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.

As I posted some weeks ago, the problem also occurs on my MBP with external 4K USB-C Monitor:
Hardware:
MBP 2018 15" (Touchbar)
external 4K Monitor LG 27UK850 - defined as primary display
Got the Update to Outlook 16.27 (19071500) yesterday an the problem remains.
In fact it is worse !
After opening Outlook 16.27 after downloading , screen immediately started flashing .
It was posted that Microsoft were looking at resolving the problem ..let's hope .
(bear in mind this issue only applies to late 2015 27" iMacs ..the rest of the iMac world exists in a flash-free world !)
In interim Apple mail works just 100%!!

I have the same exact issue, and I can't even read a single email without my screen is going bananas. The only way to resolve it, is to change screen settings to another resolution and back to standard settings, but as soon as you go back to Outlook again and click on anything, it comes back.
I've been in contact with Outlook support in several cases, even sent them a video demonstrating this issue in detail, but nothing happens. I need Outlook for my work, even if I am working in a Macintosh environment. It surprises me that they resolve issues with badly placed menu items before something that is actually and physically harms your computer?
I have the following hardware:
Mac OS Mojave 10.14.5 (18F132)
iMac (Retina 5K, 27-inch, Late 2015)
4 GHz Intel Core i7
32 GB 1867 MHz DDR3
AMD Radeon R9 M395 2 GB
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
Hi Have already gone all through this with Microsoft, after four or five lengthy phone calls, I was told that Microsoft were aware of the situation, but as it affected such a small number of users I.E only people with late 2015 27 inch IMAC's, that they were not prepared to do anything about it.
I have found that if you run Outlook in low resolution mode the flickering issue stops, its not a good fix but better than nothing.
Cheers
Richard
