I have Thunderbird version 115.5.1 installed on my Windows 11 laptop. I have logged into my gmail account and subscribed to google calendar. I have turned the off default reminders for events and don't have any extensions installed, but when I create a new event and select "No Reminder," Thunderbird automatically sets a 30-minute reminder. I can modify the reminder by editing the event after saving, but I can't directly create a new event with no reminder.

My work schedule revolves around the first Thursday of the month. Creating events recurring on the first Thursday or Friday is not a problem of course.

However, I am trying to set up recurring events /relative/ to the first Thursday, e.g. for the Monday of that week.

Can this be done in Thunderbird Calendar? Happy to do some manual editing of calendar files if that would help.

Thank you!

Been using Thunderbird/Lightning for many years. In the latest update (115.10.1 (64 bit)), the EDIT button is not initially visible when I click on an event in my Calendar. In past releases, this edit button has always been visible in the pop-up window when I try to edit info in a New Event task. This happens SOME of the time, but not all. Any idea what changed, and is it possible to check out the code and change it back so when I double-click on an event, I see the edit button. At this time (not a big deal, but slows me down), when I go to edit an event, I have to move to a different monitor, resize the pop-up window so I can see the EDIT button, then finally click on it to edit the Event. In the past, the cursor immediately went to the EDIT button. Any info on changing this back the old way would be appreciated.

How can I get back to being able to search for an old calendar event of up to 2 years ago, now that a recent Thunderbird update removed that ability and replaced it with the 7 search periods option box to the left of the 'contain' search window?

In Outlook you can forward an appointment that is not created by yourself to someone else. In Thunderbird this option seems not available, or is it? Adding attendees to an event that you did not create yourself does not work.

I have set up my google calendars in Thunderbird so I can have a shared work calendar.

The calendar has the "prefer client-side email scheduling" option enabled, and the correct email (my work email) is selected, yet invites are still being sent out from my gmail account.

I'm using thunderbird 115.10.1 on Ubuntu Linux. I've set up a second calendar and associated it with an email account hosted by Polaris Mail. That email address has worked fine within thunderbird for everything else for a long time, but I only recently associated it with a calendar. When I get a meeting invite, for example from a gmail user, and accept that invite, selecting "send a response now", no message ever arrives at the email of the inviter and no email ends up in any of my folders (drafts or sent). It is like nothing happens. The event *is* accepted and added to the calendar, but no respose is created or sent. I have another email account and calendar and meeting acceptances and responses seem to work fine.

I've looked at all the settings I can find and they seem appropriate and analogous to those with the working email/calendar. The correct email address appears in the calendar properties opened by right-clicking on the Calendar and selecting properties.

Any help? Thanks.

I'm setting up TB for the first time with multiple email and calendar accounts. Some are gmail / google, and others o365.

The primary TB account's calendar doesn't seem to be syncing fully. It's an o365. account. But the email is working.

I added an event on my Outlook for Android on my phone. Its appearing in OWA, and in New Outlook on my computer (so it did sync from mobile Android device to server, and from server to my New Outlook on the Windows desktop). But its not appearing in TB.

Not sure what to check or what the issue might be.

Also, I'd love to replace Outlook Android on my mobile with what I think is K-9. But can't get the same account referenced here to connect to the outbound server.

Welcome any help, and appreciate you all doing this collaborative work.

Hi Everyone!

I am currently on Thunderbird 115.10.1 (64-bit) and for a few days now, I can't open the calendar tab. The "Today Pane" is working and showing events though.

When going to "View" the items "Calendar" and "Tasks" are greyed out though.

Any idea on how to get the calendar back? The company will move us all to Exchange and Outlook soon, so I thought I might "survive", but it is pretty impractical have to open my calendars separately in the browser. You only notice how often you use something, when you don't have it. ;-)

I have a calendar event with multiple people set up. I want to add a person to the event and only send a new invite to the new person (and not send a second invite to the original invitees). Is this possible? thanks.

Profiles was bad enough, as Thunderbird can never open the zip file (the wording of the alternative method is gobbledegook, and there are no recognisable files if you attempt to decipher it). At least you can set all your email addresses up manually - you can't physically re-types five years of calendar entries. The infuriating this is that when you start the import, the calendar entries appear before your eyes for up to five seconds and then the program crashes ... again and again and again. I must have been trying this on and off for years now and still nobody has fixed it.

According to thunderbird, this event starts at 10:30 (second image) and runs until 11am (end time is correct.

Google calendar correctly has this event as starting at 10:00 (first image) running until 11am. This event is synced with google calendar and my outlook calendar (outlook has it as 10:00 as well).

It's not a time zone issue because the start time is off by 30 minutes and the end time is right. Any idea what's going on?

(Clearly a calendar sync that gets the times wrong isn't so useful.)

I cannot dismiss calendar invites sent to me from others on the Ubuntu platform. I can dismiss invites that I have initiated. FYI this doesn't seem to be the case on the windows release - I can dismiss "foreign" invites.

The only way to dismiss these invites is to delete them from my calendar (which I prefer not to do). Thanks.

After importing events from the old ics calendar into the existing CalDav calendar. TB sent invitations out to all attendees, even for past meetings. How to avoid this?
