sending email stopped first with messages reading,

Sending of the message failed. The message could not be sent using Outgoing server (SMTP) smtp.btinternet.com for an unknown reason. Please verify that your Outgoing server (SMTP) settings are correct and try again.

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.btinternet.com timed out. Try again.

BT then tried to help again through screen sharing, since when incoming email have stopped, message reading,

Sending of password for user Manod did not succeed. Mail server pop3.btinternet.com responded: Server error - Please try again later.

i was warned that changing from pop to imap could mean the loss of all my email, true?

please, I value my Thunderbird having spent years building up many folders and sub-folders for emails and would like to retain these even if i have to start with a new Thunderbird account. My Thunderbird is 38.5.0 I also use Firefox and Openoffice phone numbers are 0208 478 9681 and 07443 480 509 if that helps and of course i will call you back. thank steve

Let's begin by trying the settings suggested by BT:

The incoming POP or IMAP server, and the outgoing SMTP server is mail.btinternet.com The port for POP is 995, 993 for IMAP and 465 for SMTP. The connection security is SSL/TLS, the authentication is normal password, and the User name is your email address.

If your account is currently set up as a POP account, you will have to add it again as IMAP if you switch to that type of service:

http://kb.mozillazine.org/Convert_a_POP_account_to_a_IMAP_account

Before you make any major changes, it's a good idea to backup your profile:

Thank you for taking the time to reply. I will work through what you suggest and come back to you next week. best wishes steve

I attempted to make the changes suggested ie, "The port for POP is 995" However i received the following warning, "you are about to override how Thunderbird identifies this site" "Legitimate .. public sites will not ask you to do this" Certificate status "This site attempts to identify itself with invalid information" "No Information Available" "Unable to obtain identification status for this site"

I have not of course proceeded. Can you tell me why you suggest, The "port for POP is 995" and why i am receiving these warnings thank you

The secure connection port for POP accounts is 995, and that is what is recommended by BT (see link in my first reply). 'Certificate errors' are usually caused by having a security program, e.g. Avast, scan the secure connection, so you should disable that option if it's in place, as well as any 'email scanning' option.

https://support.mozilla.org/en-US/kb/error-codes-secure-websites

more options

Have followed your instructions in turning off 'secure connection' scan and 'email scanning' option for both sending and receiving

However for receiving i get the following; "Sending of password for user Manod did not succeed. Mail server pop3.btinternet.com responded: Server error - Please try again later."

and for sending i get: "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.btinternet.com timed out. Try again."

what else can be tried?

thanks again steve

Can't explain the sending error, unless your settings are different from the ones given above.

Did you try the recommended mail.btinternet.com for the incoming POP server, instead of pop3.btinternet.com?

more options

No i had only tried mail.btinternet.com for sending. Incoming was still pop3.btinternet.com. I will alter incoming to mail.btinternet.com and see what results. I have the settings you suggested for sending so it would seem that the fault is one beyond repair. Will try further with incoming and get back to you thanks again.

Quicker result than expected. Tried mail.btinternet.com for incoming and got following response, "Sending of username did not succeed. Mail server mail.btinternet.com responded: [SYS/TEMP] Server error - Please try again later."

Ok let's accept that for reasons unknown the present Thunderbird no longer functions. I really appreciate all your time and help so perhaps best not to spend more time on the problem and move on.

The new situation is perhaps how to retain the present Thunderbird folders and emails but download a new version and start using that. I want though to be able to go back to the old to recover past information and then copy-paste as necessary into emails on the new Thunderbird. Does that sound feasible and if so, where should I put the old Thunderbird and how? thanks again

re :"Sending of password for user Manod did not succeed. Mail server pop3.btinternet.com responded: Server error - Please try again later."

Check all your settings including the Username for incoming and outgoing because that error message implies your username is wrong.

I'm using bt pop and these are the settings.

  • incoming server name: mail.btinternet.com
  • Port: 995
  • Connection security: SSL/TLS
  • Authentication Method: Normal Password
  • User name: full email address
  • outgoing server name: mail.btinternet.com
  • Port: 465
  • Connection security: SSL/TLS
  • Authentication Method: Normal Password
  • User name: full email address


Set everything up as above click on OK Restart Thunderbird.

Hello Toad-Hall thanks for taking time to reply. Followed all you suggested and received the following, "Sending of username did not succeed. Mail server mail.btinternet.com responded: [SYS/TEMP] Server error - Please try again later"

What however i have noticed is that if I go to, options - security - saved passwords i read the following,

site user name smtp://smtp.brinternet.com (smtp://smtp.brinternet.com) Manod

this means that in this security area the changes made have not been registered. ie smtp has been changed to mail.btinternet.com for incoming and outgoing while Manod has been changed to manod@btinternet.com do I need to make changes at, options - security - saved passwords and if so how?

at, options - security - saved passwords it also reads. last changed 20 July 2019

that was before problems became serious and I did not knowingly make any changes at that date. Being unwitting I do not know of course what changes I may have made then.

Finally, why, though I have only ever typed my email address in lower case, ie manod@btinternet.com I keep seeing it (ie at account settings – account name) shown as starting with a capital M? Does this matter?

Not sure if all the above gets us any further but pleased to hear your reply thanks again steve

In passwords you can right click on each relevant line and select 'Edit Username' and then retype the username as full email address using all lowercase.

I recall in the past I had a same error and the following did fix it on that occasion. So it is worth a try. The BT and Yahoo servers were not in synch.

