We recently decided to go towards O365. During the initial deployment I installed the AzureADConnect Program and set it up. Now all my AD Users are in the Office Portal (and the AzureAD).
BUT my user is double. In Hindsight that makes sense, as I had an account First.Lastname@company.com on the account before. now I have that account (which is from AzureAD) and First.Lastname0815@companycom.onmicrosoft.com, which is from my on-prem AD.
Any idea how to fix that? I deleted the AzureAD-Account, and hoped, that Azure would re-sync correctly.
I tried to delete the "wrong" Azure-AD Account, to have it re-synced, but I can not do that (as it states that it is synced from a local server)
Google did not give me an idea, as I am not exactly sure what to look for :-/
