Error connection dropped by imap server

[#1]

So I am trying to check the inbox of a plusnet email it's plus.com variant and outlook isn't downloading the emails but neither is emclient, so I logged in via the plusnet wrbmail and I get this error message "Error connection dropped by imap server"
Their second email address works fine via outlook and webmail.

[#2]

Ok so things didn't go exactly to plan, I changed the settings on their two email accounts, one works perfectly but the other one won't display incoming emails
It shows the notification for new message in the bottom right but nothing shows in the inbox and if I click the notification it says "the message you specified cannot be found"

It does this with outlook on two different machines and the emsclient doesn't download the emails either.

If I try and log into their webmail client it says "error connection dropped by imap server"

[#3]

You changed what email settings, from what to what & for what purpose ?

The a/c that is not working in Webmail due to an IMAP server issue, that needs to be resolved first
before expending more time on email clients like Outlook etc.

That hints at the oddity which arises sometimes where one needs to specify the IMAP root folder as inbox

There is also the possibility that there is a very big email queued for synching which is causing the connection to time out.  Set the server connection timeout to 2 minutes.

So I changed the outgoing mail to starttls and port 587, in outlook this worked fine as I sent and received test emails then I get a call today they aren't able to get emails, so I change the security settings and port back to what it was and still no luck.
So then I think to login to their webmail but it won't login, it gives me the error message I mentioned above about imap, surely it it was the fault of the outlook settings I changed then their webmail would be fine to log into?

Anything done on the IMAP client has nothing to do with logging in via webmail.

Get the webmail login working - be clear about the brand (check the provider option box), user ID being used and the password.

Thanks for the quick reply, their details are saved so correct as far as I can tell, it's set to log in as plusnet and their secondary email works in both webmail and outlook

So I just tested sending an email via outlook and it sends fine, it's just receiving (so imap) that seems broken
I have changed root folder path to Inbox but no luck with that

If it was the wrong password in webmail would it give the imap error I mentioned above?

Can you log into each account using webmail?

Webmail can experience connection issues if there’s a massive mailbox or a large mail item.

Hi, sorry about the delay
They got home and gave me the correct details and I was able to login to both of the webmails, however the one I am having problems on wasn't showing any new emails, the last one was at 12:47 yesterday which coincides with the last email they were able to download via outlook but I know they have other emails that should be showing as we have sent test emails from multiple accounts.

[#10]

How have they configured outlook?  POP3 or IMAP?

[#11]

Imap and it was working fine until yesterday

[#12]

Any idea why the new emails aren't showing up in the webmail either?

[#13]

"wasn't showing any new emails"   for a Web Mail client using IMAP this can mean the new emails are not there to see.

Could spam settings or mailbox being full be an issue ?    What is in the SPAM / Junk folders ?

[#14]

A plus.com mailbox does not stop receiving emails when full.

I think Philip nailed it, I deleted stuff out of their deleted folder (I didn't want to randomly delete their emails without checking) and now they are able to receive my test emails but it seems like anything sent in the last 48 hours has been lost.
