Some file types are blocked
There are a number of reasons why you may see the "This message was blocked because its content presents a potential security issue" error in Gmail. Gmail blocks messages that may spread viruses, like messages that include executable files or certain links.
Why messages get blocked
To protect you against potential viruses and harmful software, Gmail doesn't allow you to attach certain types of files, including:
- Certain file types (listed below), including their compressed form (like .gz or .bz2 files) or when found within archives (like .zip or .tgz files)
- Documents with malicious macros
- Archives whose listed file content is password protected
- Password protected archives whose content is an archive
Note: If you try to attach a document that is too large, your message won't send. Learn more about attachments and file size limits.
File types you can't include as attachments
.ADE, .ADP, .BAT, .CHM, .CMD, .COM, .CPL, .EXE, .HTA, .INS, .ISP, .JAR, .JS (NEW), .JSE, .LIB, .LNK, .MDE, .MSC, .MSI, .MSP, .MST, .NSH .PIF, .SCR, .SCT, .SHB, .SYS, .VB, .VBE, .VBS, .VXD, .WSC, .WSF, .WSH
What you can do
If you're sure the file is safe, you can ask the sender to upload the file to Google Drive, then send it as a Drive attachment.
