Some of my users are having issues sending emails with attachments from iOS devices but the same works fein from desktop versions. There seems to be a link to the size of the attachment, as an example 8mb files are causing an issue where 1mb files are fine.
I have checked maxRequestLengths in config files and they look to be well over the 8mb size. I'm just looking for a little guidance to point me in the right direction.
Any help is much appreciated.
Environment is Exchange 2013 SP1 running on Windows Server 2012 R2.
