Is a 15 GB mailbox enough for your business?

Whether 15 GB is enough depends on message sizes and volume, especially attachments. There is no useful universal message count.

Measure current usage

Check actual storage and recent growth across inbox, sent, archive and deleted folders. Ask the receiving provider how it counts storage before migrating.

Manage large attachments deliberately

Repeated large attachments consume storage quickly. A suitable file-sharing workflow may help, but preserve access controls and required records. Do not delete business correspondence without a retention plan.

Storage is not backup

Capacity does not guarantee recovery from mistakes or account issues. Review provider features and keep independent exports where needed. A 15 GB mailbox does not imply unlimited storage or extra accounts.

Your practical checklist

• Measure usage and growth.
• Check all server folders.
• Plan archiving and backups.
• Confirm provider limits.
