All the guides I've found online start with "go to the Tools menu". My problem is that Outlook 2013 will not start at all because it gets stuck at start-up while it tries to load the TeamViewer add-in.
How can I disable the TeamViewer add-in?
you can change the TeamViewer settings to disable the TeamViewer's Outlook addin. Go to options, advance, then disable outlook addin near the bottom of the list.
Start outlook in safe mode: outlook.exe /safe
If you are having problems with a Microsoft Office program, you may be able to use User-Initiated Safe mode to make it possible to run the program.
I read alternatives about running outlook as administrator. The shortcut I had on my taskbar was not a shortcut to Outlook its self, but some meta-information about it. Eventually I found the OUTLOOK.EXE
file somewhere in C:\Program Files
and rick-clicked it and ran it as administrator. That immediately found and disabled the culprit, without even asking me. I assume this is similar to running it in safe mode.
You can rename the TeamViewer add-in files and Outlook will load and show it as inactive. Go to: Program Files (or Program Files (x86))\TeamViewer\Version9\outlook
There are four files in this folder and three of the names start with "TeamViewerMeetingAddIn"
I renamed these by putting 1 as the first character, "1TeamViewerMeetingAddIn"
When I restarted Outlook it loaded up with no problem.
C:\Users\fardelian\AppData\Roaming\Microsoft\AddIns
. Of course fardelian should be the actual username. You can move/delete an add-ons from there to try to disable it.
