What should I check when email is missing or will not send?

Before you start

Know the mailbox address and approximate time of the problem.

What to do

1. Check the active mailbox, folders, spam and search filters.
2. For a send problem, inspect the displayed error and whether a Sent copy exists.
3. Check available mailbox quota information or ask the administrator.
4. Report the sender, recipient domain, time and non-sensitive error details through the approved support route.

What happens next

The administrator has information to investigate the affected stage.

If something goes wrong

Do not share the mailbox password or message body publicly. Do not repeatedly resend a confidential message while its outcome is uncertain.
