Suddenly cannot send or receive email using thunderbird

[dezza]

I have used thunderbird for years with 4-5 different email accounts.

Weeks ago it stoped working for my tpg account only.

All other accounts are working fine.

I have tried everything I can think of, and everything suggested online.

This includes removing and setting up account, probably 3 times.

Thunderbird error is:

Unable to log into server. Probably wrong configuration,username or password.

I have tied various port settings and server names with no luck.

This is strange as I never changed anything that could make this happen.

Does anyone have suggestions please.

Regards

This happened to my email too, however, I tested it working with their Post Office but not on my Outlook Email. I changed my TPG password, re-configure the email after 15-30mins and it did the trick. 

I'm not even sure if this is related with the guide I found here https://community.tpg.com.au/t5/Broadband-Internet/Cannot-Send-Email-Rejected-by-the-Server-Banned-f....

Same problem. Someone said it will resolve itself eventually. I will use the Post Office app for now and recheck when the NBN is funtioning.
