Office 365 Outlook with Exchange / Kerio Connect problem synchronization big mails

Copper Contributor

After some months I find problem with mails from my clients.

I have mails on my Kerio Connect server that I don't have in Outlook for Mac. All the mails have size bigger than 25 MB. This mails not synchronized between Outlook and Kerio Connect.


I have these mails in my iPhone an iPad , there is everything right.


Where is problem?

I think it was a Kerio/GFI response to a Microsoft problem. Ages ago they were getting reports of Outlook users crashing when dealing with messages over 25MB. In fact, I've had Microsoft people explicitly tell me, via the Feedback Chat Window, that this, indeed, is an issue. Not sure about the "New Outlook" but it's irrelevant at this point since it doesn't support on-premise Exchange, which is how Kerio looks to it.

So, they (Kerio/GFI) put a hard 25MB limit on messages.

There is a setting in mail server.cfg but it's not officially sanctioned so it may make things buggy. (
