Finally I've stopped the very first sync and deleted the GMail account.
All other accounts are working fine.
I've made a bckp and I have to delete all the accounts to keep the Opera Mail settings, then another bckp and readd the Accounts.
Also, because adding GMail again puts GMail not as the default eMail.
I'll try your suggestions as well.
@kalder said in Opera mail client duplicates sent messages:
I am still puzzled about why only Opera (my 12.x version, Opera Mail and standalone) duplicate sent messages, whereas Outlook and smartphone app do not. And why all this started a few weeks ago...
Maybe something changed on the server where the server is no longer ignoring Opera's duplicate and it still ignores other clients' duplicates. And or, maybe some other clients don't add a copy of the sent message if it's an exchange server. I'm not sure. I would guess that for Outlook, it's probably not using IMAP to connect and is using the actual exchange protocols etc. For the smartphone app, I guess maybe look in the settings. It may reveal something.
I'm pretty sure Exchange has been creating its own sent copies for a while, so I doubt that was off and hotmail all of sudden turned it on.
Close down Opera Mail and edit operaprefs.ini. See "Menu -> Help -> About Opera Mail" for the location. Under [User Prefs], make sure "Show Notification For New Messages" is NOT there so that Opera uses the default for the setting (which is 1). You can keep it there and set it to 1 if you want, but do the other way instead. Then, make sure you never mess with the checkbox in the settings UI as it's broken. It's really only broken for unchecking (trying to set it to 0), but just avoid the checkbox for good measure.
That's probably not going to help as you already get notifications sometimes. But, I'd try it just for good measure so that you know the setting is right.
Then, while Opera Mail is closed, for each account in question, check the section for the account in accounts.ini in the mail folder. You want Sound Enabled=1 set and Sound File=path to .wav file (make sure it's a .wav file).
That's probably not going to help either as it sounds like things are set correctly.
Then in the UI under the settings for each account, on the Incoming tab, make sure "Include this account when checking manually" is checked. Make sure "check every..." is checked and set it to less than 30 minutes (and no less than 10 if the server has a problem with you checking too frequently). You need to do that even if you're using IMAP and IDLE so the IDLE connection doesn't time out. You also need to make sure you're not using low-bandwidth mode.
If everything's good and you still have the issue, you're out of luck. It just happens for some people in Opera Mail and no one has ever figured out why.
While Opera is closed, you can add/set Show Attachments Inline=1 under [User Prefs] in operaprefs.ini (see Menu -> Help -> About Opera Mail" for the location).
Just note that option isn't just for printing, it's for viewing too. This means, you'll see the attachment filename in the body when just reading. Also, you might not always see the filename and whether you do or not, the actual content of the attachment might display in the body depending on the type. But, it's something you can try.
Besides that, I'm not sure. You might be able to add something in mime.css in the styles folder in the program files folder. There's an @media print block in there. But, I don't know if that'll help.
On the "Outgoing" tab in each account's properties, there's an "Add contacts from sent messages" options that creates a contact for every person you sent messages to.
Also, if you use the "Follow contact" feature, that can add entries.
Wen you click on one of those addresses, it should show a list of messages with that address, which would tell you were the entry is coming from. But, nothing will be there if the messages were already deleted.
Did you subscribe to any mailing lists that have these contacts? Are there any messages with those contacts in "All Messages/Sent" (name in English locale at least)?
OK. Are these IMAP accounts all with the same provider? If you can set up a free account with another provider and test an IMAP account with it, maybe it'll work for that one and then we can see what's up with your regular ones.
No, of different. I also thought about that But they behave exactly the same.
How do you have your taskbar configured? Anything different than default with your systray icons?
No, standard configuration. And I changed nothing at all - just made IMAP accounts.
Win 7 64x. I also use Avast Free Antivirus but I tried to turn it off completely - no changes.
But, if you're done messing around, I'd just use Thunderbird.
I thought about that. For the last week I tried: Mailbird, Postbox, eM Client, Mozilla Thunderbird - but I didn't like them.
Mailbird and eM Client are great (though they cost some money) but they do not have RSS-reader. Mozilla Thunderbird has RSS reader but this program looks totally different than Opera Mail. i tried to work with it but... I can't. I so got used to Opera Mail that I think it is the most comfortable, effective and simple client in the world. Can you imagine how upset I am? Today I will install Outlook 2013 - may be it will be good.
By the way, if Opera Mail takes about 70-80Mb of system memory, Mailbird and eM Client take 130-150 and even more Mb ((
Are the messages in "All Messages/Outbox"?
Try retyping your username and password on the "Servers" tab in the account's properties.
You can check the outgoing log to see what the error is.
On the servers tab in the accounts properties, TLS should be checked and the outgoing server port should be 465 or 587.
IMAP or POP? On POP mails, Opera expects to keep copies even after they are removed from the server, so there would be nothing new here. For IMAP Opera would need to be set to download and keep local copies of the messages (which would take a little time for 5000 messages) and then would require the user to actually move them to a different account so that they won't disappear when removed from the server.
Too vague for me to say "how", but sure it can be done. You can create folders where you need to manually place stuff in them, folders defined by rules (messages from Julie about kitties, say), or Opera also has learning filters.
