My Outlook 2016 "Start Up Options menu" has no drop down submenu

@Gabrrybock,

I apologize it's taking a long time to get a fix for the issue. The Outlook Team is working through some higher impacting issues but should get to this one soon. This issue has a workaround registry setting that should help mitigate it most of the time, documented in the Known Issue article, Outlook unexpectedly prompts to reopen items from your last session - Microsoft Support.

To simplify the workaround, I created the registry key and shared it on OneDrive here, ReopenWindowsOption. The file name is ReopenWindowsOption.reg. You can download it and double click on it to add it to the registry. If you want to double check the file, download it, then right click it and click Open With Notepad. Or open Notepad and drag the reg key to Notepad to see it. After adding the registry key restart Outlook to pick up the change.

Here are the contents of the file ReopenWindowsOption.reg:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Preferences]

"ReopenWindowsOption"=dword:00000001

This problem has been ongoing since the beginning of July. Now the end of August. Microsoft team doesn't have anyone who understands how to back out of changes they made? Who at Microsoft is being held accountable for this problem impacting customers. It should have been resolved the day it was reported.

Is it just me or with Outlook 2016 just in just the past week or so asking for each and every attached file if I want to open this type of file? And of course just like the problem being followed in this thread the option to uncheck this function is grayed out and not accessible on the screen. When a single email has lots of attachments it's almost more annoying than the other prompt we are all still waiting for a fix.

Thanks for the update, rather current M/Soft position Gabriel.

Update Pete - quite agree and I would perhaps be on same level if not a 1 or 2 ... haha!

Confirm the 'work around' by deselecting/unticking Outlook Storage to Cloud still works great for me without the jolly pop-up box etc etc although I do not use Outlook 2016 on other devices thus probably not necessary in my position anyway?

Still no drop down box after Start Up Options obviously, but as Gabriel has advised this will by reactivated by sound of things when M/Soft finalise or sought out the fix!?

Again, I concur that the 'general' end user should not have to muck around with registry keys to fix an update bug which is now some 2 months old, nigh on.

In fact the inherent warning, while 99.90% of us are genuine, of these forums would elude to being cautious about doing so (altering registry or other) for security/cyber breach reasons.

As a matter of interest (following another thread above from 'MrVanish') I have an old business programme designed from Access/Excel etc and since this issue cropped up - when I double click the desktop icon for it, I now get a darn User Account Control (UAC) warning request that it (MSACCESS.EXE) wants to make changes to my PCSystem YES/NO. I went on M/soft Chat and they simply reduced the UAC control to the bottom layer of protection to avoid the UAC pop-up which it does. BUT I asked if it could impact or have any affect on security - they said definately not - in yet isn't that what its for - to warn !!!!????? sheeesh!

Oh well enough for one day.

Cheers

Terry

Hi Gabriel,

Thanks for your prompt reply. I do not consider myself to be accomplished in computing, more of a 2-3 on a scale of 10, and I suppose a lot of people are around my same level. However, I didn't find it too difficult to revert back to 2035, yes it took some time, but the guides put up were really helpful.

I ended up going to from 2035 to 2037 so that any security updates from 2036 & 7 would be bought onboard, a concern raided by Great White North who along with many others has been so helpful.

Perhaps a workaround is to add the security updates from the latest versions to version 2035. That, as I say, is coming from someone out of their depth with such matters.

I forgot to include system information which follows:

Outlook version 2307 (build 16626.20170 click to run)

Device name DESKTOP-AMD

Processor AMD Ryzen 5 3600 6-Core Processor 3.59 GHz
