Hello,
I am still using the Opera 12 browser's in-built e-mail client. Since the last couple of weeks I have noticed that it duplicates any email sent from the browser. This does not occurr if I send from Ms Outlook or my smartphone, so I guess it must be something with the browser. During this time span:

• our server admins requried all users to change password (I relate this as some google search results for other IMAP clients suggested this might be due to IMAP synchronization)
• I have temporarily installed and then removed Opera Mail (the separate product)

Thanks fro any help

I have tried through Thunderbird (so I could remove duplicates, through a specific plugin, and correct the folder). Then selected and "saved as mbox" some chunks of the emails. Imported all chunks from former sent folder into sent and all the chunks from former inbox into inbox.
It takes a bit, but seems to work.

Also the one that you made creates multiple files, one for each message. It looks this would not be different than importing accountN folder...Is there any way to avoid this?

Any suggestion for a decent mbox file splitter?

CutMbox is suggested by Thunderbird help pages. The link is supposed to be http://apveening.a61.nl/software/, but that's no longer active. I found it on Google at http://priede.bf.lu.lv/ftp/pub/Internets/pasts/CutMbox/, but I did not try it or anything.

I have one here that I made as a toy a long time ago. No guarantees on accuracy or anything, but you can try it to at least test how things go.

Thanks, but this seems to generate a miriad of mbx files equal to the number of messages, if I did not get it wrong. It would be equal to importing the accountN folder then.
I was hoping to fing a mbs splitter allowing to break the 5 gb files in, say, 4-5 chunks...

Update:
I have tried to see whether Opera 12 reads the entire accountN folder. It does it relatively fast (after like a 5' freeze). However, I cannot see any sent folder. It only allows to dropdown select specific .mbs files (I guess the single email files) which is not very useful.

I also tried to install and import in Thunderbird. TB successfully imported the original larg .mbs file...
Still puzzling...

Try this first. After you add the mbs file in the import dialog and it doesn't show up, wait a while. Wait a couple hours if needed. Opera might be processing the file and taking a while because it's so big. If that solves it, note that the actual importing of messages will take a long time after that too.

I tried this but Opera 12 does not seem to react. After I select the file and click open nothing really changes. Opera does not freeze or act as if it is doing anything. I could immediately select another file...
I will try and leave it there for one night, but I doubt it will work.

Should I try to import the entire folder in AppData\Local\Opera\Opera x64\mail\store

The entire accountN folder (where N is the number for the account as seen in accounts.ini), yes. You can try that if the other thing doesn't work.

I think this is my second option. However, I fear I may loose the sent folder as they are not separate in the accountN folder, right? Any suggestions?

Another option is to look for an mbox file splitter on the net that will split the messages out of the large mbs file to separate ones. You can then put all the separate ones in a single folder and import that folder. It'd be kind of like importing from the mail\store\accountN folder. Just like importing from the accountN folder, it might be easier for Opera to process.

I will leave this a s third best. Any suggestion for a decent mbox file splitter?

Thanks burnout426.
It's just two .mbs files about 5,5 Gb each.
I tried to open one in a text editor with no problems. The text was kind of messy but still recognizable.
I have successfully imported this old account years ago, but I cannot remember how...Should I try to import the entire folder in AppData\Local\Opera\Opera x64\mail\store? Should I re-export it?

Hello,
I am migrating to a new laptop and still using successfully Opera 12 as a mail client.
I have successfully set up my current IMAP account. I wanted (and have already done several times) to import also a set of very old emails (in my current laptop as a separate POP account).
I have exported inbox and sent as .mbs files, opened Opera/File/Import and export/Import Mail/Import generic mbox files/selected one of the two mbs files... and... I cannot go on. The file does not appear in the box below and the "import" button stays grey and unclicable.
I think I need some help from burnout!
Thanks

Little update:

• even if I remove the "Sent Folder" in Tools/Mail & Chat accounts/Account Properties/IMAP in Opera Mail/standalone after a while (e.g. checking some messages and checking sent messages IMAP folder), the setting goes back and I find again the "sent folder" in Tools/Mail & Chat accounts/Account Properties/IMAP. Thus duplicates start again to appear.
• 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...

Hello and thanks (I think the other thread was me, sorry for duplicating I was unsure whether it was accepted.
I have now installed both Opera mail and Opera standalone. I am making tests with both (frequent crashes when contacting server). Results:

• If I use Opera Mail/standalone with the default "Sent Folder" in Tools/Mail & Chat accounts/Account Properties/IMAP, I do get duplicates in the All messages/sent folder. Duplicates are also created in the original Opera 12, Outlook and smartphone sent folders.

• If in Opera Mail/standalone I remove the "Sent Folder" the duplicates go away. However: sent msgs are not stored in the "Sent messages" IMAP folder but only in All Messages/Sent folder (but still appear in Outlook/smartphone). So if I send a message with Outlook and/or smartphone the sent message will not show in Opera with other sent messages

• ideally I would rather have Opera not to store any copy in the All Messages/Sent folder but just save in the IMAP/Sent Messages folder, like Outlook and smartphone.

Why unchecking "show duplicates" is not an option: the duplicate message is way larger than the original (between x20 and x30 in size, e.g. a text-only, 2.6kb, sent message gets a duplicate of 86kb. Just imagine if I send an attachment) and my mailbox is entirely copied locally and the Opera/Mail folder currently amounts to 47+ Gb. I would not really have it swell at a significantly faster pace.

If needed I can copy the original and duplicate messages' headers

thanks a lot
