Here are some suggestions for your OWA and EAC issue:ġ. Prerequisites , Prepare Active Directory and domains for Exchange Server
Exchange server 2010 to 2016 install#
Please make sure all prerequisites are satisfied before you install Exchange 2016, and you have prepared AD and domains. What's the detailed version of your Exchange 2010? Only Exchange 2010 SP3 UR11 and later version can coexist with Exchange 2016. I was hoping this error would help someone point me in the right direction to resolve the issue and be able to replace the old server. I tried looking up the error but was unsuccessful.

Exchange server 2010 to 2016 Offline#
With the old server offline I was able to log into the Exchange Admin Center, but as soon as you got past the login screen Last night we had to down the old server to install some patches and I decided to see what happens with the old server offline. During this time many patches have been installed on the server. I shelved it for a while to work on other projects but am back on it now. If I moved the account back to the original servers datastore, I could send and receive again. It would immediately go to the drafts folder. Before moving the active accounts I ran one more test using one of the accounts already moved to the new server.Īt that time I could receive an email but could not send one. Once I had everything setup, I was able to send and receive an email so I moved all inactive accounts to the new server datastore. I followed the insrtuctions step by step on this site. We are replacing a 2008 R2 server running Exchange 2010 with 2016 server and Exchange 2016 CU8.
