Still the same setup as last year: MS Outlook at work OE Classic Pro at home plus PopMan as an email notifier
On my laptop [W10] Outlook and PopPeeper. Used to be ePrompter but when developer abandoned it 3 years ago there was not much choice. For my desktop [Mint 18.3] it's Thunderbird and NO notifier - because this is an constant problem with Linux after you switch from Windows.
I use Outlook at work. At home on my Windows 10 setup Outlook as well, Thunderbird on Linux. I make use of Outlook's calendar for appointments and such only at work. At home I only need a basic email client.
I've been using POP Peeper for longer than I can remember. Along with Outlook, of course. POP Peeper can handle any type of email account that I can think of. By the way, in my opinion the Pro version is unnecessary, although a while ago I purchased it to support the developer. But I don't use those features.
