mailbox locks deleted aliases for at least 90 days, depending on the age of the account, and this retention period actively protects your privacy.
If you have deleted an alias from your account, you can reactivate it at any time during the retention period. Only once this period has expired can the alias be registered by other users.
You can find the list of deleted aliases in the mailbox Office settings under Email addresses > Email aliases > Deleted aliases. There, you can unblock a deleted alias yourself.
