Folks,
For a customer, they have Exchange 2013 on premises environment. Their users can send/ receive emails through Outlook client and OWA with attachment up to 20 MB. While users who are trying to send emails with attachment through iPhone - they can't do that.
Please note while we tested it on Android devices, there were no issues. It is only happening on iPhone devices.
While i was searching for this solution - i found out this link: https://technet.microsoft.com/en-us/library/hh529949(v=exchg.150).aspx
Which says, we need to make change in Webconfig file - i would like to know, if anyone have done this or is there any better solution available for this.
Please suggest.
Thanks, Sheeraz
