    Discussion for all: IMAP + Safety

    I was told that it's safer to stay on POP3, than it would be to move to IMAP / Exchange / etc..... I am just wondering if there's any truth in that? Can hackers still get into your mailbox, even with 2 step turned on? Context: I use Fastmail with 2-Step ON with Authenticator App for...

    Outlook 2016 - controlling IMAP OST size with Group Policy not working

    Hi all, I'm trying the Slipstick Forum as this has been quite helpful in the past. Here goes...

    IMAP Folders Dialog Box

    The "Display folders whose names contain:" Query input field in the "IMAP Folders" Dialog Box is case sensitive. To me this makes no sense. And it makes finding a particular folder more difficult. It also seems inconsistent with the way Windows 10 works in general. Does anyone know of some...

    POP3 vs iMAP?

    I want to set up my email so that mail deleted from my phone or laptop is still available for me to see on my home PC, but mail I delete from the home PC (which uses Outlook 2016) will be gone from the other two. It's my understanding that this would require I set up the home machine as POP3...
