iOS 7 and sending emails larger than 40KB from Exchange accounts
Posted on 2013-11-19
The Server enviroment is SBS 2008,
Exchange 2007, IIS 7. My end users with the latest iphone IOS 7 are intermittenly having issues sending or forwarding emails. The message they see implies that the message is to large. This can occur even with a txt only message, (no attachments)
I've seen apple forums pointing at the exchange server as the problem, stating that the
setting in IIS for UploadReadAheadSize setting should be increased.
I'm not having this issue with any Android devices or Apple devices before IOS 7.. Has anyone else seen this and found a solution to this ?
