A relationship manager dials a number that was reassigned last quarter. A deal team spends the first week of an integration asking who sits where. An analyst cannot find the new compliance contact on a phone. Each gap looks small, and each one costs time when the work cannot wait.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">The cause is usually the same. Contact data lives in Microsoft 365, while the phones, shared mailboxes, and second tenants that need it get updated by hand, if they get updated at all.

We built CiraSync to automate that work inside the Microsoft 365 environment these firms already trust.<\/span><span
