Thunderbird Support Forum

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 ?

Thunderbird 115.1.0. R/W to a Google calendar using Provider.

I cannot dismiss calendar reminders. The Error console message for the failure gives:

rea[calGoogleCalendar] Modifying item [xxxxx] failed:2147500037: {

"error": {
 "errors": [
  {
   "domain": "calendar",
   "reason": "forbiddenForNonOrganizer",
   "message": "Shared properties can only be changed by the organizer of the event."
  }
 ],
 "code": 403,
 "message": "Shared properties can only be changed by the organizer of the event."
}

}

I saw an archived question outlining this exact problem (well, the exact error, not sure if it was with Provider/Google), but there didn't seem to be any resolution provided. I believe that I am not the event organizer for many, if not most, if not all, of the events for which I'm trying to dismiss the reminders, but I'm simply trying to dismiss a reminder. Some of the events are recurring, others are singles - it doesn't seem to make a difference.

Grateful for any help; I'm sitting at about 70 reminders I cannot dismiss.

i tried to import a csv file from outlook.com to thunderbird, and all the values are in the wrong fields. E-mail addresses and names of every contact are in the wrong fields. For instance, if I have 100 contacts, I have to edit them individually in Thunderbird after importing the file. This is not helpful. Is there a way to convert the file so I don't have to do this? Please advise.

When I enter an event on Thunderbird, it is immediately reflected on my online Google Calendar. However, when I enter the event on google calendar website, it does not automatically appear on my Thunderbird Google Calendar. Don't understand this. The only add-on I have on Thunderbird is the 'Provider for Google Calendar' (to allow bidirectional access to google calendar). I don't see any settings to fix this. Help! Note: It updates when I press 'synchronize' on Thunderbird, but I don't want to have to remember to do that. Should be automatic!!

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?

I'm not sure when this started happening but Thunderbird (115.3.1, Linux) is no longer sending email invites to my invitees, even if some of those invitees are on my same host. as "Organizer" I do get an email notice to my personal email, which is the default attendee, with subject "Accepted: testing", and body, "mfoley@novatec-inc.com has accepted your event invitation.", but nothing is sent to the other invitees on the list. I checked the error console which showed these messages after I created the event:

NotFoundError: No such JSWindowActor 'DevToolsFrame' 6

1701371572264 Toolkit.Telemetry WARN TelemetryStorage::_scanArchive - have seen this id before: 9c1e2d46-28f9-430d-86d7-398dd0ad3bdc, overwrite: false

Not sure these apply to creating a calendar event. My server settings are fine, I can send and receive mail to the Thunderbird inbox without problem. I can send email from the Thunderbird client without problem.

Any idea why I can't send event notifications to invitees?

Hi, I was trying to set up Thunderbird, but I noticed that the calendar was showing incorrect date+time. I did find a very similar issue very similar issue, but that seems to be because of flatpak (which probably isn't the issue here because I am on MacOS).

Current Time (real, also shown in Mac Menu Bar in screenshot): 03:52 of September 23rd. Time shown by Thunderbird: 22:30 (of the previous day apparently - Sept 22nd).

(Also note how the time shown on the calendar has two days combined. Ideally, 22nd Sept and 23d Sept shouldn't be together in the "Day" view).

Additional note: For fun, I created a new event for 23rd Sept at what seems like 01:30. After creating the event, the time seems to be set to 07:00 (which should be right, assuming that the "Waking Up" event is supposed to be at 09:00). Note that if I open the "Waking Up" event, the time is correctly shown.

ThunderBird Information: 115.2.3 (64-bit)

System Information: MacOS Sonoma - Version 14.0 (23A339)

System Timezone is set to be the same as the one in ThunderBird (Automatic Timezone setting in ThunderBird was even more wrong, by more than a day).

Please forgive me if I missed something too obvious.

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.

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

Hi, I use new version 115.1.0. When creating calendar event and adding attendees, they don't get the invite and I don't see the message that sent in sent items folder. Please assist

Hello,

Just started using Thunderbird for its calendar, but I can't find the settings for Calendar Events. I am aware that I can select a specific calendar and go to its Properties Window, but I want to access the app's settings for all calendars. Research shows that there should be a Calendar tab in the app's settings tab, but it isn't there for me. I only have the General, Composition, Privacy & Security, and Chat tabs. Can someone please help me get this tab to appear?

Thanks!

Since TB 115, I have issues with the "invite" functionality of Lightning, as follows.

It generates errors as follows:

• "invite" does not work. I can add emails to be invited to an event, but the invite is then not sent at least with the option "notify" + "send individual mail" (other alternatives such as open visible list of destinatories are not feasible due to privacy)

• when opening an "event" from the calendar, it displays in a full-screen format (see screenshot_2) that lists all invited attendees

• The "invite attendees" window works but has a strange pink block on top right (see screenshot_3)

• the page where the format of sending ("notify", "send individual mails") is not accessible any more

Currently the calendar as such works fine. But the "invite" function is critical for the use I am giving as transnational NGO to invite to meetings etc. All worked fine with previous TB versions.

System config: WIN10 prof, all updates installed, fully licensed, AMD Ryzen 9 5900X etc. (mid-end system built in 2022).

Thanks for looking into a solution.

Problem: I'm 76 years old and technically self-taught. I have 2 Windows 11 computers. One desktop and one laptop. Both are fully updated and utilizing Office software, specifically Outlook. Not too long ago I happily discovered Thunderbird and like it soooo much better. QUESTION: Within Outlook, my calendar is displayed as iCloud Calendar which is ok for me. The one thing that is keeping me from exclusively using Thunderbird is not being able to import my iCoud calendar into Thunderbird. Is that even possible and if so, how? Please keep your response as simplistic as possible. Thank you for your time and consideration given to my inquiry.

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

Thunderbird 102.12.0 (64-bit) Arch Linux

Using fastmail as my email provider and their caldav server. I can create and generally edit calendar events. Changing the calendar itself in the event appears to save but the color of the calendar and the edit doesn't reflect the change. This is the same manually using (or not) the synchronize button. There is no read only setting on for this caldav calendar.

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 have exported the calendar entries to an ics file. When I try to import them on another PC it fails with an error indicating something about the entries having dismissed an alert and needing to be read only. How do I get around this?
