Before requesting a quota increase, please consider these steps.
- What is the business need in justifying the storage increase?
- Are you currently being warned about their storage quota or actually experiencing a send prohibition?
- Has any low-level auditing been done on mailbox content (including the sent items) to see what is taking up your current space?
- Has the age of stored e-mails been assessed? How much is over six months old? A year old? Three years old? Can some of this mail be archived or deleted?
- Have you retained electronic messages from their mailbox according to state and federal laws, making sure to remove personal and incidental communication (e.g. social networking e-mails from Facebook, MySpace, Twitter, other personal mail, mp3's, video files, etc.)
- Have you removed or moved large attachments from their production account to their SharePoint site or other file storage (local or networked)?
- What steps have you taken to clean your mailbox? Delete the trash, remove old transitory communication, archiving old messages, etc.?
