I installed my own instance of OnlyOffice Workspace and I enabled and configured the email client with my email IMAP / SMTP server to send / receive emails.
We can ignore for the moment that the email module lack of OpenPGP encrypted email and related keys (in 2023??) - Ok corporate email should cross the web unencrypted to the benefit of Mr. Big Data!
What leave me stunned is that the shown content by OnlyOffice of email inbox is completely out of sync with the actual and real content of inbox as shown by any email client, here including RoundCube! OnlyOffice shows also email erased days ago from my inbox by other clients, so I have to do double work removing them also on the OnlyOffice email client!
So, the questions: Is there any switch or trick to have the actual mailbox content reflected also on OnlyOffice or I have to see also email removed days ago?
If there is no hope to have OnlyOffice mail working as any modern email client, is there any hope to integrate RoundCube into OnlyOffice?
