First, I am wading into deep water in responding, as I am NOT the super tech guru here. What I am suggesting is that you post the details that can be evaluated, such as screenshots of your incoming and outgoing server settings panes for the account, plus screenshots of the error messages seen. Volunteers need to see exactly what thunderbird has to give potentially useful suggestions. I did spot the Rogers suggested settings

https://www.rogers.com/support/internet/shaw-email/pop-and-imap-email-server-settings#imap-with-ssl-tls   but, from your post, those may not be correct. Once you respond, some suggestions may be offered. As an observation, I have never seen a situation where Thunderbird was the problem when it has been given the proper setup information, so I remain hopeful. :)  Thank you

No support from Thunderbird (except for your help, which I really do appreciate), is sporadic. Without email now day 7. Shaw/Rogers/Whoever, are really trying to push webmail managed by Yahoo. A higher level tech support from Shaw/Rogers was going to call me yesterday or today. Not! Waited both days. No call. But, everything points to Thunderbird being the problem.

I read a lot of questions here who need Thunderbird help involving Shaw/Rogers issues.

After all these years with Thunderbird - have been great. I hate to uninstall it, but without Thunderbird head kahunas fixing the problem, I will not throw myself to the trackers, stalkers ad nauseum with webmail.

I confess I did (out of dire need) use webmail for one account and found that I missed a heat specialist appointment. They charged me $50.00 for not showing up.

I feel Shaw, Rogers, have one thing as a goal, to goad, bully and shove everyone in to webmail.

C'est la vie & Caveat Emptor,

Thanks David,

ps. If I find a way to keep and am able to maintain my rights to privacy using Thunderbird, I'll let this forum know. ~r

I will see if I can get someone with more expertise to look at this.

I asked Rogers and Shaw expect people to drop all their existing login IDs (which most sites require when registering) and switch them from myname@ to myname432cv like a Gmail account. Depending what tech support I reach, each has a different answer - some say yes, some say no.

They said I should use webmail. That means, if Thunderbird has more than 1 email account (I have or had, 10 emails with Shaw. No one I know that uses Thunderbird were ever notified this would happen Ergo, and they all said yes that I would have to:

1. Log in with email account 1@there.com check for webmail and send reply or not. Then log out of webmail #1, close browser then
2. Open browser again, log in with 2@there.com and the same thing, login etcetera

And, to do that for all 10 accounts. 10 times a day. Some webmails need to be checked every hour, 2 every 15 minutes, some once a day.

I still don't have access to email. To me, webmail is called webmail because it's not email. I need the right to privacy... something Rogers doesn't respect. Respect is earned, not divvied up williy nilly. It's why I've stuck with Thunderbird for years than I can count. I respect Thunderbird. Info miners of webmail, don't deserve respect

Thanks for your time and hope to hear back soon - some good news for a change. : ~r
