Users can't access their archive mailbox in Outlook in Exchange Server 2016 or Exchange Server 2013 Cumulative Update 10
Consider the following scenario:
- The MAPI/HTTP protocol is disabled in a Microsoft Exchange Server 2016 or Exchange Server 2013 organization.
- The MAPI/HTTP protocol is enabled at the mailbox level for one or more users.
Note The issue may occur even after the MAPI/HTTP protocol is enabled for the organization.
This issue occurs because Exchange Server returns RPC/HTTP information for a MAPI/HTTP autodiscover request when the MAPI/HTTP protocol is disabled in the Exchange organization.
To work around this issue, use one or more of the following methods.
Method 1Use Microsoft Outlook Web App or Microsoft Outlook on the web instead of using Outlook.
Method 2Disable the MAPI/HTTP protocol for the affected users by running the Set-CASMailbox cmdlet as follows:
Set-CASMailbox <Alias> -MapiHttpEnabled $False
Method 3Enable the MAPI/HTTP protocol for the organization by running the Set-OrganizationConfig cmdlet as follows:
Set-OrganizationConfig -MapiHttpEnabled $True
