it. Web searches say to look in add-ons, Tools, the hamburger menu and Events and Task ... not of those exist in my Thunderbird.

How do I find Lightning?

For no reason I can discern, my Thunderbird Calendar reminders have stopped appearing.

I checked in the Options section and everything seems in order (see attached).

I am on the latest version of 102.5.0 Windows.

I've rebooted my laptop.

Any thoughts and suggestions welcome.

I updated to the new Thunderbird 115. I imported my folders etc with no issue with only 1 little problem - my local folders are in between my 2 email accounts and I can't seem to move it down but not a big deal.

The real problem is my calendar events. I had a very full calendar and after the update, my calendar is empty and blank. I have no idea what to do. Everything else imported fine. The calendar is the only calendar I use. Hope someone can help.

Thank you Norma

Have used the calendar feature for years. After update to 102.4.0 (from openSuse) the calendar pane is not visible. The "Calendar" entry in the View menu is greyed out. Don't see anything like this in search of the forum. The calendar tab is present, and I can see events. Is the pane gone, leaving the tab? Thanks.

Network calendars no longer seem to be working after upgrade to Thunderbird 102.4.1.

For example, my previously working calendar to this Google vCal calendar no longer syncs. I also had working read/write network CalDAV calendars that are now broken.

I tried deleting and recreating the calendars, but to no avail. Any help would be appreciated.

Here is some output captured from the Thunderbird error console:

When I install Thunderbird 102.1.2. (64) on my Windows 10 PC and install a calender (via net) with a link to my Synology DS220j NAS. Thunderbird shows a turning wheel for hours. In the task manager the "inbox" seems not to run. From then on, I get always the turning wheel when I start TB. I could stopp this by deleting the directory "calender-data" in preferencies and delete the Synology-Calender in TB afterwards. I see this behavior on 2 PCs. The Synology Caldav works fine with Outlook and some Androids. Has/had anyone the same issue and a solution how to manage it?

Hello this morning Thunderbird Updated in Germany to Vers. 102. At vers. 102. Calender shows no categories in Google Calender or Web.de Calender.
