In a recent Office 365 project, I came across an issue where,\u00a0if we migrated a user’s Exchange\u00a02013 mailbox to\u00a0Exchange Online before we\u00a0migrated their Lync 2013 user to Skype for Business Online,\u00a0the Move-CsUser<\/code> cmdlet\u00a0generated an error:<\/p>\n

This is described in Camille de Bay’s blog post<\/a>\u00a0and appears to be related to the Unified Contact Store, which is enabled by default with Lync 2013 and\u00a0Exchange 2013. \u00a0There appear to be two options:<\/p>\n

    \n
  1. Migrate Lync before Exchange<\/li>\n
  2. Use the -force<\/code> switch\u00a0with the Move-CsUser<\/code> cmdlet\u00a0(which will result in a loss of contacts)<\/li>\n<\/ol>\n

    Dave Stork goes on to describe some issues with a\u00a0combination of the UCS, Lync\u00a0on-premises and Exchange Online<\/a>\u00a0(and these appeared to apply to my Lync 2013\/Skype for Business Online hybrid solution<\/a>\u00a0too).<\/p>\n
