Mail showing wrong number of incoming emails
Hi
Does anyone have any idea why, since installing Mavericks, my Mail often shows the wrong number of emails arriving in my inbox? For example it might show 18 incoming messages, when in fact only four arrive in my inbox. There are no Junk messages appearing.
Occasionally it also shows a wrong (larger) number for outgoing too.
Any advice gratefully received!
iMac, OS X Mavericks (10.9)
