When setting the sorting rule in Outlook, AND / OR combination can not be done well if it is the usual setting. I will introduce the recommended settings especially when you want to use the OR condition.
Use header information for mail sorting
In the usual sorting rule, relations between items are AND. Therefore, you can not set
sender as X, or 'Y' in subject line in normal rules.
Therefore, use the header information of the sorting rule.
AND/OR combination sorting in Outlook
Normally, it will add the filtering target to each index such as sender as follows. In this case, the OR condition is in the index, but the relationship between indexes becomes AND.
Since it is normally not possible to use the OR condition between indexes, use in the message header here.
By adding mail address or subject (subject character string) here, it is sorted according to the OR condition.
By doing this, conditions like those that had to create two rules under normal circumstances can be summarized as one.
Conclusion - Combine AND/OR conditions with Outlook’s sorting rules
By using message header information as mail sorting condition in Outlook, it is possible to create filtering rule corresponding to OR condition between items.
