Upload files to a specific site	Sites.Selected	Application	Gives access to only sites you want the application to write to (Required an additional Step listed below)
Delete files on that specific site	Sites.Selected	Application	Deleting Files from Sharepoint from the iMIS interface.
Create / manage email category definitions	MailboxSettings.ReadWrite	Application	Used for Assigning and Creating categories. (Only Required if using Categories)
Assign a category to a specific email	Mail.ReadWrite	Application	Required to modify the categories property on a message
Read email (Subject, Body, To, From, CC, Attachments, mailbox owner)	Mail.ReadWrite	Application	Mail.Read alone would suffice in isolation, but is redundant once Mail.ReadWrite is already required above.
