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

Anonymous

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 don’t consider the work around appropriate. It’s hard to look at.

How is this not fixed?

Because it only seems to affect one model of computer that hasn't been sold since June 2017. I don't see Microsoft, AMD, and Apple spending the time, money, and other resources to get together and release a software or hardware patch for this issue when there is a workaround.

Agree - regretfully you are 100% correct .

Time to move on -I have migrated to Apple Mail .

I fortunately can and not tied in to Outlook like some !

My problem in essence is solved .

Thanks for the tip. I did what you recommended as a workaround and so far no flickering...but boy..it looks TERRIBLE/AWFUL (blurry text, pixelated, etc.). Can’t do it.

What I have done is stepped UP the resolution (default is 2560 x 1440) to 2880 X 1620. So far so good. Weird right. Something about the default display doesn’t sit right with Outlook. Will let you know if this resolves it.

Right after the June 11, 2019 release of version 16.26, I had two late 2015 iMacs that started to flicker.

4.0GHz Quad-Core Intel Core i7

16GB 1867MHz DDR3 SDRAM

AMD Radeon R9 M390 with 2GB

OS X 10.14.5

4.0GHz Quad-Core Intel Core i7

16GB 1867MHz DDR3 SDRAM

AMD Radeon R9 M395 with 2GB

OS X 10.14.5

The first iMac was flickering a lot more. I ended up taking it to an Apple store where they kept it and ran several long tests and reported that nothing was wrong with the hardware. They reformatted the drive, and I reinstalled Office and the flickering returned. I kept narrowing down possibilities, and on both iMacs, we later noted that the flickering occurred when the Outlook client was running.

Simply restarting, and not using Outlook, the flickering DOES NOT happen. This morning, out of habit, the users started Outlook and both iMacs began flickering.

I have had both users to go webmail, however, I just read that putting the application in low-resolution solves the flicker for others (which we’re currently trying and I’ll report back on, and yes, it looks lousy).

I hope that Microsoft will resolve this issue with the update.

I have got the same problem too. I have sent an email to Office 365 support and they said this is their first time to heard about this issue. It seems that this forum is more professional than the engineer in Microsoft.

They suggest us to lower the resolution but this is no the answer I want to have.

Are there anyone has come up to a real solution yet? If so, please kindly share.

Thank you!