Use this link: https://login.yahoo.com/

reset the password to the same password you are currently using to access webmail and which is being used in your email client.

If for some reason, you are redirected to anything other than what that link says above, then clear your browser cache and re try.

re :site smtp://smtp.brinternet.com (smtp://smtp.brinternet.com) user name Manod

I assume that was copy pasted...I've just noticed that there is a typo error it should say 'btinternet' not 'brinternet'

Please double check your Account Settings for server name of smtp outgoing server.

went to options - security - saved passwords which i asume is where you were refering to when you wrote 'passwords' the only options were to copy username or password, but not to 'edit'.

unfortunately; smtp://smtp.brinternet.com (smtp://smtp.brinternet.com) was a typo not copy from original which is correctly reads bt..etc

The trouble is i have spent weeks trying to put this problem right and it is causing real difficulties for my work. Previously i suggested leaving the problem and moving on. I repaste what I wrote then and wonder if we might pursue the new rather than trying to solve what may just be unsolvable.

I would advise you try the following.... create a new profile. Use the 'Profile Manager'. http://kb.mozillazine.org/Profile_manager#Accessing_the_Profile_Manager

Then scroll down to see info on Creating a new profile.

Create a new existing mail account for the pop account.

You will then need to get all your emails from the old account into the new account. There are a couple of ways of doing this. Copy paste all mbox files (have no extension) from old profile pop mail account into the new profile pop mail account. You would need to exit Thunderbird first. If you are not confident in copy pasting the mbox files from old profile into new profile you can use the addon extension called 'ImportExportTools' to import the mbox files from the old account into the new account. https://addons.thunderbird.net/en-US/thunderbird/addon/importexporttools/

Image below showing example of mbox files.

I am going to work through what you recommend. Will let you know how I get on. much thanks as ever.

Afraid my technical knowledge is not up to following your instructions. I am sorry but I do not know how to find this 'profile manager'.

Actually i do not need to transfer all the old emails to a new profile/account/address. I just need them to remain accessible. A 'backup' perhaps to which I can go for an email when needed but not necessarily part of any Thunderbird. Does that make the task easier? Perhaps we should start with making a backup where all existing files and emails are stored. Then Thunderbird can be deleted in total fr5om this computer and we start with a new download? A new empty Thunderbird with the right setting would that be easier? I can resend the BT details if necessary.

Thanks for your patience and sorry my computer knowledge is limited.

It is highly likely that the problem is not with the program itself, so uninstalling/reinstalling Thunderbird will probably not resolve the issue.

You can right click on highlighted emails and use 'save as' to save each email independently as .eml files in a folder you created on your desktop, and when you click on them Thunderbird will open the email.

You can create a backup of the entire profile (mail accounts, address books etc etc). Exit Thunderbird first and access:

  • C:\Users\<Windows user name>\AppData\Roaming\Thunderbird

Copy the 'Thunderbird' folder to a suitable place for storage eg: external hard drive.

It is possible and more likely that the problem is in the 'profile name' folder, hence why I suggest you create a new profile. It is like starting from scratch.


re:I am sorry but I do not know how to find this 'profile manager'.

I have made a shortcut icon on my desktop which will auto open 'Profile Manager'. This has proved to be very useful.

Locate where the 'thunderbird.exe' is stored. If your computer is a Windows OS and 64bit:

  • OS (C:) > Program Files (x86) > Mozilla Thunderbird

If your computer is Windows OS and 32bit:

  • OS (C:) > Program Files > Mozilla Thunderbird

click on 'Mozilla Thunderbird' folder to see contents. scroll to find 'thunderbird.exe' file Right click on 'thunderbird.exe' and select 'Create Shortcut' It will say you cannot put a shortcut in that location and suggests desktop - click on 'Yes'. On desktop, right click on the new shortcut and select 'Rename' Call it: TB Profile Manager

Right click on 'TB Profile Manager' shortcut and select 'Properties' On the 'Shortcut' tab you will find 'Target:' If using 64 bit...It will say:

  • "C:\Program Files (x86)\Mozilla Thunderbird\thunderbird.exe"

If using 32 bit...It will say:

  • "C:\Program Files\Mozilla Thunderbird\thunderbird.exe"


Left click in that text area and use the right arrow key to go the far right until you cannot go any further. click on 'space' bar to create a space then type -P

So the line now looks like this - if 64bit:

  • "C:\Program Files (x86)\Mozilla Thunderbird\thunderbird.exe" -P

Or this, if 32bit:

  • "C:\Program Files\Mozilla Thunderbird\thunderbird.exe" -P

See image below as guide Click on 'Apply' Click on 'OK'

Now you have created a quick easy access to the 'Profile Manager'.

If Thunderbird is running, then exit Thunderbird now.

Double click on 'TB Profile Manager' shortcut to open Profile Manager

creating a backup of the entire profile (mail accounts, address books etc etc) sounds ideal, thank you. i will copy the 'Thunderbird' folder onto both the present computer C drive and a backup on a USB which i assume should be safe enough. However I do not understand how to access:

   C:\Users\<Windows user name>\AppData\Roaming\Thunderbird 

can you explain how this is done? I tried copy pasting the address, obviously with my user name inserted, into search facility on the start menu and the 'run' box on the start menu, but neither were able to identify the path. The report was that the path did not exist. Where do I type this address to locate the Thunderbird folder?

Wish I knew someone adequate to understanding your messages, but afraid I don't, sorry. Thank you as always steve
