outlookIf you’re running Microsoft Outlook you may have run into this error message. The Microsoft KB article says you can run into it when trying to send an email from a third party app. I’ve also read where Adobe Acrobat can cause it. For me, I’m running Windows 10 Technical Preview and Office 365. The “Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client.” error message would just randomly popup for me, even without trying to send an email.

There’s a Microsoft FixIt app you can use, but it doesn’t work if you’re running Windows 10 Technical Preview. Instead, you have to edit the registry, then run Office Repair:

– Click Start, and then click Run.
– In the Open box, type regedit, and then press ENTER.
– In Registry Editor, locate the following subkey in the registry:
HKEY_LOCAL_MACHINESoftwareClientsMailMicrosoft Outlook
– Select the subkey, and then press DELETE.
– Click Yes.
– Quit Registry Editor.
– Start Outlook.
– For Outlook 2000 and Outlook 2002, click the Help menu, and then click Detect and Repair .
– For Outlook 2007, click the Help menu, and then click Office Diagnostics .
– For Office 2010, Click Start, click Control Panel, click Programs and Features, select Microsoft Office 2010 and then click the Change button. Next, click Repair, and then click Continue.
– Follow the instructions on the screen to complete the repair.

    Thank you! Running Office Repair set Microsoft Outlook as my default mail client. I no longer get the error message!

    When I right click and choose to send by email I get that message. Two MSFT techies in two call over 3 hours could not fix it. Please provide fix for Office Professional Pro 2016. Repairs and re-install of pgm did not work and I don’t want to delete in registry until you say to do it. Thank you.

      Unfortunately reinstalling the programs don’t always clear out registry keys. If you’re comfortable enough, follow the steps I have listed above to delete that registry key. Just triple check yourself that you’re deleting the correct registry key.

    I deleted
    HKEY_LOCAL_MACHINE\Software\Clients\Mail\Microsoft Outlook

    and ran both the quick and internet repair on my Office Professional Pro 2016

    No luck. Any other thoughts?

    Running Office 2016, also tried this fix including deletion of Registry Keys – no fix.

    This worked until the past few days.

    I don’t know why but I don’t get the error message anymore. Go Figure.

    To everyone still having the problem:

    Outlook has a permissions problem for some reason.

    Non-admin users do not have the right to read the contents of the registry key: “HKCR\Installer\Components\F1291BD604B860441AB89E60BDEE0F9C

    Once I added reading rights to all authenticated users for this key, the error disappeared!

    Thanks again for the quick replies and help from Melon Chen from the TechNet Community Support.

    Kind regards,

    Magnus Kramer

    The user is a local admin for the computer so he has rights to the registry key but yet he still have the issue.

    I’m not even using Outlook, just gmail online, and I get this message at random times. Usually when I’m not doing ANY email. I’m not comfortable doing that fix above. Can I just ignore it?

    This worked for me. Even “System” had no read-right.
