I copied and pasted a cell from a spreadsheet into a task and now I can't figure out how to get rid of it. There is a red box with the amount in it. I can delete the amount but the red box remains. This has been a problem for a long time and I was hoping someone had a solution. Thank you.

Running Thunderbird 115.8.0 (64 bit) on Windows 11.

Until recently all was working well accessing an outlook.com calendar (on server outlook.office365.com) using tb-sync and Provider for Exchange ActiveSync (latest versions).

Now I get the following error: "Could not authenticate, check username and password (HTTP Error 401)." (Meanwhile email is working fine with the same credentials).

I then tried using the new Thunderbird non-add-on exchange calendar integration, with identical results.

I then deleted all the cached outlook passwords (settings -> Privacy and Security -> Passwords -> Saved Passwords) and tried again, with identical results.

Interestingly, after deleting the passwords, closing and reopening Thunderbird, it successfully downloaded new emails from outlook.com (in spite of supposedly not having the passwords).

Help please.

Hi,

I am running Thunderbird 115.6.0 on Linux.

One of my calendars is on a Synology NAS with Synology Calendar.

I can create new events. As long as I don't close Thunderbird I can change the events as well.

But after a restart of Thunderbird I cannot change the events anymore. Ending up with a o/rjcpdo/pdo/faa15765-29e1-4470-80d7-5157b042bddf.1705244573723.ics [HTTP/2 405 Method Not Allowed 817ms].

I can still change the event for instance on the default calendar of Android. The changed events also show up in Thunderbird.

After changing the event on Android. I can change the event in Thunderbird again untill restart.

What I've seen so far is that the working link from Thunderbird is different than the link when it is not working. Not working. https://XXXX.synology.me:80/caldav/xxxxx/rjcpdo/pdo/faa15765-29e1-4470-80xx-5157b042bddf.1705244573723.ics

working: https://XXXX.synology.me:80/caldav/xxxxx/rjcpdo/faa15765-29e1-4470-80xx-5157b042bddf.1705244573723.ics

I've changed part of the link (xxxx) but it is the extra pdo part in the not working link.

Anybody any idea what is going wrong here?

Regards

Thanks lot Phil

Dear Sir or Madam,

I have come a long way using linux but there is one thing I am missing dearly in Thunderbird Calendar: I want to see the next x days to move around my appointments if needed and to see my future days. On Wednesday I don't need to see the past two days but Monday and Tuesday of the next week, so I can use the time without switching to a month view or move my calendar around.

Is this hard to implement?

Thank you!

Best regards Dejan

Dear All,

I'm moving away from proprietary platforms and am setting up Thunderbird to manage my calendars. My calendars are hosted on a Synology and synced via caldav.

Sync seems OK, but interface-wise, I cannot find a way to have my events showing their location, directly from the calendar view (even daily).Clicking on the event, the location shows, but I really need to see them directly from the day or week view (I'm a teacher, so at a glance, I need to know in which class my next lesson is).

Is there a way to set this up, or a feature to be requested?

Many thanks!

Calendar page does not fit on display window. Display is set at 100% (recommended) This was not a problem on previous versions. Day columns are wider. Can not find a way to adjust.

Hi

I recently upgraded my Thunderbird client to v102. The calendar export options have changed and when reviewing the Release Notes Release Notes I note in the "Changed" - Support for importing and exporting calendars from Outlook CSV format was removed

This has significantly impacted my usage. This is where my timesheets are created / stored. This format is excellent for further analysis and billing. To use html or ics is very limiting and problematic for such purposes.

From what I have found online, all ics to csv convertible tools are a extremely poor substitute

Can this be reversed or can someone suggest an add-on to remedy this situation ?

Thanks

After moving from Win 10 to Win 11, I exported my TB calendar events on the Win 10 PC, and imported them on the Win 11 PC. Now I can't edit or delete the imported events. The "edit" and "delete" tasks are greyed out.

All help's appreciated

Hello,

I run a. Thunderbird v 78.14.0 (64-bit) on a Macbook Pro 13"mid 2012 with Mac OS 10.10.5 (Yosemite) b. Thunderbird v 115.5.1 (64-bit) on a Macbook Pro 15" mid 2012 with macOS 10.15.7 (Catalina)

How do I make happen, that I sync the calendars in both Thunderbirds constantly, i.o.w. instantly (like for example the iMAP emails do)??

