Hi great tutorial thanks. I have the same kind of problem that I can’t seem to solve: we use an onmicrosoft.com tenant simply to activate Office licences. I have changed the UPN suffix to match the public domain name, dirsync works fine the licences are activated but the connected services (ie save in SharePoint from Word for example, or OneDrive Enterprise) can’t connect (using either the xxx.onmicrosoft.com address or the new one). Any idea about this because I haven’t found any soluton anywhere). Thanks 😉

Yes it’s a weird problem, it’s a shame when you want to align your UPNs with E-mail Addresses or use the E-mail Address as the logon ID and when you have a multi-suffix customer where people move from one company to another and have their E-mail Address changed.
Luckily if you use FIM to replace DIrSync you can plug a PowerShell MA that captures the UPN change and does it properly before the export to the Azure MA tries doing the same. With that, no errors.
