Exported ical file from Google Calendar and then went to import into Thunderbird. This previously worked in the same installation. The import failed and the error console displayed the attached message. Restarted Thunderbird. Calendar showed ready and is not read only. Same problem.

Week starts on Sunday. Events scheduled for Monday through Thursday. Select event set for Thursday and Crtl+P. Print preview shows event scheduled for Monday, not Thursday's event.

I updated to TB151.0 and lost access to my Outlook e-mail and calendar. After re-loading OWL my e-mail returned. However, I am unable to re-link on a read/write/synchronize basis to my Outlook calendar. I have tried adding a new calendar in every way I can think of and nothing works. I am tired of fighting with TB over this and am about to dump it and set up my accounts on Outlook. Please help me give TB one more chance.

I updated Thunderbird to version 151 yesterday and my Outlook e-mail and calendars did not port across to the new version. Re-installing the e-mail account was fairly simply using the account hub. However, trying to add my Outlook calendars to Thunderbird is proving to be much more difficult. Any advice or suggestions would be greatly appreciated.

I don't know what to do when February 29 is in my calendar, 2026 is not a leap year. I've found nothing to help me. I have the latest version if Thunderbird. Thanks

Hello,

I want to use TB to access my GMX CalDAV calendar. Basically, this works fine. But completed Todos disappear from the list after a day or so ("Show completed tasks" is checked). If I export the whole calendar to a ICS file, the todos are included though.

Is this a bug or is there a configuration where I can change that behaviour?

Thanks for any help, Markus

Hello,

i used the new feature to add my icloud calenders to thunderbird. that works fine. But the existing icloud Birthday calender was not separately choosable and dose not appear in thunderbird. what do do? Thank you!!

Best Simon

Is it possible to have my Outlook calender (the email is already in thunderbird) in my thunderbird and the calender should be editable and when I add events, I also want it to show on my calender in Outlook. TBSync is not working anymore. Please help me!

hi all. if i create a new blank Task it automatically pre-selects today's date as the start date, and if i create a Task from an email it sets the date the email was received as the start date. i know can filter tasks lists, and hide columns, but the real issue is how it looks on the calendar; with the fixed start date, setting a due date in a month's time results in a fixed, ongoing task for a month. is there any plugin or setting that will just stop TB setting a start date that i can't change, or letting me explicitly set it myself?

Apple ID and password are saved in Thunderbird but every time I open Thunderbird it now askd for apple ID & password. Was working OK originally about 3 months ago but itn the last 2-3 weeks has started to ask for this info, If I type it in with my apple ID and the apple specific password then the calendar opens. It I say save password the next time I open Thunderbird it asks for Apple ID and password. and so on and so on.....

I recently transferred to a new Win 11 system. I copied the profiles over and all my address book and settings are working. I have found that my calendars are not. I have three sub-calendars attached to my Home calendar, one was downloaded "USHolidays" and is working, the other two I created and are grayed out. The hover message says they are "momentarily not available." How do I fix this so they appear?

Using TB 147.0.2 on Windows 11. Installation went very smoothly, including importing all my IMAP, Gmail, and iCloud accounts. Kudos!

However, my iCloud account has four calendars (personal, shared, travel, work) and TB only sees two of the four. I can't pinpoint any reason why. There's nothing special about the two it sees or the two it doesn't, as far as I can tell.

Any hints? Suggestions? Ridicule?

I accidently unsubscribed my current calendar. It does not list anymore, I do not know how to list unsubscribed calendars. How to re-subscribe it? (Window 11 w/latest Thunderbird). thanks very much.

Help. Help. I have been a very happy Thunderbird user for many years. I have linked my microsoft exchange calendar to thunderbird with the TBSync and Provider for Exchange ActiveSync.

With the upgrade to version 148, those add-ons no longer work.

So I downgraded to 140 ESR and those two add-ons were ok.

But when I tried to link them to my calendar, they would not sync. I received 401 and 403 errors from the automated setups. And the manual setup, asked for my password over and over again. They all worked beautifully before.

Please how can I get them to work again. I do not want to have to shift to outlook.

thank-you
