Provider Epcan set up POP3/IMAP and SMTP. I did a test with this configuration by android mailapp. I did not use the Exchange workflow. But i will test with the add on's. Thanks

Yes and there is my problem

Your name: should be your name not an email address. Username: this is usually your full email address, but sometimes it is the first part before the @, so try full email address. Password is the same one you use to access webmail.

the server name you have: 'web.epcan.mail', looks like what is used to access webmail va browser eg: https://web.epcan.email/login.php and not access server for imap.

If you logon to your webmail account, is there anything about selecting imap or pop or even what to use for server settings in email clients?

Updated info...been searching...Located info: Access by phone info talks about clicking on 'Exchange' to set up account. Klicken Sie auf die Option „Exchange“ (Bild 1) – Tippen Sie ihre E-Mail-Adresse und das dazugehörige Kennwort ein. (Bild 2) Also: found and translated this: We operate our own Microsoft Exchange farm on our redundant server and storage systems.......

So it seems you can get access but via Microsoft Exchange... You may need to ask the epcan admin whether imap and smtp is switched on for you. Perhaps it is currently disabled.

Maybe those server settings will work but only via exchange.

Located some info posted by Zenos: Thunderbird doesn't have this proprietary protocol. I use an Exchange account myself, but it has POP, IMAP and SMTP enabled, so I can use it like any regular standards-compliant email account. If your Exchange server doesn't have these standard protocols enabled, you made need an add-on.

Whilst I've located this info, I do not use exchange, so cannot really advise further.

sfhowes can you offer some pointers?

Maybe I was a bit late to the party with info....that's what happens when mother turns up and I'm away from computer for a while :)
