Do you have a security program scanning outgoing mail?

Yes, I have AVG free on both computers.......

Disable the email scanning component if it's on and see if there is any difference.

I have scan outgoing emails on the pc that is NOT slow in Sending. I disabled scan outgoing emails on the other pc where it is slow in sending and it made no difference to the Send sit-and-wait phase.

I also disabled Email scan completely on the problem Thunderbird and it made no difference in the speed of the Send function.

The first diagnostic step to take now is to run TB in safe mode (hold Shift when you launch TB) and see if there's an add-on that became incompatible with the update to TB 52.

I am sorry; it did not make any difference. The only add-ons I have are Lightning which came as default and Theme Font and Size Change which I added myself. My 'good' TB has bot both of these add-ons as well.

Does this happen with the same account and the same server settings as on the PC that doesn't have the problem? Is there anything in this list that is different between the slow PC and the normal one?

The PC that does not have the TB problem has four IMAP accounts on, whereas the PC which has the TB slow problme has got two IMAP accounts on them, but they are not the same ones as on the good PC. I am now desperately trying to find version 45.8.0 of TB to try it, but cant find it anywhere. It is as though Mozilla does not want us to use older versions.

Whilst still wishing to solve my existing problem, on a side note, where can I find an older and downloadable version of TB please?

You can get TB 45 here.

What are your SMTP settings for the slow accounts? It may be that the problem is due to incorrect or obsolete settings, not the version of TB.

I don't see any SMTP settings on either of these programmes. It says Server Name: imap-mail.outlook.com on both. Port: 993 on both Connection Security: SSL/TLS on both The emails were configured automatically by TB and these settings are on both versions of TB.

I went to the site you recommended to get TB 45 but there is no downloadable version... It is just an index. I had seen this site before and unless I am doing something wrong, where and how do I download older version of TB from that index list? Thank you.

For your information, the slow TB takes about ten seconds for the Send message to leave the screen, whereas the fast TB is instantaneous. This is quite annoying to sit and look at the screen for the message to disappear...

For your information, it takes about 10 seconds for the Send message to disappear from the screen on the slow TB, whereas on the fast one it just happens instantaneously. It is quite annoying to sit and be compelled to watch the message on the screen until it disappears.

Your problem is not related to the version of TB. See this post for updated server settings for Hotmail/live/outlook.com.

With respect, my problem is not that I am unable to connect to the servers and/or send/receive emails.... I have already explained my problem. Furthermore, I do not have Office 365. I am using Office 2010 on both PC'S... And, moreover, I am having this problem only with one Thunderbird on my work PC with version 52.1

I have connected with Outlook Office 2010 these same IMAP email accounts and both Outgoing and SMPT servers are all the same OUTLOOK.com servers and no mention of Office365.

My outgoing SMPT server is on Thunderbird: smtp-mail.outlook.com Port 587 I am sorry, I do not feel changing the server names as stated in your above link to xxxx-office365 is going to solve my issue. I could try to change it, but I am afraid I will mess up the whole thing. . My rationale being: if one TB is working fast enough with the existing servers why should the other TB be slow when it comes to Send an email.

May be I should rephrase my problem. It is not that I cannot send or receive. I can on both Thunderbirds. BUT, on the latest version that I have 52.1.1 this is what happens: After writing a new email, i click the Send button and it takes at least 10 seconds for the email message to disappear from the screen. Whereas, with the previous version of TB on my other PC the Send function is instantaneous.

You can do whatever you like with the advice provided. I do not have Office 365 or Outlook or Office. My Hotmail account works in TB 52 with no delays after changing to the suggested settings. If you read the cited links, you will notice that you can also use imap.outlook.com and smtp.outlook.com. This problem has existed for about a month and countless users have adopted the necessary changes with success.

I have a third PC on which I have TB version 45.8.0 which has also been behaving slower than the other PC which has the same version 45.8.0 - but performing much faster - i.e. two of the same versions of TB on two different PC's. I did, however, change the server settings on this second one to the ones you suggested, i.e. outlook.office365.com smtp.office365.com And it made no difference. After clicking Send, my message stayed on the screen for a good 8 - 10 seconds until it disappeared as a Sent message. I am.. just about to give up..... Are we running out of ideas/solutions with this?

Did you delete any old passwords after you changed the servers, i.e. from Tools/Options/Security/Passwords/Saved Passwords, OK, restart TB, enter the correct passwords when prompted? Using the proper settings eliminates all delays with Hotmail/outlook.com accounts, on any version of TB, so if you still have problems, it is due to factors outside of TB. I have already cited a list of factors that affect performance; it includes the solution for Hotmail.

Yes, I did that on several occasions both on my TB versions 45 and 52 and I am having the same delays. I have now reverted to the old server names i.e. imap-mail.outlook.com and smtp-mail.outlook.com

Something else is happening now.... One of my email accounts is not sending the email and I am getting this error: An error occured whilst sending mail. The Mail Server responded 5.3.4.554.5.2.0 STOREDRV.Submission. Exception:SendAsDenied Exception. Mapi ExceptionAsDenied; Failed to process message du to permanent exception with message cannot Submit message.16.55847:69000000, 17.43559" And a Zillion 00000's after that....

I am gradually giving up on this...... Now, I can't even send email and I am too scared to change the settings on my PC's..... I wish I had not started this in the first place.
