Opera 12.18 Mail problem in Windows 10 (omailbse.dat)

  • HEy there,.
    just updated to Windows 10. With the update the email failed to initialize in Oper a12.18 (browser and mail client sitll integrated). I keep getting the notice :

    Error While initializing Opera Mail.
    There was a problem initializing Opera Mail.
    The following file appears to be in use by another application: C:\username\Appdata\Local\Opera\Opear\mail\omailbase.dat
    To retry please close the application that uses that file or restart your system.

    Restart of the prog or the system doesn't do anything,, I ran the ccleaner regitry tool but it didn't help either. When I ran the system in safe mode (network) the mail appeared, but didn't work (fetching new emails, or sending).

    The email base is pretty big, and would be a pain to not be able to use it as I did for the last 10 years.

    Any help would be appreciated!


  • ...anybody?

  • It might have been damaged in the upgrade. Have you tried uninstalling and reinstalling it?

  • If that doesn't work, try downloading and installing this utility.
    It will put a right click menu entry on the file which should tell you if it's being locked by another program, and which program it is.

  • What happens if you try to move omailbase.dat to a temp folder?

  • hey guys, thanks for the input!!

    • unfortunately i havent reinstalled the Opera yet as it took forever to backum the latest files (more than a decade of emails), so I had to postpone it for some other time (today if possible)
    • trying the unlocker thingy on omailbase.dat, resulted in the same notification as before (Dave, great app, I tried to find sth like it but couldn't)
    • removing the omailbase.dat from the folder, resulted in the same notification

    I guess the most probable option is that the file has been damged,.. ?

    I guess so.

  • a followup..

    a reinstall and replacing just a basic files did the job (mail, bookmarks, contacts, wand etc..) as far as I could tell the problem was caused by a file from User CSS directory, eg: C:\Users\YOURUSERNAME\AppData\Roaming\Opera\Opera x64\styles\user
    couldn't tell which one though..

    thanks for your help, much appreciated!!
    take care
