Hi, When mail gets stuck it is a good idea to know where it is getting stuck. Is it at the SMTP receiving stage, or on route to the mailbox from what used to be known as the hub transport components but is now a set of common components? I have seen mail stop with AV products at both stages, and also a single message causing the AV to chuck the message out but in a way as to not remove it from the queue, and n which case removing that single message was enough to clear the whole queue. Not a huge help I know but a lot of people don't install AV checking tools on the Exchange server these days, relying on an upstream appliance or service to do mail cleaning instead. This releaves the Exchange server from aving to deal with processing bad mail and also gets rid of the email before it even gets to the stage of the Exchange boxes. Andrew. ________________________________________ From: George Bell [george@techno-vision.co.uk] Sent: 06 November 2018 13:17 To: Blind sysadmins list Subject: [Blind-sysadmins] Exchange Server 2016 and ESET Do any of you have Exchange Server 2016 running ESET anti-virus software for Exchange? Access to e-mail with Outlook simply stopped around noon yesterday for no apparent reason. Having spent last night and into the early hours of this morning on to MS Technical Support (in Bombay), as a last move, they advised the removal of ESET which, I hasten to add I was extremely reluctant to do. The removal process took an abnormally long time, but after a re-boot, all was back working again. (Apart from a ton of mail that would otherwise have been stopped!) Has anyone experienced similar? MS seemed quite confident, as if we were not the first to have such an issue. ESET themselves are baffled, but with their support, we will be trying a re-install later today.
