LOL We had a couple of issues with people sending out large attachments and clogging up the transport queues, and that’s when I discovered that someone had set our message limit pretty high. So I did some investigating and found that Microsoft had set their limit on Exchange Online to 25 Megs. Considering we were planning to move to O365 Exchange Online, I dropped our limit down to 25 Megs, and we haven’t had much trouble since. This goes right back to “just because you can, doesn’t mean you should.” However, while you’re at it, will you please try to send an email with a 1 TB attachment and let us know how long it takes? We’re all curious. ☺

If so, is it still true that large attachments cause performance problems? From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Michael B. Smith Sent: Sunday, December 07, 2014 7:31 PM To: [email protected]<mailto:[email protected]> Subject: [Exchange] RE: Attachment Size Redux You have a good memory. I wrote an article about that for a magazine that discussed the Exchange 2003 transport service. It doesn’t apply to modern (64-bit) versions of Exchange. From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Mayo, Bill Sent: Friday, December 5, 2014 12:44 PM To: [email protected]<mailto:[email protected]> Subject: [Exchange] Attachment Size Redux I know this topic has come up before, but I am running into a discussion about it again. I am almost certain that Michael B. Smith had a particularly informational post about this sometime back, but I cannot find it (swore I saved it, but can’t find it—also searched the current archives unsuccessfully). It is my recollection that it explained how it delayed delivery of other mail, but most importantly, that there was some maximum over which Microsoft would not support it. Did I dream all that, because I can’t seem to find this documented anywhere? I would greatly appreciate it if anyone someone has that info, whether in my recalled format or elsewhere. I would also appreciate any other links or individual information anyone has on the topic of how big is too big for email attachments. I have all the old “straw poll” messages, so I know what people are/were using as the limit, I am looking more for documentation of the potential issues caused by allowing larger attachments.
