Hi guys,

Im experiencing a problem with my created rule in mailflow of exchange 2013, i set that any email with .zip, *.zip extension will be block if someone attempt to send an email with these kind of attachments but nothing happens. I tried to set the date when it will be activated to testvbut still emails with .zip attachments are received and can be downloaded. Please advise.

Hi

What CU levels currently do you have ?

Hi 

I saw it already please see attached screenshot



Hi,

I recommend you use the following cmdlet to verify the attachment filter entries that filter file names with a .zip extension.

Get-AttachmentFilterEntry FileName:*.zip

What's more, run the following cmdlet to check the blocked file types.

Get-OwaMailboxPolicy | fl BlockedFileTypes, *attachment*

Hope this can be helpful to you.

Hi ,

Based on my knowledge ,You can enable the transport pipeline logs to find out whether transport rule agent on the pipeline is acting upon those messages or not .

Though the link for exchange 2010 but it supports exchange 2013 too.

Hi,

I already resolved this issue by using Exchange shell command 

New-TransportRule -name 'Block All .ZIP Attachments' -Priority '0' -Enabled $true -AttachmentMatchesPatterns '.zip' -DeleteMessage $true

And I edit it using ecp to send a message to those wo are trying to send an attachment with .zip file.

Thank you guys for helping. all of you give me a good answers.
