Can't connect to a mailbox after it's re-enabled in Exchange Server
Original KB number: 3132711
After a user's mailbox is re-enabled in an Exchange Server 2016 or Exchange Server 2013 environment, the user can't access their mailbox by using one or more client protocols.
When a user account has the Exchange mailbox disabled, the following Exchange attributes aren't removed from the user object:
msExchAddressBookFlags
msExchBypassAudit
msExchPreviousRecipientTypeDetails
msExchProvisioningFlags
msExchRecipientSoftDeletedStatus
msExchUMDtmfMap
msExchWhenMailboxCreated
protocolSettings
Use the Set-CASMailbox
cmdlet to enable the client protocol that's required for the user to connect to their mailbox. For example, to enable Outlook Anywhere for the user, run the following cmdlet:
Set-CASMailbox Jim -MAPIBlockOutlookRpcHttp:$False
