Exchange Mailbox Assistants service crashes and triggers event 4999 in Exchange Server 2013

The Microsoft Exchange Mailbox Assistants service (MSExchangeMailboxAssistants) crashes repeatedly at intervals of several minutes in an Exchange Server 2013 environment. This crash behavior affects activities such as Offline Address Book (OAB) generation and public folder hierarchy synchronization.

Additionally, the following 4999 event is logged in the Application log during the intervals:

Note To determine whether you're experiencing this issue, verify that both of the following strings appear in the event data:
  • MSExchangeMailboxAssistants, M.Exchange.Assistants, M.E.A.TimeBasedAssistantController.UpdateWorkCycle, System.ArgumentOutOfRangeException
  • exMessage=Time-out interval must be less than 2^32-2.Parameter name: dueTime
Note These symptoms may be caused by an administrator or by third-party applications (such as Odin or Parallels, which are used for hosted Exchange Server 2013 deployments). However, these symptoms don't occur in Exchange Server 2016 because the value of the OABGeneratorWorkCycleCheckpoint property can't be changed on an Exchange Server 2016 server.
This issue occurs because the OABGeneratorWorkCycleCheckpoint property is set to a value that's greater than 49 on an Exchange Server 2013 mailbox server.
To work around this issue, run the following cmdlet to change the value of the OABGeneratorWorkCycleCheckpoint property to a value that's less than or equal to 49 days:
set-mailboxserver -OABGeneratorWorkCycleCheckpoint <value> -identity <servername>

Note The default value of the property is 1 day, and the string of the property resembles the following:

OABGeneratorWorkCycleCheckpoint : 01.00:00:00
