... how to soar with Opera...

Migrating email, news and feeds from one Opera installation to another

, ,

If you are in the habit of installing the various previews and test releases that Opera comes up with periodically; or simply like to do a fresh, clean install of Opera when you upgrade to the next public release; one of the concerns is how to migrate your messages (email, news and newsfeeds). Following is a simple procedure that describes what to do.

Note that this description only applies when your new Opera installation is pristine (i.e. you have no email, news or newsfeed messages set up in the new Opera install).

Also note that the mail storage format is different in Opera 9 compared to Opera 8.xx. If you need to migrate an Opera 9 mail setup back to Opera 8.xx, this method will not work. In that case, you must export your Sent and Received messages in Opera 9 and import them back into Opera 8.xx.


  1. In your old Opera installation, look at Help > About Opera and note the path to your 'Mail directory'
  2. Do the same for your new Opera installation (if 'Mail directory' is not found in Help > About Opera, note the location of the 'Opera directory' -- this is your Opera profile folder)
  3. Close all instances of Opera
  4. Rename the Mail directory for the new Opera
  5. Copy the old Mail directory in its place (if the new Opera did not have a Mail directory, copy the old Mail directory and place it next to the profile folder)
  6. Start the new Opera

If you already have some mail in the new Opera installation, your best recourse is to export the messages from your old Opera installation and import them into the new Opera installation.

You can import and export newsfeeds quite easily using the File > Import and Export... menu. For mail / news messages, see below.

Do the following in your old Opera installation:
  1. Right-click in the Mail panel, and set 'Show messages from' to one account
  2. Open the Received filter message list
  3. In the mail toolbar, enable all the View > Show > Show *** settings
  4. In the Mail panel, right-click on Received and select Export...
  5. In the resulting dialog, select an appropriate directory and filename for the exported message (e.g. AccountName_Received.mbs in the Desktop directory, where AccountName is the name of the account) and export the messages
  6. Repeat steps 2-5, replacing Received with Sent
  7. Repeat steps 1-6 for all accounts

You can now import these files into the new Opera installation using File > Import and Export >> Import mail >> Import generic mbox file. Remember to import the messages to the appropriate accounts, and to 'Move to Sent' the sent message files.

Yes, thank you. I've posted a request for assistance on this topic in the forums at:

http://my.opera.com/community/forums/topic.dml?id=117764

I am attaching my further query, reproduced in part below, in case the link has difficulty working, so that the reader of this topic can read it without having to go to the other page.


QUESTION, RE: bringing back the data contained in subfolders.


I have the main inbox and data. I have the subfolders by title. By clicking on the subfolder icon, I get nuthin' - nada - zip - zilch.

What I had done was to save the existing Opera directory to another directory, say, by way of illustration "F:\Opera_a" for 'archive.'

In the new machine, do a clean install of that very same version of Opera, in this case, Opera ver. 6.05

Then, go to newly-installed "C:\Opera" directory and delete the new default "C:\Opera\Mail" subdirectory.

Next, go to "F:\Opera_a\Mail" and copy to "C:\Opera" -- it then takes the space of the deleted default Mail directory.

Also, import and overwrite all the new default "*.adr" files from the old to the new directory.

What makes this complicated was that I had 2 POP3 accounts, for sake of argument, "Account1" and "Account2"

When I clicked on Opera's overhead menu on "e-mail" to invoke the Hotlist, instead of the normal hotlist being invoked, a box at the hotlist was added, from which you could select from "Account1" or "Account2" with "Account1" being the default.

In the *.ini files in C:\Opera, the address of each account had to be identified.

Then, within each "Account1" and "Account2" you similarly had to modify the *.ini files to tell Opera where to look for each account and subfolders.

For instance, in the C:\Opera\Mail\accounts.ini, the syntax would be:

[SETTINGS]
DefaultEncoding=windows-1252
ActiveAccount==?windows-1252?B?account2?=
[ACCOUNTS]
=?windows-1252?B?account1?=
=?windows-1252?B?account2?=

Within each account subdirectory, you would have to similarly identify to the new Opera in account.ini and folder.ini folders the fact that you had two POP3 accounts. I would imagine that the same would hold true even if an IMAP account.

The difficulty lies in getting the syntax to have Opera recognize the contents of each accounts ***subfolders.***

Please respond directly to x_soldat on the browsermail service that rhymes with woo-hoo!

Thanks folks,

Happy New Year

> Rename the Mail directory for the new Opera

Rename to what?

[brus]It does not matter -- you can rename it to whatever you want; it is no longer used. You could even delete it if you wish.

I have been running Opera 9 on XP and have to move all my mail to a new computer also running XP. I have installed Opera 9.2 on the new computer. I have tried to move my old mail and cannot get it work.

On my old computer Opera Help About lists the mail location as follows:

C:\Documents and Settings\David\Application Data\Opera\opera7\Mail\

In that folder there are several folders and a bunch of files. One folder is called "storage". It seems to have lots of mbox files from 2003 and 2004 all called mboxXX.mbs. The entire Mail folder is about 1GB in size, of which "storage" is only 80 MB. Most of the 1 GB is in a folder called "Store".

If I copy this entire folder called "Mail" to my new computer and put it in

C:\Documents and Settings\David\Application Data\Opera\

will my old mail appear when I restart Opera?

Along with the "Mail" folder in the Opera7 directory there is another folders called "profile". What will happen if I copy this folder to the same directory?

Thanks

[Birdjaguar] You will first need to close Opera, and remove / rename C:\Documents and Settings\David\Application Data\Opera\Mail\. Then copy the C:\Documents and Settings\David\Application Data\Opera\opera7\Mail\ in its place. When you start Opera, your old mail will appear again.

Regarding the profile folder, see http://my.opera.com/neeraj_deshmukh/blog/show.dml/6579

Quote from top: "Note that this description only applies when your new Opera installation is pristine (i.e. you have no email, news or newsfeed messages set up in the new Opera install)."

What if this does not apply? How can I import mails from one Opera installation into another that already has mails in it, too?

I tried the "import generic mbox" option, but in the source Opera installation (9.2) it seems that every mail is a single mbox file, so do I have to import the emails one by one? Or is there an easier way?

Thanks for help!

(Ignore this post. I forgot to check "Notify me if someone replies to the comment", this time I've checked it. I don't know how to subscribe to this thread after posting, because I don't see the "subscribe" button that is there usually in the forums.)

[Zoominee] I have updated the blog post with instructions for you.

Thank you! I forgot to look in the "right-click a filter menu", I thought that the Export command would be in the File menu. Everything in Opera is so easy after you've done it for the first time!

What about importing e-mails from another client? I just tried out the new Windows Live Mail beta which can export individual mails into .EML files, but I found no option in Opera 9.2 to import these files.

However, individual .EML files look quite much like individual .MBS (just by reading them with a text editor), so I renamed a test .EML file as .MBS and Opera can open and show it.

So I tried importing this .MBS with the "Import a generic mbox file" wizard, but the damn window never enables the Import button!

How does this wizard work at all?!

[fesquivel] .eml is not the same as .mbs, even if they look quite similar. You can use a tool to convert .eml to .mbs, and then import the .mbs files into Opera.
