Hello. I have outlook straight up disabling the addin even after I have performed all the fixes in this thread. It still disabling it.
The only thing is what should the entry be for : HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Outlook\Addins\OnePlaceMail ..
I found no load behaviour entry (?)

Thank you for the update Christina.
Great to hear its all sorted!

kind regards
Elissa

Hi Elissa,

No worries, I was able to re-install the add in by doing the following:

1. Uninstall OnePlaceMail from add/remove programs.
2. Open the registry
3. Navigate to Computer\HKEY_CURRENT_USER
4. Do a Find (edit > find) for OnePlaceMail and delete all registry entries found that is associated with OnePlaceMail. Keep searching for OnePlaceMail until you reach the end of the HKEY_CURRENT_USER section.
5. Re-install OnePlaceMail
6. Launch Outlook and now OnePlaceMail add in is available again.

Thank you!!

Hi Christina

Apologies, I missed your response. Can you please email support@oneplacesolutions.com and we can set up a screenshare to get the addin back in Outlook.

Kind regards

Hi Elissa,
I tried several times to uninstall and re-install OnePlaceMail from Control Panel add/remove programs.
I also tried uninstalling OPM, delete the OnePlaceSolution folders from the Program Files location and AppData locations, then running a repair on MS Office, rebooting and then re-installing OPM.

For some reason it just does not want to add it back into Outlook, not even listed.

Hi Christina

Thanks for the update. Can you please try to uninstall the addin via Control Panel & reinstall it again?

If that does not sort it out, please let us know!

kind regards

Elissa

Thank you for replying so quickly! I actually exported both of those registry entries from another machine to the one that is having the issue since they were missing the entries completely, however the add in still does not appear in the list as an option to enable it.

Is there another way to add the add-in back into Outlook?

Hey Christina

Thanks for getting in touch. You can check the load behaviour in registry at the following location:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins\OnePlaceMail

here, can you please confirm the load behaviour is set to '3'?

If this is correct, can you please also check

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Outlook\Addins\OnePlaceMail

Please let me know how you go.

Thanks,
Elissa

How can you re-add the OnePlaceMail add-in? I deleted it because it remained in inactive status even when enabling the add-in. I thought re-installing OnePlaceMail would bring the addin back, however after the install completed, the add-in still did not come back. I re-added registry entries by getting them from another system, however it still did not add the add-in back in Outlook. Using Outlook 2016.
