Fortunately, the time of POP3 connectors for Exchange is over. However, you can still find programs like POPcon from time to time that pick up mails from the provider and deliver them to Exchange. I don't necessarily think much of such tools, but I have to admit that I also use them privately to pick up my mails and deliver them to Exchange. I would no longer use it in the company... Anyway, POPcon can normally be easily migrated from one server to another, as long as it is the same processor architecture, simply export the registry key and insert it again on the new server after installation. done. When changing architecture, this works in principle in the same way, but a small intermediate step must be carried out. Here is a short guide:
First export the key "HKLM\Software\Popcon" on the old server and copy the .REG file to the new server
The .REG file has approximately this content, there is also the source path from where the keys were exported (HKEY_LOCAL_MACHINE\SOFTWARE\POPcon)
On a 64-bit Windows, however, the path must be adjusted so that POPcon can find its settings in the registry.
After the settings have been exported, POPcon can be installed on the new server, POPcon then creates its registry values under the key "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\POPcon"
The "POPcon" key can be selected directly under "Wow6432Node" and the key name can be copied after opening the context menu
The REG file can now be opened with an editor such as Notepad and the old path "HKEY_LOCAL_MACHINE\SOFTWARE\POPcon" can be replaced with "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\POPcon" using Find/Replace under "Edit".
Save the .REG file, close it and merge it with the registry by double-clicking. Done. All settings, mailboxes and even the license have been transferred. Now just don't forget to enter the new Exchange server in the POPcon settings if necessary.
