Several customers running GW2012 SP2 are finding that from time to time Outlook 2013 address book appears in users Mail Profile
at this point emailing from within other software ie. Sage 50 in most cases stops working correctly
specifically - Sage 50 allows email of Invoices to be sent via PDF email

There are TWO modes
(1) Send immediately - this still works
(2) Send emails to be approved - ie. emails in the mailbox which is then sent after checking > resend

This happens apparently at random but fairly frequently ie. every 3-4 weeks!!
(at this point as I mentioned Outlook address book is now in the User profile)

Automatic updates are disabled in both Windows 7 & Office

Customers are using MS Office Home & Business - NOt installing Outlook 2013 or removing Outlook is NOT an option with MS Office Home and Business
