Running Outlook on the iMac causes the screen to flicker and eventually black out and reduce to half/split screen display.

If I don't run the Outlook app the Mac runs like clockwork.

With Outlook active, at some point the flickering begins and then gets progressively worse until the screen is completed fuzzed or it pops back to a half black screen (which continues to flicker intermittently - more often than not)

Whilst it sounds like a hardware issue (and I've ordered a new Mac thinking it was!) it appears to be tied to Outlook.

iMac (Retina 5K, 27-inch, Late 2015)

3.3 GHz Intel Core i5

8 GB 1867 MHz DDR3

AMD Radeon R9 M395 2048 MB

Mac OS 10.14.1 (18B75)

Outlook 16.19

Rebooting seems to clear it until we run Outlook again, then the cycle continues.

    a good news for everyone.

    Hello Pitman,

    I trust this email finds you well.

    I proceeded to escalated the ticket as I found many reporting the flickering issue over the internet.

    At the moment we are investigating. As soon as I have any information I will follow up

    I have exactly the same problem and after scouring the internet, resetting SMC, NVRAM, PRAM and deleting other apps that may be causing the issue I have narrowed it down to Outlook.

    This needs a resolution soon, the issue is obviously with Outlook, not all these Macs that people are having the same problem with.

    My spec:

    Mac (Retina 5K, 27-inch, Late 2015)

    3.2 GHz Intel Core i5

    16 GB 1867 MHz DDR3

    AMD Radeon R9 M390 2 GB

    Mac OS 10.14.5

    Outlook version 16.26
