Dear Community,<br />
<br />
We have Exchange 2013 on premises environment. 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.<br />
<br />
Please note while we tested it on Android devices, there were no issues. It is only happening on iPhone devices.<br />
<br />
While we were searching for this solution - we found out this link: <a href="https://technet.microsoft.com/en-us/library/hh529949(v=exchg.150).aspx" rel="ugc">https://technet.microsoft.com/en-us/library/hh529949(v=exchg.150).aspx</a><br />
<br />
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 issue. please suggest.
