How to configure Thunderbird with an Exchange account - urgent =(

Hello team, does someone happen to know how to configure Thunderbird with a corporate Exchange account? The mail servers were migrated and now its Exchange on the backend, but I don't know what values from Outlook I need to input into Thunderbird to make this work. Could someone please guide me on this one? I am currently receiving emails through Outlook which is increasingly a mess since important emails are getting downloaded there, splitting my inboxes between my old Thunderbird and Outlook now.

Thanks in advance,

You need to find out the addresses of the Exchange server's POP3/IMAP and SMTP virtual servers. Usually it is something like "imap.domain.com", "smtp.domain.com"

Thanks I already went through that link but step 11 is not clear, I don't have a server hostname when I look it up in Outlook.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

What is the value for the Exchange server setting in Outlook? Is there an e-mail admin you can ask?

you can also find it by doing this

Nslookup -ty=mx domain.com

If I go under Tools > Account Settings > double click on my email account then I can see the Exchange server, but I don't know the port number to put it in TB. I already tried IMAP port 993 but nothing. I installed Exquilla plugin and entered the OWA URL which succeded, however I can't get emails... If I try to log into the OWA website, I cannot connect. I think I must pursue this path and maybe that plugin will do the trick?

You need to check with the exchange admin to see if they are running IMAP or Pop3.

They do not run by default and if you do not have a need for Imap or pop3 then the services are not active. Requires some configuration on the exchange side.

So check with them first.

OWA is working for some users, I will have to ask them to review my access privileges. I don't see traffic on IMAP or POP when running a packet capture.

The solution was to use HTTPS access to connect to the Exchange server instead of using POP3 or SMTP.