I find the option for new calendars: "On the network" ... Which network is here meant??? In the help there is not much info about it. I am not using and will not use Google or any kind of "social media" (!)

Can I use my own homepage host (which has some webspace left) in order to sync? Or for example an online storage like mega.nz ?

Or could the both macs just sync the thunderbird calendars just via WiFi/WLAN directly (AirDrop ?) or via Bluetooth ??

It would be so great if calendar sync would be as easy as the emails do!

Thanks for you advice!

Best wishes, Thomas

I have been trying to sent event invitations from my time zone (Central/Chicago) to Washington DC (Eastern/New York) for a meeting which will physically take place in DC for all participants. As an example, if I set the time to 2:00 PM Eastern Time it corrects to 1:00 PM for all invitees. Unfortunately, the invite does NOT indicate the time zone.

How can I avoid this problem? Should I just leave the invite time setting as my my time zone and it will automatically show the correct time in the receiver's time zone? (e.g., for a 2 PM physical meeting in DC, should I send it as a 1 PM meeting Central Time)?

Also, will this work for those opening the invite in GMail or Outlook?

Thank you!.

This question hints that there might be a way to subscribe directly to the Google holiday calendar rather than downloading and importing it. Does anyone know how to do this?

Thanks!

Hi Team,

I recently started using THunderbird as an inbox and calendar tool a new business we have started with my team. I have a couple of questions.

1. I have the e-mail app on my android phone, but how can I get thunderbird calendar on it? 2. My other two businesses use google domain and e-mail accounts and my personal calendar is also on google. How can I sync the thunderbird calendar with my google calendar, so that events which I create, receive, accept on one of the calendars (i.e. Thunderbird) will automatically appear on the other (i.e. Google). 3. And is there a way to sync the calendars so that I can edit calendar events from everywhere (regardless of where they have been created)?

Thank you in advance.

Kind Regards, Alex

I recently subscribed to the TB calendar for USA holidays. I reported a problem with the calendar itself and got no response to my last reply ([https://support.mozilla.org/en-US/que.../1438331|here]).

There is also a problem with the way TB displays holidays when more than one appears on the same date for the same region (i.e., where UID:<xx> is the same), possibly also depending on the CATEGORIES or CLASS codes, though I didn't check for that.

For example, for Feb. 11, 2024, TB shows "International Day of Women and Girls in Science" (UID:un), "Super Bowl" (UID:us), and "World Day of the Sick" (UID:world). It does not show "Lunar New Year," which appears in the calendar with UID:us. It appears that when there is more than one holiday on a given date for a given region (US in this case), it displays only one.

This is also the case for May 27, 2024, which is not only "Decoration Day" (UID:us), but is also "Jefferson Davis' Birthday" (UID:us), but TB shows only Decoration Day. (And the calendar has no entry for "Memorial Day," which is the federal holiday on that date. That was the original problem I asked about.)

The entries are listed below for the calendar I downloaded from TB.

After adding my nextcloud calendar via CalDAV in Thunderbird 115 (no plugin) I can perfecly add or remove events to the calendar and they get synced well, however, if I receive a notification the button to dismiss them does not do a thing. Firat I thought this is related to Birthday reminders, but it is also true for events I have added to the standard calendar via Thunderbird.

Sorry if this is a double post, but I only found similar issues with older versions of Thunderbird and a plugin for the calendar.

Hello from New York City!

Is it possible to share a calendar event. When right clicking an event brings up a pop-up menu but a command to share the event does not exist.

Similar calendar event sharing functionality exists in other web based calendar software.

From an avid user on Win11x64 with Thunderbird 115.7.0 (64-bit).

Any clues appreciated. Thank you.

I have added my own categories in the Thunderbird Calendar New Event window, but I am unable to edit or delete either default or added categories in the list. How do I edit this list? NOTE: this is different than mail categories.

I just subscribed to the US Holidays calendar on the TB Holidays page: https://www.thunderbird.net/en-US/calendar/holidays/ -> https://www.thunderbird.net/media/caldata/autogen/United-States-Holidays.ics

I noticed that Memorial Day is missing for all the years included in the calendar. I just ran across it, so I haven't looked thoroughly.

Is there a way to report this to someone or to correct it and submit a corrected version?

Thanks!
