Microsoft 365, set up properly.

Most firms are already on Microsoft 365. Fewer have it configured properly — which is where the security gaps, the licence waste and the daily irritations come from.

Migrated is not finished.

A migration that moves the mailboxes and stops there leaves most of the value on the table and most of the risk in place. Sharing permissions default to something nobody chose, licences are bought for people who left, and the parts that would actually help go unused.

We treat the configuration as the job, not the afterthought: what is shared with whom, what is retained, what is backed up, and what you are paying for.

What this involves.

Microsoft 365 migration

Email, files and accounts moved in a planned sequence with a clear cutover, so the firm keeps working through it.

Configuration and licence review

Sharing, retention and conditional access set deliberately. Licences matched to the people who are actually here.

Private cloud

Where a line-of-business application will not move to a public cloud, we run it on our own servers in secure UK facilities.

Microsoft 365 backup

Microsoft replicates your data. It does not protect you from deletion or ransomware, which is a distinction a lot of firms discover late.

Questions we get asked.

Is Microsoft 365 backed up already?

Not in the way most people assume. Microsoft protects the service; recovering a mailbox or a file set that was deleted, corrupted or encrypted some time ago needs separate backup. We would always add it.

Can our practice software move to the cloud?

Often yes, sometimes only partly. Some legal and accounting applications still expect a server. That is what private cloud and hosted desktops are for.

Will we save money?

Sometimes, particularly on licensing once unused accounts are cleared. We will be straight about it rather than promise savings that do not arrive.
