Question
If I delete users, will my storage usage decrease?
Answer
If you delete users, those users will be removed from your ticket metadata and will marginally decrease the amount of data stored in your instance.
Each user is counted as 0.05 KB of data, which means deleting users may only minimally decrease your overall storage.
To reduce usage effectively, use ticket deletion instead.
Tip: If you have the Advanced Data Privacy and Protection add-on, you can define ticket deletion schedules to automatically delete specific types of tickets in your account. For more information, see the article: Creating multiple ticket deletion schedules (ADPP add-on).
