  • There are some issues with updates.

    You can find more information here ( https://www.howto-outlook.com/news/attachments-blocked-after-applying-june-2017-updates.htm ) (I can't insert links yet :) )

    A workaround for Outlook 2013 is uninstalling the update KB3191938.

    There are also issues with other versions for Outlook.

  • Hi,

    Have you tried to install the fix mentioned in the link shared by StimsR above? The official article is as following:


    I noticed that the error message is slightly different from the one mentioned in the following official article. What's the exact build number of your Outlook client?

    Could you please have a check and compare the version of any affected Outlook clients and non-affected Outlook clients (if there is any)? We're trying to determine whether the issue was caused by the mentioned June security updates.

    Please feel free to post back with any findings, we will then take a further look.
