Good Day Vasil, thanks a lot for the advice,

The launching of Outlook in safe mode works 100%

If I however launch it normally again then back to the same issue.

Is there a way to manage or view add-in's inside the Outlook Client so that I can go and disable them and try and figure out which one is causing the issue?

Thanks a lot,
Reinhard

Start Outlook in Safe mode and Within Outlook, File>Options>Trust Centre

Disable the COM add-ins one by one and start Outlook in normal mode to check which add-in is causing the problem.

Hi Jackie,

I do not see any COM add-ins under Trust Centre, please help, am I overlooking it...?

Please refer to attached Outlook 2013 Client Trust Center Screen Shot.

Thanks,
Reinhard

It's under File -> Options -> Add-ins. Start by disabling any non-Microsoft ones.

Hi Vasil,

Thanks, I navigated to Add-ins and the only place I can see where one can disable any of them is to choose "Manage: COM Add-ins" and click on "Go..." which I have done and I un-ticked (deselected) the whole bunch, but Outlook still won't open if I then start it normally.

Did I perhaps not disable all Add-ins by the method I used?

See two screen shots attached, thanks.

Thanks,
Reinhard

I noticed that you have Acrobat X installed and it should be the problem.

Acrobat X is not compatible with Office 2013.

Goto Control Panel, click Add/Remove Software, select Adobe Acrobat X, right click Change.

You should see PDFMaker in the list of install option and uncheck it to remove it.

Make sure Outlook 2013 is not running when you do the above.

Hi Jackie,

I have uninstalled the Adobe X Add-in, but unfortunately no luck, Outlook will still not start normally. (see screen shot attached of remaining Add-ins).

So there is no way to simply disable Add-ins, but one has to actually uninstall them one by one from Add/Remove programs in order to find the culprit by process of elimination and it will definitely be an Add-in causing the issue?

Thanks,
Reinhard

You need a repair install of Outlook 2013.

You should be able to use the "Remove" button for non Office add-ins. Try also disabling/removing the TeamViewer and Change notifier addins. The Search one should also not be needed.

ASKER

Hi Vasil,

There is no "remove" button or option under Add-ins (see screen shot attached).

I do also notice that most Add-ins are already under the "Inactive Application Add-Ins" or "Disabled Application Add-Ins", it is only the Microsoft VBA for Microsoft Outlook Addin that is still enabled, but should not cause any issue I guess.

@ Jackie, I did also run a "Repair" on Office from Add/Remove Programs, but still no luck with Outlook starting normally.

Reinhard

Sorry. I have made a mistake.

It is a problem of Win 10 OS.

Try to run system restore to the restore point from the latest window update.

There is if you select COM add-ins press the Go button :)

ASKER

Hi Vasil,

Ahhhhh, thank you :) I see that indeed there is a remove button...

I did try and remove the Add-ins but it won't allow me even though I am a Local Administrator of my Computer, not sure how it could refuse the remove of Add-ins?

Thanks,
Reinhard

Well, ignore the Search one then. Does disabling all the others help? Have you also tried disabling any AV/scanning software, they usually have modules that "capture" emails and are known to cause issues.

ASKER

Hi Vasil,

All of the Add-ins give the same message, it won't let me remove them.

I did also unload my TrendMicro OfficeScan Anti-Virus Client to test, but this also did not make any difference.

So at this point the struggle is to get the Add-ins removed in order to test and see if that makes a difference.

Regards,
Reinhard

Well I guess you can remove them manually from the registry, under HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addin

It's probably easier to test with a new user profile on that machine though.

It is a problem of Win 10 OS.

You can try to create a new user profile in Windows. If the problem still exists, you need to do a repair install of the OS.
