Cannot Sync Gmail Account

I have read previous forum posts and have configured gmail as POP and as IMAP. Neither of them have been successful.
I love eM Client, but if this issue cannot be resolved, I will not purchase a full license

it is very strange. Gmail accounts are usually set automatically and work without any problems. How did you create the account? Are you getting any error messages?

No. In fact both IMAP and POP show as being functional in the diagnostics tab. However, I cannot send or receive email. Mail sits in my outbox permanently.

Actually, neither POP or IMAP are used for sending messages so I recommend you to check SMTP settings and try to Diagnose/Fix it in the DIagnostics tab. If it will not help, send us your logs please - then we will be able to advise you further.
