Hello.

I read that thunderbird works with Microsoft 365 and modern authentication. I tested with Microsoft 365 accounts and it worked fine. The problems come with an accounting of Microsoft 365 operated by 21vianet service.

I configured according to https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 with the IMAP and SMTP settings from https://support.microsoft.com/en-us/office/settings-for-pop-and-imap-access-for-microsoft-365-operated-by-21vianet-ca51235d-afc5-4d7d-843c-3616a37d5771

It complaints "The IMAP server partner.outlook.cn does not support the selected authentication method. Please change the 'Authentication method' in the 'Account Settings | Server settings.'"

In SMTP settings there is no option to configure OAuth2

Company uses office 365, I have my Thunderbird. Since a couple of weeks sync issues appear (i.e.: TB has no right to delete folders in office 365). Finding a solution took several hours in various forums - nothing helps. - the only suggestion I didn'T try so far is asking the office365 helpdesk.

Problem description: When I delete folders they reappear at the old position. empting the trash yields also reappearance in trash. Same for moving folders - a copy is made, but at the old position and empty folder remains. They are gray - so hidden folders. Overwriting obviously does not work, as the folder already exist, but is not accessible. subscribing/unsubscribing does not work. In office365 the folders do not occur. If I create a folder in office 365 (web, outlook) it appears in TB. When I delete it in office 365 (web, outlook) it disappears in office 365 (web, outlook) but reamains - in gray - in TB. By now, the number of gray empty undeleteable folders has grown significantly. Only solution I got sofar is to switch from TB to outlook. :/

In the past I had used Thunderbird for both email and calendar for multiple accounts. I just downloaded Thunderbird onto my laptop (PC running Windows 11) and added all of my accounts and they are all synced. However, I can't edit or delete any event from any of those accounts directly in Thunderbird, although if I make changes on a different device they will sync and update properly. I never had this problem when I used Thunderbird before. I didn't see any permission settings that would allow me to do this so I'm stuck. Any suggestions? Thanks!

I've been using Thunderbird for years with no issues but suddenly this week it froze and although I could send e-mails from my Mac (running on Sonoma 14.5) I couldn't receive any. There was no message error, just nothing happened: it was frozen. So I finally opted to disinstall and then reinstall Thunderbird and now have incoming messages again but everything else I had: all my tags, e-mails older than a day ago, my address book have all gone. I've tried doing "import from profile "default" then choosing to import accounts and settings, address books, and mail messages but just get a message that "import failed unexpectedly, more information may be available in the Error Console" but I've no clue how to find the Error Console in question. Can anyone walk me through how to fix this issue and recuperate my old Thunderbird account without using all sorts of technical terms? I'm not IT-fluent! Many thanks.

Hi all,

Sorry for asking again, but after reading all the posts here the problem is still occurring.

When I launch Thunderbird, I'm asked for new data (Account Setup), like there is no profile available.

The application seems unable to locate or recognize my existing profile, but the profilefolder exists and its almost 90Gb of data. Should I complete Account Setup windows with my data?

Please help me! Tried with thunderbird -p command to repair or select another profile but with no success !

- installs.ini Default=Profiles/xxx.default Locked=1

- profiles.ini

Default=Profiles/xxx.default Locked=1 [Profile0] Name=default IsRelative=1 Path=Profiles/xxx.default Default=1 [General] StartWithLastProfile=1 Version=2


User Agent Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:115.0) Gecko/20100101 Thunderbird/115.11.1 OS Windows_NT 10.0 19045

For the last 2 or 3 days I have been receiving the above message when accessing emails. I have experienced this problem occasionally in the past and for a day at most, the problem usually associated with virginmedia. However this is now proving to be disruptive and I don't where the problem lies, with Thunderbird or Virgin. None of my settings etc. have been changed and I can access everything if I go directly to the virginmedia website but the handling of the emails is cumbersome. Any ideas?

I suffered a BSOD on my fully up to date Win10 Pro (v 22H2, build 19045.4474)

Upon rebooting, Thunderbird is failing to open. The error message is:

   Unable to open the folder Inbox on xxx@example.com because it is in use by some other operation. Please wait for that operation to finish and then select the folder again.

There is no other process using the Inbox folder. I have rebooted and the error message persists. It looks to me like the more correct message would be that the Inbox or the profile is corrupted.

I see other threads asking how to restore a corrupted profile, but none of the answers are very useful. They all see to be tips on how to restore a backup of the profile at %APPDATA%\Thunderbird\Profiles.

If I had a backup of that folder, I wouldn't need to ask how to recover a Profile after a crash.

If it helps at all, when I opened the Error Console in Thunderbird, I see the following messages:

``` Uncaught Error: Component returned failure code: 0x8055000a [nsIMsgFolder.updateFolder]

There must be some tool that validates the Profile independently of Thunderbird.
