MSA log file contains different errors like "Error -2147221241" or "Error -2147467259"

MSA log file contains different errors, but before all the errors started to happen there is an entry in the log file which indicates a problem with memory settings:

HealthMonitor: TraceMsg 2703 The agent's system memory limit 64000 Kb has been exceeded. Agent will be terminated.


The log file also contains many errors like:

CStore::GetFolder Error -2147221241 The client operation failed. - MAPI_E_INVALID_ENTRYID (Microsoft Exchange Server Information Store) Low level error: 0x0 File: 'aeMAPIStore.cpp' Line: '370'

CMessage::CopyToPST Error -2147467259 An unexpected error has occurred (Subject:, SourceKey:)

To resolve this issue
- Stop the agent
- Increase memory limit for the agent to at least 256MB
- Start the agent again.

All errors should disappear from the log and MSA should be able to proceed.
