Problem: While archive email from a Microsoft Exchange server an EWS error with error code ErrorVirusDetected occurs.

Solution: An Exchange integrated anti-virus software prevents the delivery of the requested message to MailStore. Therefore the email could not be archived successfully. Due to false-positives of anti-virus programs, it is advised to manually review the corresponding message before deleting it from the mailbox.

Due to that error the archiving profile itself terminates with a non-successful status code. This behavior can be changed since MailStore Server 8.1 by modifying the global property public.arcclient.skipVirusDetected by executing the following command in MailStore's Management Shell:

store-setprop --name="public.arcclient.skipVirusDetected" --value="true"

Please note: Independent of this global property, MailStore Server is neither able to archive messages where the above error occurred nor delete them from the Exchange server.
