I have an iphone with my exchange account set up with activesync and it works fine for sending and receiving email - except when I try to send emails about 10MB or larger. They just get stuck in the outbox and a message pops up saying "Cannot send mail""Your mailbox is full"I checked and my mailbox is currently 28% full.
I checked with our exchange admin and the message size limit on our server is 25MB, and I can send large messages up to that size to and from outlook on my desktop with no problems. I tried deleting and recreating the exchange account on my iphone but it made no difference. I tried sending large emails from my iphone using a gmail address and that works fine. I can even send the large email from the gmail account on my iphone to my exchange account and receive it in outlook on my desktop, but I cannot send email larger than 8-9 MB from Mail on my iPhone!
Does anyone have any idea where the problem might be?
iphone 5S, iOS8, Outlook 2013, Exchange 2013.
