Important Office 365 limits, quotas and health

We know that security issues can grind your organisation to a halt. There are also other threats to operational continuity that you might not be aware of. It is important to understand Office 365 limits.
There are multiple areas within the 365 system that if not managed correctly can impede business activity. The manual monitoring of all these items is a time consuming and tedious task, it requires automatic monitoring. CatchBefore has multiple checks that are specifically designed to detect and alert to many of the issues below before they become a larger interruption.

Key Items that can destroy continuity:

  1. MailBox quotas. Each email account within 365 has a set storage limit. The limit will depend on the licenses, with higher license levels having more storage space available. If the quota limit is reached, then services will gradually be disabled, until new email can no longer be received or sent.
  2. SharePoint quota. This works slightly differently to individual usage quotes. A base storage allocation is provided tenancy (organisation) wide, with additions to this storage space depending on the number of licenses you have. Hitting the quota in this storage can impact your whole organisation.
  3. OneDrive quotas. Each OneDrive account has a set storage limit. If the quota limit is reached, then additional files will not be able to be added, potentially stopping the user in their tracks.
  4. Expiring Licenses. Licenses typically auto-renew, however if they do not it can have a shutdown effect. It is critical to monitor for licenses that may become suspended or expired.
  5. Restricted Accounts. For various reasons (typically security related), a user account may be restricted in activity. This can have a severe impact on the ability of that user to function (including not being able to receive email).
  6. Domain Name issues. At the heart of your tenancy is normally at least one domain name. If the domain expires or fails to work, then systems that relay on that domain name can grind to a halt.
  7. DNS issues. For each of your domain name, a series of “DNS” servers operates to turn your domain names into numbers that computers understand. If your DNS servers fail to operate correctly, then all other services that rely on your domain name may fail as well, leading to a severe impact to your organisation.
  8. Microsoft Alerts. While not an issue by themselves, they do provide helpful feedback from your tenancy. It is important that these alerts are managed as they can give you a window in to the health of your tenancy, and potentially an opportunity to take early steps to minimise the impact of an issue.
  9. Directory Quota. Each user you add to your tenancy takes up some space (as part of the Directory Quota). There is a limit to the number of entries, if this limit is reached then you may have issues adding more users.
  10. Onsite Sync Status. If you have an on-premises server that is linked to your 365 tenancy, then a regular synchronisation between the system is required to take place. If this fails to operate, then inconsistencies (including password and permissions) may start to appear.
