Using X-Priority Headers
What is an X-Priority?
The X-Priority is used to indicate the importance of a message. Microsoft supports 5 X-Priority levels https://docs.microsoft.com/en-us/openspecs/exchange_server_protocols/ms-oxcmail/2bb19f1b-b35e-4966-b1cb-1afd044e83ab with 1 being the highest and 5 the lowest.
When enabled through Profile > Issue > Use Mail X-Priority Priority, JEMH will map this to an actual Priority defined in the Project Priority Scheme.
How JEMH works with X-Priority header
Since 3.3.111 & 4.0.4
Starting in the above versions, JEMH will make use of the priorities set on a per project basis through a Priority Scheme. As the number of Project Priorities can be any number, the 5 X-Priorities map into the set of available Jira priorities. We have ensured that an X-Priority value of 1 always maps to the highest Jira priority and 5 always maps to the lowest Jira priority. Values 2-4 will spread between the highest and lowest priority depending on how many there are. If the value supplied has been deliberately set above 1-5, it will be tested for an exact match on a Jira priority ID, non-matches are treated as lowest priority.
How X-Priority values map to Jira priorities
The tables below show how X-Priority values map to project priorities. The selected index indicates the target priority from the available project priorities (1 = first/highest).
