Odd email behaviour?

[#1]

Yet another day with multiple duplicates

@plusnettony 

I wonder if there is a solution to this at all??? 

[#2]

Right!

Today again another round of duplicated emails which as far as I can tell are both very recent i.e. including today & not yet deleted and deleted ones from the past 10 days or so.

This was the greater part of 1024 emails received the one mailbox that has seen the previously reported duplications.

@plusnettony I wonder can you please throw any light on this annoying behaviour?

This can be a characteristic of using a POP3 client.  If the POP3 and the server gets the index out of sync, the POP3 will down load them again.

Unless an IMAP client (such as webmail) shows duplicate emails … there are no duplicate emails: the client has simply chosen to download them multiple times.

Hi @Townman 

Thanks for the insight.

Yes, I am using POP3

AS mentioned IIRC previously this started relatively recently whilst I was using  Outlook 2007 and various replies advised that due the nature of the older programs security that might be a source of the issue.  I happily updated to Outlook 2024 and the problem persists.

So, I suppose the mystery is what is it about Outlook 2024 and 2007 before it would start to have this problem in one particular mailbox?

I take your point about it for some reason downloading copies but also as mentioned even when I have deleted the emails locally and my Outlook settings are to once once deleted locally 'remove from the server' i.e. it should no longer exist on the server to download

Are there any Outlook settings that I should be examining?
