Been having quite a time upgrading 2013 C2R Office installations to Office 2016 in an environment with some mixed msi installations of visio/project on the side.
Been having several installs now where I can remove all previous Office installations ok, and the installation of 2016 completes ok, but I can’t get outlook to open properly. I’ve had at least a couple of these, and I’ve tried deleting all old outlook profiles and creating a fresh profile to connect to office 365. I can create the profile ok, but outlook won’t load (it gets stuck somewhere during the splash screen).
I read something about telemetry logs for Office 2013 but wasn’t able to locate those for 2016 – I wonder if it is possible to see more detailed startup logs for outlook (what it’s doing during splash)? Also, it seemed both of my problem cases were unable to start outlook in safe mode – they claim outlook/office has a problem that needs to be repaired, but the repair simply fails.
I wonder if this means there are still remains of old Office installations on the computer causing this, even though everything at least superficially seems to be removed? I thought about checking for addons in the registry and disabling them from there when writing this, but i doubt that’s the root cause of the issue when outlook won’t even start in safe mode. It seems the problem is somehow related to the office install although it completes without issues.
I suspect running Office 2013 removal tool (the Microsoft fixit thing) has not been the best option, as it has at least had problems with mixed msi/c2r installs in that it first only removes msi installs and then refuses to remove the c2r install by re-running, unless first running an uninstall (that will fail) through control panel for the c2r and THEN re-run the uninstallation tool. Therefore i also suspect this may have something to do with the uninstall tool not properly really removing everything it should have.
Anyone had issues like this or have a clue where to dig for more detailed logs of Outlook 2016 startup problems?
