Unable to attach file to new message in Outlook 2016

    Question

  • We have just moved to Office 365 for Business and upgraded Outlook to 2016.

    When composing a New Message, click on Attach File and a dropdown list appears of recent items, but only for about 1 second. If you're quick enough you might spot the file you want to attach and click on it in time, but mostly you can't.

  • Hi,

    Does this issue happen to other drop-down menus in Outlook? If so, we may consider to change to another mouse and update the mouse driver to see if it helps.

    Please try starting Outlook in safe mode and then check if this issue continues. This could help us to determine if this issue is related to problematic add-in.

    In addition, do you have any virus scanner installed? If so, please try temporarily disable it and then check if this issue persists.

    We may also try testing this issue in a new Outlook mail profile. This doesn't require you to remove current profile, if the new profile would not fix the issue, we can just change back to your original profile. You won't lose any data.

  • I have the same identical problem. Would appreciate help to resolve it.

  • I was playing around with this further and see that it has something to do with Outlook's "updating" of the drop down list.  When it says "updating" in the top right corner the box quickly rolls back up.  When it doesn't say "updating" it stays down.

  • I'm having this same problem.  Was there ever a solution? It's very annoying that I can't attach a file using the button in Outlook.

    This does not happen with other drop down menus.

    It worked correctly in safe mode.

    I disabled all add-ins and attach did not work.

    I disabled my virus software and attach did not work.

  • Steve, check this link

    http://answers.microsoft.com/thread/717b604f-3c31-4c4f-990e-50501e0e8b50

    9+ users are waiting for solution on that particular post. either they are using the quick access toolbar for adding attachment. but at this point can't attach any one drive or sharepoint attachments in the email. One of my client personally facing the same issue. I have troubleshooted the same and issue does not happen in safe mode. I have removed the Antivirus and disabled all the addins, through registry as well. I have booted the machine in safe mode and it did not help either. 

    I believe this one is bug and should be highlighted to senior team for fix. 

    If you could give us solution then it will be much appreciated. But its a complete new feature and troubleshooting steps are limited.

  • We are having the exact same issue. User on Windows 7 using Outlook 2016 standard, no add ons or other tweaks. Menu shows for about one second then disappears.
    Tuesday, October 27, 2015 3:51 PM
  • I am experiencing the same issue.  My current workaround is to log in to the web client and attach from there.  Seems to just be one of those "new software" bugs.  Here's to waiting for updates... again :D

  • I'm experiencing the same issue too. Outlook 2016 on Windows 8.1. If I'm lucky I'm able to move my mouse to the bottom of the drop-down menu and click on "Browse This PC..." But I've got to be quick about it. It exhibits the same behavior from the Message ribbon and from the Insert ribbon.

  • Having the same issue with a lot of users inside my organisation running Windows 7 and Office 2016.

    We have got round the issue at the moment by adding the attach file shortcut to the quick access toolbar - you will have to "pop out" new emails, but it is easier that drag and drop. 

    Hopefully they will fix this bug soon.

  • I have run into the same issue on a Win 7 laptop with Outlook 2016.  I believe the issue may be with the 'Recent Items' cache being corrupt, and no signs of where that could be located to delete.

    I have tested in Safe Mode, tried adding the 'Attach File' to a new group on the Ribbon, created new Outlook profile, reinstalled Office, and attempted to locate the registry keys that are mentioned in other posts to clear Outlook cache but those weren't found.

    I have yet to try recreating the Windows profile since it seems like such a big step to fix such a small bug.

  • Please add about 30,000 users to this list having this issue.

    I am working with a customer for a Windows 10/Office 365 deployment. We have a clean image of Windows 10 with Office 2016 loaded. There are no add-ins installed. As others have mentioned, starting in Safe Mode does solve the issue.

    This happens on all platforms (Desktop, Laptop, Surface Pro 3). No anti-virus or client management agents have been installed yet. There are a variety of mice in use.

    This could be a showstopper for the customer if we can't get this resolved. Adding a command to Browse this PC to the Quick Start Menu is not an acceptable workaround for my customer.

  • We are seeing the same thing. Windows 7 with Outlook 2016 and we cannot keep the attach file list from closing right away. New profile on the same machine for a different user and everything is fine but I did not try to open a file in another application.

    Repair did not work.

    Works fine in safe mode.

    Does not work in normal Outlook with all add-ins disabled.

    It acts like it is trying to update or go online. when I click the attach file and I have the volume up, I can hear numerous clicks like you were clicking on a link. Repeats about 5 times and continues after the attach file pop up goes away.

    I have recreated the Outlook profile to no avail. I really would rather not create a new windows profile but that seems to be the next available step. I just hope the issue does not return once the recent file list is populated again.

    The only thing that has worked for us:

    Click File

    Click Office Account

    Click Sign Out

    Click Yes

    Close Outlook

    Open Outlook - Sign in with Work account

    The user mentioned he tried to setup a one drive account with a personal username and password about the time this issue started. Hopefully the problem does not return.

