Fix Advanced Threat Protection Attachment Scan When Email Is Auto-Forwarded
Currently ATP fails to release an attachment (continually displays ATP Scan in Progress in place of actual attachment) when the email with the "stuck" attachment has been auto-forwarded by a user with an Out-of-Office rule in place within the same email domain. Strangely, the email attachment is scanned just fine from the auto-forwarding recipient and can be manually forwarded to any recipient, but if it's auto-forwarded, the attachment stays stuck in an never displays as available. This has been reported to MS Support who attempted a work-around (which failed) Office 365 Ticket #30126-5487056 .
Same issue here, I am autoforwarding mails to one mailbox to overcome the missing "combined inbox" feature in Outlook 365.
This worked fine and all mails come to one mailbox.
Now our company has implemented ATP 50% of mails with attachments end up with ATP Scan in progress annex, that shows just a picture of the file being scanned, but if you click that it will open in Office 365 online, without ever giving the option to save it, nor does the file become available afterwards.

Same issue in 2020, any resolution?
Still continuing. When u can fix this issue?
still happening . . . extremely frustrating
This is totally unacceptable to wait hours for attachments to be scanned, It has been going on for a while now and the clients are very frustrated.
Still happening in June of 2019!

Years later and this is still an issue...
I am running into this issue as well... Any update as to a fix? This is happening to me on mail being forwarded from one Office 365 to another via mail flow rules in Office 365.

Workaround: Anytime an atp appears stuck (more than 5-10 minutes scanning), forward a copy of the message to yourself and the attachments will magically appear

I am having this issue as well. But it is happening randomly to my users. No auto fardward was used. End user received email that was manually forwarded by sender.
facing the same issue, anybody got the solution or make this work?
This problem it happens to me with one user of outlook. Some body has been found a solution?

I am also looking for a solution to this problem.
Anything new on this?
This is should be fixed soon. Delay the delivery of forwarted messages rule could be the workaround for this now, but hoppefully this can be fix soon.
Has anyone found a way around this issue? The only solution we have come up with short of disabling ATP and dynamic delivery, is to have the user who will be out of office delegate their mailbox instead of auto-forwarding it when OOO.
