Unable to view some email attachments

By snide3 ·
I am running Windows 2000 environment on three servers DC1, DC2 and EX1 (Exchange 2000) and the email client is Outlook 2000. My users are complaining about not being able to view certain attachments. I looked under the help on Outlook and it explains that these files are being blocked under a level 1 security. It goes on further to say that if you use Microsoft Exchange Server, your administrator can add and remove file types for both levels of e-mail security.

My question is how and where do I do this in Exchange 2000? I just recently migrated from Exchange 5.5 to 2000, still learning the in and outs of Exchange 2000.

Thanks in advance for your help.

This is nothing to do with Exchange but everything to do with the new security features in Outlook to prevent spread of viruses using program extensions.
I suggest ZIPing or renaming files up before sending certain attachments, most data and Office files will send ok (except MDB files). Its program files such as EXEs, COMs, PIFs, SCRs, VBSs that can be a threat.

You can allow certain types of files through with registry settings on the client PCs to reduce the security level for certain attachments.;en-us;829982

Your users should also be able to save the attachments to disk, then view them using the apprpriate program - this takes Outlook out of the equation so it cannot 'interfere' with the viewing process.

Also, are you sure it is attachments they cannot view, and not the contents of the mail messages themselves? I say this because Outlook can be configured not to allow 'external' images - unfortunately this includes not only images which need to be downloaded from external websites but also images which are part of the message.

Good luck
