\/><\/a><\/p>\n<h2>What Microsoft Identity Manager Did for Your Organization<\/h2>\n<p data-start=\"61\" data-end=\"249\">Microsoft Identity Manager sat between your directories and apps like a quiet traffic controller. It watched for changes, figured out what mattered, and pushed updates based on your rules.<\/p>\n<p data-start=\"251\" data-end=\"427\">In multi-forest AD, it gave everyone a shared, consistent view of coworkers. It created and updated users and contacts so titles, numbers, and emails stayed aligned everywhere.<\/p>\n<p data-start=\"429\" data-end=\"510\">It also fed Exchange so contacts and calendars reached mailboxes and then phones.<\/p>\n<p data-start=\"512\" data-end=\"691\">When someone joined, moved, or left, MIM pushed those updates wherever you set it to go. Most teams used it mainly for this directory plumbing, not the advanced workflow features.<\/p>\n<p data-start=\"693\" data-end=\"798\" data-is-last-node=\"\" data-is-only-node=\"\">Because it handled those basics, people could find and contact each other without even thinking about it.<\/p>\n<h2>Why Chasing a Direct MIM Replacement Can Backfire<\/h2>\n<p data-start=\"58\" data-end=\"134\">When teams first react to MIM\u2019s end of support, a familiar pattern kicks in.<\/p>\n<p data-start=\"136\" data-end=\"277\">Someone says, \u201cWe need the new MIM,\u201d and suddenly everyone is searching for a tool that claims to handle every connector, rule, and scenario.<\/p>\n<p data-start=\"279\" data-end=\"344\">You end up planning another big, general-purpose identity engine.<\/p>\n<p data-start=\"346\" data-end=\"554\">On paper, it feels safe, but in practice, it leads to more design workshops, more custom logic, and another complex platform only a few people truly understand. The product changes, but the risk stays the same.<\/p>\n<p data-start=\"556\" data-end=\"654\">The real issue is that this skips a basic question: which specific outcomes do we need to protect?<\/p>\n<p data-start=\"656\" data-end=\"723\">For many multi-forest environments, the outcome is straightforward.<\/p>\n<p data-start=\"725\" data-end=\"913\">People in Forest A need to easily find and reach people in Forest B, in Outlook, and on their phones. Accurate contacts and working calendars matter more than replicating every MIM feature.<\/p>\n<p data-start=\"915\" data-end=\"1016\">With that lens, \u201cidentity and access\u201d becomes one trac,k and \u201ccontacts and calendars\u201d becomes another.<\/p>\n<p data-start=\"1018\" data-end=\"1090\" data-is-last-node=\"\" data-is-only-node=\"\">You don\u2019t have to solve everything with one massive replacement project.<\/p>\n<h2 data-start=\"733\" data-end=\"927\">How CSOP Handles Contacts and Calendars After MIM<\/h2>\n<p><span data-contrast=\"auto\">After you peel back everything around MIM, the everyday pain looks like this:<\/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<ul>\n<li aria-setsize=\"-1\" data-leveltext=\"\uf0b7\" data-font=\"Symbol\" data-listid=\"5\" data-list-defn-props=\"{&quot;335552541&quot;:1,&quot;335559685&quot;:720,&quot;335559991&quot;:360,&quot;469769226&quot;:&quot;Symbol&quot;,&quot;469769242&quot;:[8226],&quot;469777803&quot;:&quot;left&quot;,&quot;469777804&quot;:&quot;\uf0b7&quot;,&quot;469777815&quot;:&quot;hybridMultilevel&quot;}\" data-aria-posinset=\"1\" data-aria-level=\"1\"><span data-contrast=\"auto\">Can users still search the GAL and find anyone they need?<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/li>\n<\/ul>\n<ul>\n<li aria-setsize=\"-1\" data-leveltext=\"\uf0b7\" data-font=\"Symbol\" data-listid=\"5\" data-list-defn-props=\"{&quot;335552541&quot;:1,&quot;335559685&quot;:720,&quot;335559991&quot;:360,&quot;469769226&quot;:&quot;Symbol&quot;,&quot;469769242&quot;:[8226],&quot;469777803&quot;:&quot;left&quot;,&quot;469777804&quot;:&quot;\uf0b7&quot;,&quot;469777815&quot;:&quot;hybridMultilevel&quot;}\" data-aria-posinset=\"2\" data-aria-level=\"1\"><span data-contrast=\"auto\">Do phones show the right internal numbers without manual imports?<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/li>\n<\/ul>\n<ul>\n<li aria-setsize=\"-1\" data-leveltext=\"\uf0b7\" data-font=\"Symbol\" data-listid=\"5\" data-list-defn-props=\"{&quot;335552541&quot;:1,&quot;335559685&quot;:720,&quot;335559991&quot;:360,&quot;469769226&quot;:&quot;Symbol&quot;,&quot;469769242&quot;:[8226],&quot;469777803&quot;:&quot;left&quot;,&quot;469777804&quot;:&quot;\uf0b7&quot;,&quot;469777815&quot;:&quot;hybridMultilevel&quot;}\" data-aria-posinset=\"3\" data-aria-level=\"1\"><span data-contrast=\"auto\">Can teams in different forests rely on each other\u2019s calendars?<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/li>\n<\/ul>\n<p><a href=\"https:\/\/csop.cirasync.com\/\"><span data-contrast=\"none\">CiraSync Server On Premise<\/span><\/a><span data-contrast=\"auto\"> (CSOP) focuses on those questions.<\/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\">CSOP connects to your existing AD and Exchange forests and builds contact sets from the sources you choose.
