I installed Thunderbird to consolidate the many emails I have, of which there are 3 Microsoft 365 accounts. I have been able to load all 3 but can only get the outlook.com account to receive and send. The other 2 which are @companyname.com accounts will not send emails. I have tried the solutions in the help database with regards to having the multiple of the same SMTP servers and the "Normal Password" vs OAUTH2 but to no avail. Any suggestions will be greatly appreciated. My Gmail, multiple Yahoo acounts and Digital Pacific accounts all work fine.

Chosen solution

is SMTP actually enabled on your company site?

SMTP while is is the "standard" is not used by Outlook the mail client and Microsoft routinely disable SMTP on exchange by default as a result. They really want to you only use their products.

You might also surface more information about what is happening by logging the SMTP attempt to send. See https://wiki.mozilla.org/MailNews:Logging#Thunderbird_Logging_Types

Once you have a log, you can right click to copy all and paste it into a reply here. Note the error console is messy and should be cleared using the trash can icon on it's toolbar as soon as it is opened (Ctrl+Shift+J) then the attempt to send mail and then the copy, that should minimize unrelated information in the log.

Thanks for your response Matt, you were spot on, given one of the accounts is for my business I was able to go in and change the SMTP setting and bingo it started to work. The other is a clients mail which is rarely used so I won't bother I think. Once again thanks for your help. Cheers James
