Not only are most functions buggy, but they don’t even respond to bug reports. Terrible service, used it for my company with 13 employees - everyone only had Problems with this. Document preview doesn’t work for most files, mail attachments get lost when forwarding on app. Some files with special endings can’t even be sent. The search function is a nightmare, especially when using google mail as well - you literally can’t find anything. The hot keys for reply all in an email thread replies to the last email if the whole thread always, instead of replying all to the Mail you are looking at in the email thread. It’s a complete Desaster and I will switch my company Mails to a more reliable service.
