I can’t view/download certain attachments

Error message:

Access to attachments has been blocked. Blocked attachments: <FileName>

 

Answer:

Direct file access lets users open files that are attached to e-mail messages and files that are stored in Windows file shares. WorldPosta Security team manages direct file access to maximums client’s data security.

The following table lists the file name extensions and MIME (Multipurpose Internet Mail Extensions) types that, by default, are set to Allow, Block, or Force Save:

– Allow File and MIME types in the Allow list can be opened from Outlook Web App if the
application that’s needed to open the files is installed on the client computer. Allow overrides
Block and Force Save.

– Block File and MIME types in the Block list can’t be opened. Block overrides Force Save and is
overridden by Allow.

– Force Save File and MIME types in the Force Save list must be saved to the client computer
before they can be opened. Force Save is overridden by Allow and Block.
