    Outlook 365 blocked by Google popup

    When opened, OL365 is immediately obscured by a popup asking for Gmail login. When I log in to my valid Gmail account, a second dialog asks about sharing data between OL and Gmail. When I approve that, I quickly get a window : Sorry, we could not sign you in to google-IMAP. Try again later." If...

    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...

    Outlook 2016 crashes at start

    I just recovered from a system crash a day or two back. I think Outlook worked OK the day after that (I'm not sure), but now it crashes within seconds of starting. I am running the Office 2016 version, in Win 10 Pro x64, with the account set up as IMAP. I had thought, based on experience when...

    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...
