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.

I installed 10.14.6 this morning, and since that, no problem with outlook 16.27 in high resolution !
I keep crossing my fingers 🤞, but it seems to solve the issue.

Likewise. The issue has finally resolved itself with this update.
I was too optimistic, the issue is not solved with 10.14.6 :(
On my side, the probleme occured after a bigger amount of time of use, but it still occured :/
Back to low resolution mode...
I have been experimenting with this issue for months.
The problem seems to be with my iMac default resolution of 2560x1440. If i change the resolution up or down, I get no more flickering.
I set my resolution to 2880x1620 and its working fine.
I have to say that the performance of Outlook is really really slow, especially after I upgraded 10.14. Its been a disaster ever since as my whole iMac is suffering from a performance ever since the upgrade. Thats for another post.
