The solution below worked for our organization:
In the props.conf file located in [SPLUNK_HOME]\etc\apps\TA-MS_O365_Reporting\default, comment out the following:
[ms:o365:reporting:messagetrace]
MAX_TIMESTAMP_LOOKAHEAD = 30
SHOULD_LINEMERGE = 0
*#TIME_FORMAT = %Y-%m-%dT%H:%M:%S%Z
TIME_PREFIX = "Received": "*
category = Splunk App Add-on Builder
pulldown_type = 1
Create a new props.conf in [SPLUNK_HOME]\etc\apps\TA-MS_O365_Reporting\local and add the following:
[ms:o365:reporting:messagetrace]
TZ = UTC
MAX_TIMESTAMP_LOOKAHEAD = 300
TIME_PREFIX = "Received":\s*"
Thanks! Hope this solution helps.
