Global address book not updating when accounts are disabled
The cached mailbox and OAB are updated periodically from the Exchange Server computer.
The user can select Cached Exchange Mode or Online Mode during account setup or by changing the account settings.
I've updated other systems with Office 2016 and 365 accounts but this is the first time I've seen this problem.The offline address book contains the properties of a user, such as email addresses, that Microsoft Outlook requires to send an email message and display information about the sender.By using an offline address book, Outlook doesn’t have to connect to Microsoft Exchange Server to resolve names or open the records for each user.Note: If you are using Cached Exchange Mode, we recommend that you download the full details of the offline address book.This reduces the number of times the Outlook window might become unresponsive and the number unnecessary connections to the Microsoft Windows Server Active Directory.
