Email Growth Mitigation Techniques

Email Growth Mitigation Techniques

 Check out this presentation with screen shots and step by step guides on how to manage your email at UBC (Fall 2022)

Checking size:

Size of your mailbox can be checked by the user from within Outlook by choosing File à Tools à Mailbox Cleanup à View Mailbox Size. There will be a Server Data tab that shows all used data currently used by your mailbox. If you have an archive attached to your Outlook application, you will also see a Local Data tab that shows the space of your server data as well as your local data currently used by your email account within Outlook.

You can also ask a service desk technician to look at your account for a less granular look at the size of your mailbox.

Stripping attachments:

Stripping the attachments from emails is the best way to ensure your mailbox stays under control and within its space limits. Saving all attachments to a network location (OneDrive, K:\, H:\, P:\) will allow for the review of the attachments for future reference as well as give the ability to send a link to the document vs. sending a copy of it to a recipient.

  • OneDrive will allow for internally and externally accessible links to be sent to recipients instead of a redundant copy of the file.
  • UBCO networked drives (K:\, H:\, P:\) allow for internal linking for users who are permitted access to the storage location. This becomes optimal when multiple people of the same dept need to review a document. The file can be saved in the K drive to a common location and a link can be sent via Chat, email, or reference document.

Archiving is an option, but not the recommended approach for a few reasons:

    • Storage is a cost, whether it is on the exchange server or shared storage (k drive or OneDrive)
    • Creating large email archives could impact storage performance and/or result in corrupted files
    • Any stored files/email are subject to FOIPPA so could pose a risk to the university

Therefore, the recommendation is to manage your email storage by removing attachments and storing them elsewhere (OneDrive, Teams or shared network drives) as you receive them instead of waiting until you’ve reached the limit.

Archive emails to your computer first and then upload it to your preferred server (OneDrive or K drive etc) instead of storing everything directly on the server right away. This will decrease risks of performance issues and file corruption.

Macs should not be used for archiving as the file created can only be used on another Mac. Windows archives can be used on Mac or PC.

How to use Rules:

Windows Instructions

Rules allow you to move, flag, and respond to email messages automatically. You can also use rules to play sounds, move messages to folders, or display new item alerts.

The easiest and most common rule to create is one that allows you to move an item from a certain sender or with certain words in the subject line to another folder. You can create this rule directly from a message you've already received.
