What you’re seeing
- The archive mailbox is visible in Outlook, but it is empty or hasn't grown in months.
- The main mailbox keeps getting larger and storage warnings start appearing.
- Older messages that should have moved by now are still sitting in the inbox and other folders.
- Archiving works for some users but not for others.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- No retention policy with a move-to-archive tag is assigned to the mailbox.
- The assigned policy is configured with a long age limit, so little or no mail qualifies yet.
- The background process that applies retention policies hasn't processed the mailbox in a long time.
- The mailbox is on retention hold, which pauses archive processing.
- Personal tags set in Outlook override the default policy for certain folders.
Why it matters
If archiving doesn't run, mailboxes eventually hit their size limit and stop receiving mail entirely. Outlook gets slower as the primary mailbox grows, and local cache files on laptops get larger and more fragile. Companies that pay for archiving as part of their compliance or storage plan are also not getting the benefit they were promised.

Frequently asked questions
Will archived mail still be searchable?
Yes. Archived mail stays in the user's account and can be searched and opened in Outlook and in Outlook on the web; it just doesn't count toward the main mailbox limit.
Does archiving delete anything?
A move-to-archive policy only relocates mail. Deletion policies are separate, and we confirm which policies are in place before making any change.
