TB often decides to re-sync (re-downloads the message headers) whole whole o365 imaps account and while doing so, it DOES NOT check an Inbox folder (only when restarted whole TB - and then it doesn't apply filters) .. I can see many new messages getting piled in Inbox via web mail but TB doesn't check/see them because it is re-downloading inanely other folders with hundreds thousands emails in which resource costly operation and lengthy also. This renders TB absolutely unusable, good only for consuming a bandwidth and data (on mobile broadband). Is there any way to force TB to check periodically an Inbox folder while resyncing other folders (and yes, it's redundant and buggy - should not resync them at all so often) like it does on whole app restart only once ? Hitting button Get Mails or whatever else doesn't help. TB is jut not checking Inbox at all and also it seems it's ignoring mail server notifications about new messages. regards, d
