Office 2016 keeps reverting color theme back to Colorful

Hello!

Thanks for posting on the Microsoft Community, and we're sorry that you're experiencing this issue. We have identified the source of this problem and our engineering team is working on a fix. I'll post back once the update containing the fix is released.

Thanks,

Well, its been over 2 years now (3/4/16, your post to 4/25/18 now) and the problem still hasn't been resolved.  I installed 2016 about 3 weeks ago and use the "Dark Gray" theme.  I turn-off my computer at night and every morning the theme resets to "Colorful."

Also, I agree with another post that the icons on the Dark Gray and Black themes should be normal colored; not white.  It may look cool, which is debatable, but not very functional.  I struggle to identify the icons in white.  Please change them back or at least make an option to have them normal or white.

Finally, in the "Black" theme, this would be my favorite choice except I can't use it because of the poor color scheme of the reminders in Outlook.  They are light gray on white which is very difficult if not impossible to read.  A reminder is supposed to poop; this color combo is a dud.

I was having the issue and I found that when I opened up Outlook and clicked on File ---> Office Account (using Windows 10, Office 365 account), I noticed that it said there was a problem with my Office account on my PC and it had a "Fix It" button. Once I clicked that and logged in with my company credentials, my Office account was fixed and once I set my colors back to black, it has held my colors ever since. Now when I open up Outlook or Word, I no longer have to go back into the Options and change my colors. I know that changing the colors every time you log in is a pain in the you know what so try this and see if that fixes your issue.

Office 2016 client and Office 365, which is online, should have nothing to do with each other. I own Office 2016 but not a 365 account.  I cannot select the dark theme as an option.  I use dark grey.  It seems the Dark theme is only available to those who have a 365 account, which makes no sense to me.

However, I am glad that at least a solution is available a select group of us.

I will try that and see. Thank you

That solved it.  Thank you!
