Backup webmail to .pst file
We recently made MS 365 our email software. We're trying to backup our emails from all accounts so we can upload them to Outlook. When I try to backup from Horde, it only gives me the option to save it as a MBOX file or MBOX zip file and I need a .pst file. Additionally, even when I try to save as a MBOX file it doesn't work (website doesn't load and gets error message). Can anyone help with that?
