always syncing

Hi there… doesn’t look like anyone takes any notice of this forum, but basically I haven’t had any majopr problems with emClient until recently (the last few months)… it just won’t let me send any emails with large attachments… even as little as 744KB - it just keeps syncing out before it sends, even after I’ve set all the options to Never Sync, the sending message bar gets 3/4 of the way there, and then the Last Synced message comes up, leaving the message in my outbox. Seriously disappointed…

the Synchronization setting is only relevant for POP accounts, as other mail protocols Synchronize all your data by default.
What version of eM Client are you currently using? Check for the full number in Help>About section, please.
What mail account does this issue happen with? What mail protocol does it use?
