Multiple SMTP server settings lost on restart

Hi, I have 20 or so email accounts configured and until recently they all used a single SMTP server without any problems. Recently, all but 1 stopped working and it seems they now each need a separate SMTP server setting up - that got everything working again. However, whenever I restart Thunderbird/reboot, all but 1 of the smtp server server setting are lost (only the default 1 remaining). Am I missing some way to save the settings or something please? Thanks in advance!

Isisombululo esikhethiwe

Well, another week has passed and it still works, so will close this query despite not know knowing what caused it or how it was fixed. All's well that ends well.

updates to the prefs.js file (which contains those settings) are done on shutdown of Thunderbird.

OPen the windows taskmanager and look for a Thunderbird task. When you shut Thunderbird down, it disappears from the applications group, but can still be running in the tasklist. Once you are sure it has actually ended, open your profile folder.

Type %appdata%\Thunderbird into a windows run dialog (windows key+R) and press enter. Open the profiles folder and hopefully you only have one profile under that. in the profile look for prefs.js files. Especially ones with numbers in the names.

Please report what you find.

Hi Matt,,

I did as you kindly requested and found a prefs.js file last modified a few mins ago (plus 23 other prefs files called prefs-n where n = 1 to 23 last modified in 2021 or 2020). In the prefs.js file I saw references to several smtp servers, which I had anticipated following your explanation wouldn't be there. After the first time of entering 20+ smtp servers and losing them, I only re-entered them as needed as its a bit tedious, but the prefs.js file has all the original ones I entered. So I restarted Thunderbird and they were retained this time. Then I rebooted, with the same result. Strange that the behaviour seems to have changed after about 3 weeks of being in place.

However, other than the default smtp server, they weren't 'associated' to the 20 accounts in their settings. So I (re-)set a couple of the accounts to use the appropriate smtp server and sent/recvd test emails and they worked. Then I restarted Thunderbird and checked that the associations were unchanged and resent/received test emails and all was well.

So the issue seems to have disconcertingly resolved itself after about 3 weeks of being in place ?!? No idea why it suddenly needed separate smtp servers, no idea why they disappeared or reappeared as described, a least it now seems to work for some unknown reason though I've no idea why.

Many thanks Matt. Best regards, Conway

Hi Matt,

Today all the smtp servers have disappeared again from the settings, except for 2 - the default one and the one I used for testing before sharing my previous message. I'm fairly sure the machine hasn't been rebooted or Thunderbird restarted since then but unfortunately can't be absolutely certain (I usually put it in sleep unless it needs updating rather than shutting down).

I wonder if you may be able to help with any insights please?

Kind regards, Conway

Check if your prefs.js file has been set to read-only.

Also, check tools > developer > error console after startup and during operation for notes related to perfs or accounts.

The support documentation contains information about requirement for oAuth in Thunderbird post V98.8. I suggest you check your settings and ensure you are using oauth as the authentication method.

This is entirely irrelevant. I posted the text in the wrong tab in the browser. Sorry folks.

No worries Matt :-)

Thanks Wayne,

Prefs.js hasn't been set to read-only, it has full access.

I just rebooted yet again and the last settings I had are retained again this time, though I had only re-entered smtp details and selected them for 10 of the 20+ accounts.

The console you mentioned looks cool - it doesn't show anything that appears relevant but since the symptom hasn't appeared this time that isn't surprising.

I'll re-enter the rest of the smtp details and stop/start thunderbird and laptop a few times monitoring the console and report what happens.

Many thanks.

Slightly odd update. I re-entered a couple more smtp server details and it just so happened that thunderbird said it needed restarting to update something, so I did that. When it restarted, new smtp server details were there for everyone of my accounts (in addition to those I had entered/re-entered recently), even 2 that I had never bothered setting up smtp details for.

So it looks like some change happened in Aug that forced a requirement to have a separate smtp server for each account, but maybe the implementation wasn't quite perfect and the update thunderbird just installed fixed it. I've no idea really, just guessing. Does anyone have any insight into this?

It would be nice to know if I should expect them to disappear again, but I guess time will tell anyway :-).

A bug fix was undertaken to ensure all SMTP entries in the preferences were loaded into the dialog. What caused the issue is still under investigation. But users should no longer see it.
