Enforced Email mailbox size limits starting September
By Army G6
WASHINGTON (Aug 3, 2015) -- Effective Oct. 1, the Defense Information Systems Agency,
or DISA, will enforce existing Department of Defense Enterprise Email, or DEE, Service Level
Agreement, or SLA, mailbox size limits, to lower costs and improve efficiency and Outlook
Each of the Army's more than 1.4 million DEE accounts has a storage limit. Most users fall
into the Basic class, with a maximum storage limit of 512 megabytes. Business class users,
with an operational requirement for a larger storage size, have a maximum storage limit of 4
gigabytes. Previously, those storage limits have not been enforced.
Even without strict enforcement, most Army users have stayed within their maximum
allowable email storage. As of July 31, 2015, however, Army reports indicate that more than
75,000 Army personnel are storing more than 4GB of email. More than 7,700 user mailboxes
exceed 10GB of storage each. That level of heavy use makes for a slow, inefficient and
costly email system for both the individual user and the Army as a whole.
"Using email effectively is one way that today's Army personnel can help reduce costs and
make communications more agile, from the homefront to the tactical edge," said John Howell,
U.S. Army Program Executive Officer Enterprise Information Systems, or PEO EIS, product
director for Enterprise Email, or PD EE. "Each user has a role to play to help facilitate
state-of-the-art access to email from any location, by being mindful of the limits already in
place to reduce costs and launch times."
Clearing out old, outdated emails is good practice for any user. But, what if you aren't already
in the habit? All users at risk of exceeding their size limits will receive auto-generated
warnings when their mailboxes exceed authorized limits. Basic users will receive that warning
if their mailbox exceeds 410 MB of storage, while business users will receive the warning if
their mailbox exceeds 3.7 GB of storage.
"The warning emails serve as a heads-up for users, to remind them to clear out extra emails
before their mailbox size starts to impact their ability to use the email system," said Howell.
"We have resources and information available to help individuals who aren't sure how to get
a handle on their email's storage issues."
If an individual's email storage exceeds its limit--512MB for basic users, and 4GB for
business users-- they will receive a second warning that account will no longer be able to
send email until the extra emails are cleared out. If the email account continues to
grow--beyond 700MB for basic users, or 4.6GB for business users--the user will receive the
third and final warning that the account will also lose its ability to receive incoming mail. At that
point, anyone sending email to the outsized account will receive a non-delivery notification.
It is especially important to note that users can still store everything they were storing before,
just not in their Outlook inbox. Additional email can be stored in personal folders as .pst files
located on local drives or shared drives in accordance with local command policies.
