I have a big mail archive (about 10GB) from the beginning of 2000x in my Microsoft Outlook Express. This client is very old and sometimes it is not usable to work with it.
I tried to import my mail database to Microsoft Outlook, but unfortunately it supports maximal size of mail database 1GB.
Is there any alternative way to migrate this database to Microsoft Outlook or any open-source analogues like Mozilla Thunderbird?
Please, answer if you have real experience.
Thank you in advance.
