Thunderbird 102.5.1 (64-bit) Windows 11

Since a few years back my Lightning calendar lost all the color backgrounds for categories, which was a plugin that does not work anymore. The small sliver of a color bar on the right side of the event on the calendar page is not helpful to see in a glance what category is coming up in a few days. I have several job categories such as Photography, Video Recording and Audio Job. If I can color code AND SEE them at a glance when I am in the month view is a great help. I am not sure what purpose it serves to have a thin slice of color on the right side of the event! If the whole background of the event line has that color it will serve some purpose. I researched and tried all the css hacks and config edits but nothing seems to work. Is there any help that we can get? I see that others are also looking for a solution that works in the latest version. Any help would be greatly appreciated. Thanks.

Hello

My TB data spans decades, for emails, tasks & events [oh, & also contacts]. I've lost count of however many TB iterations / versions it's lived thru. It began life yonks ago in Win7, & lives now, for many years, in Linux.

For at least a couple of years, my Calendar has had this annoying problem. For many Events, but not all, it is just impossible to directly duplicate them. Both Ctrl-C Ctrl-V, & RMB-Copy RMB-Paste, simply do NOTHING [for it seems like the majority (but not entirety) of my Events].

Research lead me to https://bugzilla.redhat.com/show_bug.cgi?id=2015334 [my distro is #Arch not #Fedora, but IMO that's irrelevant]. I was galled to see that bug report was closed without action or solution; also that it was raised only with Redhat not actually Thunderbird.

In exasperation, recently i conceived this inefficient albeit effective workaround: for the target Event, RMB-ConvertTo-Task, then edit said new task to desired date for the intended duplicate, then convert said task to a new Event... then correct all the text formatting that was lost by this silly indirect process.

I've wondered if possibly the database has become corrupted somehow due to surviving all the historical TB version changes, to cause this duplication problem. So last night i thought i'd Export the Tasks & Events ICS file, then Import it into a clean TB profile elsewhere [in some vague hope that this process might magically "fix" any putative data corruption]. The Export nominally succeeded, being an 81 MB file. The Import failed every time, with the error msg per pic.

What is a frustrated TB user now supposed to do, please? [btw, current version is 102.10.1 (64-bit), in ArchLinux KDE Plasma].

Hello, i need to synchronize the TB calendar with my macbookpro calendar app. it seems that what we find on internet is not appropriate to the current versions. thanks for your assistance regards

Hi, I'd like my new events to be set to privacy "show time and date only" as long as I don't change anything. How / where can I set the default?

Is there a way to change that for all my existing events as well?

Thanks!

I am looking for a way where my entries and invites from my work email and calendar, to be viewable when I am out of the office, on my iPhone. I know there is a way to link calendar entries from Gmail and iCal to be viewable on Thunderbird. But trying to find a way where my Thunderbird entries, can be viewed away from my desktop.

If this even possible?

Hallo, When I import an ics file I get the error message "File contains no data". However, an import in the Windows calendar shows entries. Whats going wrong here? The file to be imported was exported from the Android phone from the Business Calendar. It was not possible to attache the File.

Last month, my caldav accounts all stopped syncing. I get a n error stating (NS_ERROR_UNKNOWN_HOST). I am using TBsync, and have multiple calendars set up for sharing on our webhost, and all worked perfectly for about the last year. I have tried up-dating Thunderbird, reverting to an older copy of Thunderbird, running Thunderbird in troubleshooting mode, un-loading and re-loading the extensions, performing a system restore on my PC to a date before the trouble started, basically everything I could think of. Below is a portion of the error message I find in the developer tools error reporting:

[calCachedCalendar] replay action failed: <unknown>, uri=https://mail

Can you help troubleshoot this issue? We use Thunderbird on our department for crew scheduling, and are suffering without this feature being operational. Thank you, JMB

Hello!

Is there any plans in future releases to add native Exchange Web Services functionality for syncing of calendars?

Currently the only way to sync your calendar and meetings if you use EWS is to use tbsync and excange provider both by the same author (john bieling bless your heart)

https://addons.thunderbird.net/en-us/thunderbird/addon/tbsync/ https://addons.thunderbird.net/en-us/thunderbird/addon/eas-4-tbsync/?src=dp-dl-othersby

These are 3rd party extensions and therefore if there's a major new version of thunderbird... they're broken for a period of time.

I am a linux user, so my only other option is Evolution Mail, which is not bad, but it's nowhere near as good as thunderbird.

it does however have an EWS plugin that is natively developed along with it. I know Jason Evangelho works for you now... I know we've got a linux guy in there... (love you man)

Hope you do it! it'd basically make it the best email client in the linux community, just sayin'

I am using Thunderbird Lightening Calendar on MacBook Air. First it worked fine but now when I click on INVITE ATTENDEES the usual box to add invitees is hidden or not displayed. see attached image

In our company the Thunderbird calendar meeting invitations are off by an hour.

Refer to screenshots where it shows the current time in Windows is 7pm but the time in Thunderbird is 8pm.

Condition found: Thunderbird time is 8pm. In the screenshot with the calendar view you can see in the bottom right hand corner Windows indicates it's 7pm but the red time indicator in the Thunderbird calendar view is 8pm.

Desired condition: Thunderbird time should match Windows time of 7pm.

Please note that: Mexico observed summertime daylight saving time starting in 1996. In late 2022, the nation's clocks "fell back" for the last time, in restoration of permanent standard time. [https://en.wikipedia.org/wiki/Dayligh.../Daylight_saving_time]

Things tried: Installed the latest Thunderbird on fresh Windows machine. Googled: [Search]

Does anyone see what I might be doing wrong?

My event edit windows do not have any timezone settings (see picture below). I have tried a new profile and looked through all the settings, but do not see a reason for them to be absent. ... help :-)

Its just not there as an option. All the tutorials I see say to select caldav... Its just not there. I enter the caldav URL in case it now "Autoselects" (No tutorial I can find says it does) and it can't find any calendars, so I am assuming something is wrong/missing/messed up somewhere.

When I receive emails with calendar invitations, I can't put the event into my calendar because Thunderbird says that I have "no writable calendar". In the Properties for my Calendar, when I try to associate the Calendar with an email account, I see two, sometimes in the past three, identical email addresses listed, and that's the email address that I need to associate with the Calendar. Sometimes, I just keep trying one after the other until my Calendar becomes writable and I can save the emailed invitation. However, most of the time, no matter what email address (in the Properties list) that I choose, I still get the error that my Calendar is not writable.

I use Thunderbird with Exquilla for Microsoft Exchange. That works fine. Earlier, I had tried Thunderbird with Owl for Microsoft Exchange, which also seemed to work but my office suggested continuing with Exquilla.

Thank you for any assistance with this showstopper problem. Best regards, Damon

My TB is up to date (102.7.2) and in the last week or so my Yahoo calendar is not syncing and when I hover over the warning symbol it says '...temporarily unavailable'. My Outlook calendar is syncing and showing. Any ideas how I can fix it ?

Thanks - Ed

Some event reminder popups aren't being displayed. There's no apparent reason as to which reminder popups will work properly, although the problem seems to occur mostly with event reminders dated in the future or with reminders that use a custom reminder date/time (e.g. 16 days prior to the event). If I can't depend on the reminder popups then the calendar feature is useless to me.

Also, another slight annoyance is that the events cannot be sort by date, it refuses to sort them in chronological order. FYI...sort by name works.

Hi Team,

Can someone tell me a way for me to link my calendar from my home computer to my laptop via Thunderbird?

Reference: I use my home computer more but when I am traveling I would like to see my calender schedule mirror my home computer.

Kind regards,

Shamus
