Thunderbird, Office365, GMail and Avast
« on: January 18, 2022, 11:29:48 PM »
I've been using Thunderbird as my central email point for years. Different email addresses from different hosts, etc. -- all fine.
About a year ago, GoDaddy "upgraded" my personal domain's email to Office365. Managed to survive; all still working, though I couldn't add a new email on my domain to Thunderbird.
This week, I'm told I have to update other details because MS is requiring Exchange (or something like that), and third-party email clients won't work right any more.
Talked with GoDaddy support for over an hour trying to get it all working. Based on his research and our trial-and-error, all of the incoming and outgoing server settings seem to be working -- but only if the Avast shields are disabled. This only seems to happen for the office365.com and googlemail.com domains. The others work fine with shields up.
Am I missing something?

Incoming Server Type: POP
Server Name: outlook.office365.com:995
Security: SSL/TLS
Authentication: Normal password

Outgoing SMTP Server: smtp.office365.com:587
Security: STARTTLS
Authentication: Normal password

===

Incoming Server Type: IMAP
Server name: imap.googlemail.com:993
Security: SSL/TLS
Authentication: Normal password

Outgoing SMTP Server: smtp.googlemail.com:465
Security: SSL/TLS
Authentication: Normal password

That seems to have done the trick. Thank you!

Hi,
I'm having problems with downloading emails from various mail servers into Thunderbird (latest version, but also previous versions). When I deactivate the AVAST mail shield everything works fine, but when it is active no emails are downloaded. I tried the tip given above about reconfiguring IPv6 in Thunderbird, but this hasn't changed anything. I also de-installed and re-installed Thunderbird from scratch, but still no change. Any ideas?
Thanks
DG

Hi Bob, if you mean the link posted earlier in this thread by r@vast, then yes, I tried that - but without success.

I think I've fixed the problems by following the advice given here: https://support.avast.com/en-ww/article/91/

The only difference I found was that I couldn't import the mailshield certificate as stated because I already had several AVAST mailshield certificates installed. I deleted these existing certificates and then imported the mailshield as per instructions.