  • Has this been resolved?  I am experiencing this with my clients as well and it is holding up deployment.  To me it seems like it is querying for Connected Services for items to display and if you do not have any services configured it never quits but it keeps refreshing the menu item in question.  I have noticed that the whole New Email window border flashes like something is refreshing it after clicking Attach File.  Something is very wrong with this!  I am hoping Microsoft does not require a connection to service for this to go away.  Also, I can't connect to any services under Office Account, keeps saying Can't Display Online Services,  Sorry, we had a server issue.....  Try Again.  Would this be related?

    Cheers,

  • Anyone ever get an answer to this?  I've looked in 20+ threads and can't find anything that I have not already done.  Is an update coming?  Same as others: Windows 7 with Office 365.
    Friday, December 18, 2015 11:21 PM
  • Is there a solution to this? This is horrible. I cannot seem to attach any file in any manner using Outlook 2016. This is such a fundamental necessity!!!! I cannot believe it doesn't work! I am using Windows 7. Terribly frustrating!
    Monday, December 28, 2015 5:29 PM
  • I'm adding to the growing complaints about this all over Microsoft's community and support sites.  This is a completely ridiculous bug:

    Started this AM: I CAN NOT attach files to Outlook 2016.

    Can't attach files using the ribbon button OR drag and drop into email.  

    Haven't tried to repair.


    However, let me add that Office 2016 -- all of the apps -- is the buggiest version of Office ever released. And I've been using Office since the Stone Age.


    Get it together, Microsoft.  I don't expect to be a beta tester.  Linda

  • I have the same problem, started today not being able to attach a file. (It's been a few days since I had to attach a file)

    You think you have attached the file but looking closely the file is not attached. At least there should be a warning message! Guess I should of stayed with an older version of Outlook.

    The file is a 9 MB file which I have attached previously (2015) many times.

  • I've been having a similar problem to some here, and it appears there are two things going on for folks - some have the 'rapidly-vanishing-attach-menu' problem, and some have the 'ignore-any-attempt-to-attach-file' problem. On Win8.1/Office16/365 I do not have the first one, but I do have the second one. Browsing for a file from the attach button, or drag-and-drop a file into the message (reply or new) does nothing - or appears to do nothing...

    That was till somebody pointed out a fix they'd been suggested: change the email format from plain text to html

    That fixed it for me. Since my default format for new messages was html I only saw this bug on replies to plain text messages.

    Also note, you need to 'pop out' the message to find that format-text menu option (wth?)

    Hope that's useful for some folks googling (or binging) a solution to this.

  • Here is a work around that resolves the issue… for a period of time.

    1. Close Outlook.
    2. Close and save all Word & Excel files.
    3. Open a blank document in Word.
    4. Go to, File – Account.
    5. Select, Sign out.
    6. Now select, Sign in.
      Note: If asked, select either your Work account or Microsoft account as appropriate.

    You can now open Outlook and attach files as normal.

    I can't take credit for this as I found I it on another forum, unfortunately I can't find it again so my apologies to the person who came up with this solution.

  • For me, if Im trying to send in plain text it appears the file did not attach, however when I switch to HTML, there it is.

    When I change back to plain text, again the attachment field disappears.  But it seems the attachment is in fact there.

    found advice to delete MicrosoftOffice16_Data credentials (3 of them) in user account in Control Panel.

    Worked for me, did not have to Sign out / Sign in in Outlook / Office Account.

  • This method work for me since we use network drives that are associated with 365. My only guess is that it is having issues verifying the network location and fails. Which is why logging out and back in resolves the issue for me.

  • Six months and still no solution to this problem. Microsoft just doesn't care, as long as they get paid monthly. I am being charged monthly, and I cannot use Outlook 2016. I first encountered this when they first launched Outlook 2016. Since no one had any solution then, I downgraded back to Outlook 2013. Now decided to try Outlook 2016 again, and THE PROBLEM IS STILL NOT SOLVED. MICROSOFT JUST DOESN'T CARE!!!!!

  • A fix we are using on user's computer is:

    On windows 7  open start

    Search for Credential manager 

    Look for "Generic credentials"

    remove all the Generic credentials by clicking the arrow and then click Remove from Vault

    (this are credentials outlook and lync store to just open the application without asking for password)

    Restart outlook if you have it open, It may ask for the username and password

    After this steps you should be able to see the Attach file menu with the recent files 

    Hope this help you

  • You can alternatively log out of your office 365 account from the Account window (click on your name in the right side of the title bar).  Sign out and then sign back in.  Fixed.  I just did it on someone's computer that had the same problem.  That's the first thing I did and it worked.

    Closed outlook, then reopened - typed in the password and was good to go, I can finally accept meetings and attach documents without wanting to throw my computer out the window

  • 

    We have been experiencing this issue a lot as well. The fix that I have been implementing until a "permanent" fix comes along is: 1) Have your finger on the "B" key 2) Click on the "Insert or Attach File", and 3) Immediately after you click, press the "B" key on your keyboard. This brings up the "browse" option to look for the file(s) that you wish to insert or attach.
