Microsoft 365 Cleanup
For firms whose Microsoft 365 tenant was built in a hurry and has been growing ever since, and who want it back under control without breaking the way people work on Monday.
A cleanup for a Microsoft 365 tenant that grew before anyone decided how it should work. We tighten Entra ID role assignments, bring SharePoint and OneDrive sharing back under a tenant ceiling that no individual site can exceed, hunt down the Anyone links that let people open files without ever signing in, and give the orphaned Teams sites and stale guest accounts either an owner or an exit. The hardening is governed against the CIS Benchmark for the platform, so what we tighten it to is a published standard rather than a house preference. Nothing moves in production until you have seen the counted list and agreed what goes.

Output
What you walk away with
A defined output, on paper or in your tenant. Yours to use whether the work continues with us or not.
Tenant state report
A counted picture rather than an impression: privileged role holders, external shares broken down by link type, guest accounts, orphaned sites, unused licences, and the mailboxes and OneDrives belonging to people who have already gone.
Identity and sharing tightening
Privileged roles cut back to named people, MFA and sign-in policy made consistent, the tenant sharing ceiling reset, and site-level settings pulled back underneath it.
Link and content remediation
Anyone links reviewed and either expired or replaced with links that require a sign-in, orphaned sites given an owner or archived, and stale guest accounts removed.
Offboarding and retention fix
A real offboarding sequence written down, with the deleted-user OneDrive window set to a number you chose and retention policies covering whatever has to be kept.
How It Works
How the work runs.
A short, defined sequence. Nothing in your tenant or domain changes until the scope and access are confirmed.
Inventory
We pull the numbers first, because a tenant cleanup argued from memory always misses the accounts and shares nobody remembers making.
Impact review
We walk you through what each change would break, agree exclusions for the shares doing real work, and set rollback points.
Staged execution
Teclara applies the approved changes in stages, starting with the lowest-impact changes, and checks key workflows after each stage.
Evidence and handoff
You get a record of every change made, the owner notes, and a review cadence so the tenant does not drift back within a year.
Best Fit
Sound familiar?
Global Administrator has been handed to more people than anyone can now name
Site-level sharing was loosened one request at a time and never tightened back
Anyone links are still live on files that left the firm years ago
Teams sites, groups, and guest accounts are sitting there with no owner and no reason
Leavers still hold licences, mailboxes, and OneDrives that nobody has dealt with
Frequently asked questions.
Who is Microsoft 365 Tenant Cleanup for?
Microsoft 365 Tenant Cleanup is built for firms on Microsoft 365 for two or more years, teams carrying SharePoint and Teams sprawl, and owners whose tenant has never been reviewed.
How does this engagement start?
Every engagement starts with a short first call to confirm the situation, the decision owner, the access required, and whether this is the right engagement for what you actually need.
What happens after the first call?
Teclara confirms the scope, the access, and the timing. If the engagement is a fit, we agree on the work and start. If a different engagement fits better, we say so.
Ready to start?
Book the first call. We will confirm the situation, the access required, and the right way to move forward, with no obligation past that conversation.
