Late last week I started having users no longer receiving emails. No changes have been made on our Meraki set up nor on our exchange server. When deleting the accounts to re-add to device the following message comes up:
"The connection to your mail server is timed out. Please check your mail settings."
Again no changes have been made to Meraki or the exchange server. This only effects Outlook, Gmail & Samsung's email app are unaffected.
