Exchange problems in Mail
i have been using mail to connect to my corportate exchange for years both at the office and at home. Starting in July it stopped working properly. shows connection errors.
it works fine from Outlook for Mac using same credentials and the same credentials work fine logging into icloud from the browser.
I have deleted the accounts and recreated with same failures?
Could not connect to this exchange server
GMAIL works ok as well.
