Do not use occasion as a verb when a simpler word such as cause would do as well. It is a stilted verb.
Any inconvenience occasioned is regretted.
I am sorry for any inconvenience occasioned to you by this inadvertency.
The word seems to be treated in official letters as the natural partner of inconvenience, and it is always a bad sign when one word invariably suggests another. (Alternative accommodation, real danger and active consideration are examples.) There are plenty of other verbs with much the same meaning, and they should be given their innings. "Any inconvenience you have suffered." "Any inconvenience you may have been caused." "Any inconvenience you have been put to." Any of these will do for a change.
The person to whom the inconvenience is " occasioned " need not always be described as "experiencing" it.
