Mail not syncing with Microsoft Exchange account
I have two Apple computers (both on iCloud) and Mail (v12.4) on both recently stopped syncing properly with my workplace Exchange account (which I've used for years with no major problems). They only rarely download new mail (it can take days). There is no problem sending mail, except I sometimes get a sequence of pop-up message boxes saying "draft cannot be saved" (four that all have to be dismissed before I can do anything else). Rebooting does not help, nor did deleting and recreating the email account from scratch which I tried on both machines. Other mail clients (Spark) work fine (except I don't like them as much!). Any ideas appreciated.
