For some reason, my brain was thinking the file needed rebuilt, not that it was a screen draw error. Sorry. :( 50 lashes with a wet noodle for me.

I'm assuming opening a second outlook window would redraw it too? (right click > open new window)

Have you tried enabling "Disable hardware graphics acceleration" in file > options > advanced. (near the bottom)

The signs are good - so far no recurrence of the issue. If you don't hear from me again on the matter, assume it is fixed. Many thanks

We use Symantec Endpoint Protection. No backup application that I'm aware of. I boot my computer first thing in the morning and shutdown at the end of the work day. So, Outlook is cycled regularly.

For me, the problem happens randomly. Sometimes I'll go a couple days without it happening. Then I'll have a day where it will occur at least 5-10 times. I can "resolve" the issue by slowly dragging my mouse down the blank list and each folder will appear when the cursor gets there. Or, sometimes switching to another view (e.g. calendar) and back will cause the whole list to pop back.

This would suggest it's not linked to anti-virus, because I would expect it to happen on a regular basis if that were the case. And, since I don't have backup software running (we use one drive), that's would appear to be out as well.


I should try your method. Thanks

I also had the folder draw problem. It began soon after I switched from Office 2016 to Office 365 in late October 2019. Installing the latest graphics driver did not help. A couple of weeks ago, I searched the web and found your advice, which worked perfectly.

As an experiment, I alternated several times between having hardware graphics acceleration turned on and off," and found that the redraw problem always returned with it on.

Thank you for your excellent advice.

I have been having the same issues as the OP. Will try this solution too.

One workaround I had found was to simply reduce the width of the folder pane to zero by dragging with a mouse and expanding back out again. That triggers redrawing the folder pane with all its unread counts.

This happens only to the folder pane, and it makes me think that this is a deep bug somewhere within the Outlook software that is rendering the UI. Disabling hardware acceleration may only be hiding the issue.

If I was trying to troubleshoot this, I would create a 2nd profile, with only one email account in it.
I would NOT want that to be a Google account, and ideally just for purposes of this test, i would want it to be POP3.
And see if the issue still occurs.

I am using Outlook 365 on Windows 10 64bit all up to date with the latest updates.

My issue is that regularly (a number of times a day) the list of folders in the folder pane clears. Sometimes everything disappears, sometimes the odd folder remains. When I mouse over the list, it refreshes but often doesn't show the number of unread items in a folder. Sometimes clicking on a visible folder refreshes the whole list, sometimes not. The only sure way the refresh the list properly is to select, say the calendar, and then return to mail. This has been happening for months and I have been trawling the internet for a solution, but I have seen nothing similar. There is nothing weird about my set up that I am aware of. I have 6 IMAP accounts listed along with the default Outlook.

Recently I was forced into doing a clean install of Windows 10 and a fresh install of Office 365 to go with it. I was sure that would cure any glitches that had crept into the machine, but NO, shortly after installing afresh it came back. Here is an image of the partial list:

Any suggestions as to what is going on here and how to stop it?
I have exactly the same issue which lead me here... so it's not quite such a one off
