I have Exchange 2013 and some of the users could't use Mobile Device and Outlook web app but the others can.
O checked the properties of the User Mail box and OWA and Actyve Sync is enabled.
they could't use it but they were able to use it in the past.
is it related to DB?
Should I migrate the User Mailbox DB?
or ii's related to IIS and it's virtual directors?
