Outlook 2016 exchange inbox repeatedly updating
When the Directory Server (LDAP) information is configured correctly in the account settings, the functionality is enabled for directory lookups, but Outlook will repeatedly display an error code 17768.
We have contacted Microsoft about this and unfortunately they do not have any working solution.
Note: starting with Outlook v.14.3.5, server-side rules are supported for Exchange Server 2010 SP1 and higher.
Categories assigned to shared items are only for the benefit of the user who assigns them If a user assigns a category to a shared item in a public folder or in a shared folder they will only be viewable on that one machine.
Categories assigned to shared items do not sync to the Exchange server and will not be available for the same account on other computers nor will they be available to other users.
If a user sets permission levels only to allow free/busy or free/busy limited details, an Outlook 2011 user will not be able to see any details of the shared calendar.
PC users must grant "full details" to the Outlook 2011 user.
