Outlook 2010 Attachment security warning

    Question

  • How do I disable the stupid attachment security warning please?

    Outlook started to block all attachments for a single user. xls doc pdf ppt  even zip 
    I added the file extensions to the reg under the Level1remove and created the level2 also. 

    not much luck.  but some do now show but when we click on them the Attachment security warning will appear asking to save to a location but wont allow to save?  so whats the point in it? 

    I'm guessing that a microsoft update has caused the issue maybe as 2 more users are now having the same problem. 

    Can anyone help?

  • If this is the same issue I have (Win7, Outlook 2010) then I get a pop-up labeled "Attachment Security Warning". The text within the box says:

    "WARNING!

    This file me contain a virus that can be harmful to your computer. You must save this file to disk before it can be opened. It is important to be very certain that this file is safe before you open it.

    Filename:   My_file.pdf

    Type: Adobe Acrobat Document"

    I then have to buttons, "Save to Disk..." and "Cancel". This did not happen  on my XP machine with Office2007. How do I make the attachment just open without having to save it?

  • What if any integrated Outlook A/V add-in do you have installed? (With a valid current system level A/V program installed - there is no need for any integrated Outlook addin)

  • SEP11 is installed but I do not think that it is integrated with Outlook 2010. Is there a way to check?

    Further searching of multiple forums seem to all end with "Nope, Tried all that, no joy". :-(

  • That is precisely the error message. I have already attempted the fix suggested with no luck. There is even a 3rd party GUI that can accommodate adding extensions (http://www.howto-outlook.com/faq/blockedattachments.htm).  Here is the list of files from my Level1Remove (most added by the mentioned app but PDF had to be done manually)

    Name: Level1Remove

    Type: REG_SZ

    Data: .ade;.adp;.app;.asp;.bas;.bat;.cer;.chm;.cmd;.cnt;.com;.cpl;.crt;.csh;.der;.exe;.fxp;.gadget;.grp;.hlp;.hpj;.hta;.inf;.ins;.isp;.its;.jar;.js;.jse;.ksh;.lnk;.mad;.maf;.mag;.mam;.maq;.mar;.mas;.mat;.mau;.mav;.maw;.mcf;.mda;.mdb;.mde;.mdt;.mdw;.mdz;.msc;.msh;.msh1;.msh2;.mshxml;.msh1xml;.msh2xml;.msi;.msp;.mst;.ops;.osd;.pcd;.pif;.pl;.plg;.prf;.prg;.ps1;.ps1xml;.ps2;.ps2xml;.psc1;.psc2;.pst;.reg;.scf;.scr;.sct;.shb;.shs;.tmp;.url;.vb;.vbe;.vbp;.vbs;.vsmacros;.vsw;.ws;.wsc;.wsf;.wsh;.xbap;.xnk;.pdf;.doc;.docx;.msg
