365 ATP scanning time
I know the time it takes to scan will vary but does it matter if the user keeps the email open that contains the attachment that's being scanned vs closing the email and checking back in 5 minutes or...
I find most of the time 2-5 minutes and the attachment is available.
I ended up turning off the setting that delivered the email without the attachment due to complaints from users they couldn't open it. It seemed like a good idea when I set it up but the users got frustrated.
Now the email gets delivered once the attachment has been scanned and the only time they notice the delay is with emails from the copier which no longer arrive instantly.
For your second question, try a mail flow rule which sets the message header to X-MS-Exchange-Organization-SkipSafeAttachmentProcessing and the value to 1 and set it to apply under specific conditions such as sender domain.
I came across the "X-MS-Exchange-Organization-SkipSafeAttachmentProcessing" workaround while I was searching but someone said it doesn't work anymore. I guess I'll need to test it out.
Appreciate the tip
