Windows 2003, Exchange 2003..... added 2008r2, 2012 r2. Exchange 2010.
Removed Exchange 2003 (with errors - cant specify now).
Raised domain level to 2008r2.
Problems I am getting.. plenty of errors in Event Viewer on new Exchange 2010 box with moved mailboxes etc...
Relating to cant find DC originally, Public Folder Store, Outlook clients cannot get in and then can later.
Getting certificate issues.
Some can get in and some cant. Getting lock ups.
Suspect AD is dirty from an Exchange 2003 removal that had errors and I had to use ADSI also.
This is a small site of 20x going from W2003 and Exch2003 to W2008+W2012 and ExCH2010.
I need to almost restart with Exchange 2010. I have suspicions with the install as services do not appear to auto start every time when the box is rebooted. I cannot get Outlook to open anymore on some users, but can on others after getting password prompts and some with password and untrusted certificates. Suspicions of AD.
Feels like a storm of issues :S.
I am not an Exchange Guru. Think I need to almost start again :).
What guidance please and ASAP as I do have users that need to use OWA, but I keep having to restart Info Store and other services etc... due to Outlook getting locked up
Many thanks in advance
