Morning Linc
I appreciate your patience!
OK
I carried out the Guest and Safe Mode tests
Set up Guest Mode as instructed
Sent test email to it and the unread marker showed for a while but eventually (maybe 5 mins) disappeared
All my old mail came into the account which was read and unread but no markers showed for the unread items
I then checked my iPhone which was showing unread markers but as soon as I started using that the unread markers disappeared
Safe mode test was around the same result - trial mails showed the unread marker for a while but when left for a short time they cleared down.
???
I said yesterday should I delete my main account and re renter it - to test this idea I created a new IMAP account and loaded that onto the Mac in my normal log in mode - I did that yesterday and the test mail that I sent to it still show the unread marker even with all the trials I have conducted which leads me to want to try deleting my main account and re entering however I cannot find "delete account" in any menu I can find the "de activate" check are but not delete?
Await your kind thoughts
Regards
Dick
