Is there a setting, like in Outlook, to snooze a reminder until "x minutes before start"?

If I have a reminder for e.g. 3pm, which is set to go off 1 hour before and then I want to snooze to give 5 minutes warning, in Outlook I would set it to remind me 5 minutes before. This works at any time up until 6 minutes before the event, regardless of when I snooze it..

But it seems that in TB, if you're away from your desk until e.g. 2.30pm, then you would have to calculate and manually enter "remind me in 25 minutes" to achieve the same effect.

I can't find an addon which does this, but happy to stand corrected!

Last week I started getting the attached pop-up

I don't use Calendar on Thunderbird (as it does not sync ) Not sure why this has started ..... I have tried putting in password and ticking the remember box - but it still keeps popping up.

Not sure how it happened but I've suddenly lost access to my Google calendar. On the bar on the left side of my calendar display screen there is a list of two calendars, Home and my email address, which I think is a Google calendar. Even though I check "Show all calendars" it does not show my email address calendar. And if I click on only to show my email address calendar it shows nothing at all. On my Pixel cell phone I can still see both the Home calendar and the Google calendar, so I guessing Thunderbird has just lost the link, although it shows a googleapi address when I click on properties. When I accept a Zoom calendar listing it has always and still shows up on the Home calendar. This seems most mysterious. Anyone have an idea of what I should do? Is there anyway I can rebuild the link to the Google calendar?

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

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.....
