To be clear, I seriously doubt the problems I am encountering are TB's fault! The problems may be my fault since I've grown older, I've tended (believed) using new versions of software present my mind a BIGGER challenge than using the older software/version I have been successfully using? I'm still using Version115.10.1

After our ISP chose to start using Zimbra Oct. 7, 2025 and their tech support could not assist me in getting TB working the had me remove POP3 settings for TB and change to IMAP with their software.

FINALLY someone helped me get TB working with IMAP. For 3 days grrr. Now the ISP says I need to use their web mail, Zimbra.

So might downloading the current TB version and somehow get the In box, all the folder contnets etc. over - into the new TB help?

I was going to backup everything tonight, now I have little to NO hope, without help!

THANKS & remain WELL plus be SAFE!

Hi, Robin,

Please provide more details. My understanding is that IMAP works, so are you downloading messages so you can switch to another email provider? Please explain and we can go from there. Nice to see you again. :) david

David 'n ALL,

Oct. 7 I started getting the following response when trying to send e-mail using TB 115.10.1 (32 bit, Sony Vaio SVE 17122CXB (64 bit) Sending of the message failed. An error occurred while sending mail. The mail server responded: [F1-Auth] Authentication Required, must login.. Please verify that your email address is correct in your account settings and try again. Our ISP could NOT help. Wanted me to use Zimbra (which seems to be ?junk?! I still cannot send messages. Iam logged in/on sincee I have no trouble getting messages. The ISP won't help with TB.

If TB won't work - function after all these years, I need to know NOW! I have to get SEND to work or scrap TB.

Following up on David's previous reply: "Please provide more details. My understanding is that IMAP works, so are you downloading messages so you can switch to another email provider? Please explain and we can go from there."

David, yes, apparently IMAP 'works' for getting mail with TB.

I am paying our ISP & have been for e-mail for over 20 years. Thus, I shouldn't have to (nor do I want to learn a new ISP's system)!

I am stymied why I recently have SO MANY problems! I dare not move years of incomplete - ?corrupted? messages to the new Win 11 laptop (used, not 'new').

All remain WELL & be SAFE!

Robin
