The basic thing you can do is flag mail (sometimes called follow-up) as it comes in and then a smart filter that looks for flagged mail. Only remove the flag when it has been fully actioned. In OWA you use rules to add categories (coloured flags), likewise in Mac mail.
I'm pretty sure the Mac mail flags were visible in different Macs using the same home IMAP account.
I think @fredbert is onto something here. What about forwarding email based on rules. Not sure if this is possible with the usual clients (maybe a mail app)
When an email arrives from such and such, forward a copy to the Mrs for example.
Is that possible?
I briefly setup a forward based on a rule to test. It would accomplish the objective for some, but not all cases. When an email comes in subject ‘statement from landscaper’ it’s then forwarded to her. Potential problem with this is the numerous forwards with attachments filled up the sent folder with attachment used storage space.
You actually are probably correct on this. I setup the forward address yesterday. Next is to create a test filter and send from another email account. I think I’m now vaguely recalling that there IS NOT a sent copy kept.
