The registry fix shown above worked great for me too, but see the CAVEAT below.
Also, two updates/corrections to it are listed below (underlined and bolded):
The computer with outlook 2007\2010
- Type REGEDIT and go to
- HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\
- Right click on the profile and choose Export and choose location.
The computer with outlook 2013
- Right click on the exported file edit (notepad).
- In notepad click Edit and then replace.
- In the first line put
- HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook
- In the second line put
- HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Profiles\Outlook
- Click replace all, and save the file.
- Make sure your outlook profile name is '
Outlook ' this is the default name
- Double-click the new .REG file to import the edited .REG file into the registry.
- Now you can open outlook and see all the pop accounts the only thing you need to do is put the passwords back and thats it.
- If you have 'unknown error ' try removing your exchange mailbox and set it up from start (the pop account might try to use this mailbox and only after you set it up from beginning it will work correctly)
CAVEAT: This procedure left my "Rules and Alerts" in a corrupted state. Now when I click "Rules and Alerts", to confirm it imported my Rules and Alerts from Outlook 2010 on my old Windows7 PC, I get "the operation failed because of a registry or installation
problem. Restart or reinstall Office". So I tried repairing MS-Office Pro 2013 from the installation disc, but it still gets the same error message! Sheesh!
