Exception type: Microsoft.Exchange.Data.Storage.AccountDisabledException
Exception message: Cannot open mailbox /o=mms/ou=exchange administrative group (fydibohf23spdlt)/cn=recipients/cn=John Smith.
This issue occurs if there is a delayed synchronization between Active Directory Domain Services and the Microsoft Exchange Information Store service. Such a delayed synchronization may occur when a disconnected mailbox was recently reconnected.
Generally, replication between Active Directory and the Information Store occurs hourly. However, in large environments or in environments under very heavy load, the time between replications may be significantly increased.
If you experience any of the following conditions, contact the Office 365 Support Team to create a Service Request so that the replication between Active Directory and the Information Store can be forced for the affected mailbox database.
