Outgoing emails not sending

[Juliette1]

I have bt email interfacing with Outlook ( have had for 20+ years) ; After setting up another email address with proton mail I was sending emails from my outlook to proton and after a while they stuck in my outbox. I deleted them but since then my outbox will not send anything. 

I've checked all IMAP/ SMTP settings multiple times - all ok. I've updated my microsoft Office to Microsoft 365 , I've backed up my outlook email , deleted my account and tried to reinstate but I get the same issue every time that the SMTP server drops. My webmail is working.

I even installed Thunderbird to use instead of Outlook but this gives me this error: Sending of the message failed.
An error occurred while sending mail. The mail server responded: Too many messages (2.3.2.2) from 159.26.106.134. Please check the message and try again.

I've tried using / not using VPN but I still get the same problem.

I'm not sure whether the 'too many messages' is because I was transferring emails across to Proton ( but actually not that many - perhaps 40/ 50) but then I don't understand why my webmail would work if perhaps I have been restricted.

Can anyone help me please?

You a current BT customer ?

Are you presently a BT Broadband customer or are you paying for your email through a BT Premium email account or did you migrate to EE Broadband?

If none of the above your email account may have been downgraded to a BTMail Basic account which can not be used with an email client or email apps.

Yes

[gg30340]

Yes to which?

[Juliette1]

Sorry - yes to being a bt customer. 

My email is linked through our business account where we are a customer of BT so I can't think that it has been downgraded - I linked it many years ago when BT started charging.

as you are using a business account then you need to post here  https://business.forums.bt.com/   as this forum is for residential customers

Just to be sure it has not been downgraded can you check on your MyBT > My Products > Email, Manage. At the top of the page it should show the Account Type as "Standard".

If it is still showing as Standard it may be that the BT system has for blocked your email account suspecting it to be spamming  due to the number of emails that you have been sending from the BT email account to the Proton account.

If that is the case it may clear itself but I suspect you will need to call the BT on 0330.1234.150 and ask for the BTMail Team and ask them to unblock it.

For information if you have both the BT and Proton email accounts set up in Outlook you should be able just to drag and drop the BT emails into the Proton account Inbox or you could set up a "BT" folder to drop them into.

Thank you - this is really helpful

Thank you - I didn't realise as been going in circles so will try there. I do actually use the email as a personal email but just linked through our business so I didn't have to pay the monthly fee! 😉
