Outlook Add-in for Skype meeting getting disable after restarting Outlook.

Issue: Outlook Add-in for Lync meeting getting disable after restarting Outlook.

Problem Statement:
Outlook Add-ins gets install automatically when Office 2013 installs (Lync and Skype for Business clients are part of Office package). Add-ins name is Lync Meeting Scheduling Outlook Addin or Skype meeting Add-in for Microsoft Office 2013. Sometime if other add-ins conflict with Outlook add-ins then outlook add-in keep getting disabled. And user has to enable it manually after Outlook restarts. 

By default Lync Meeting Scheduling Outlook Addin or Skype Meeting Add-in for Microsoft Office 2013 installs wit load behavior "Load at Startup". However due to some conflict users Lync or Skype add-ins load behavior get changed to loaded instead of "Load at Startup" had to re-enable Lync Meeting Add-In in each time Outlook 2013 was started as it was not set to "Load at Startup". Look at the below screenshot.
Now question is how we can change load behavior to “Load at Startup”…
You have couple of options to change the Load behavior to startup (Outlook Add-ins, registry and reinstallation etc.)
1.    Start Outlook 2013 as an Administrator (right click on Outlook Icon, run as Administrator)

2.    Outlook > File > Options > Add-ins,

a.     Under Manage: Com Add-Ins click on Go...,  Refer below image

b.    On COM Add-Ins page. Check  Lync Meeting Scheduling Outlook Addin or Skype meeting Add-in for Microsoft Office 2013

c.     Click Remove

d.    OK

3.    Close Outlook.

4.    Now time add add-ins again:

a.     Open Outlook 2013 > File > Options > Add-ins

b.    Under Manage: Com Add-Ins

c.     Click on Go...,

d.    Click on Add...,

e.     Browse path  C:\Program Files (x86)\Microsoft Office\Office15\UCAddin.dll

f.      Click on OK

5.    Close Outlook and start it as a normal user.

6.    Check the Lync Meeting Scheduling Outlook Addin or Skype meeting Add-in for Microsoft Office 2013 add-ins.

This time you will see correct Load Behavior as Load at Startup.

In case issue persist then:

Check Registry key value for Microsoft Office 2010 and Microsoft Office 2013 applications can load add-ins that are registered under HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER.

By default, this entry is set to 3, which specifies that the add-in is loaded at startup.  

1.    Start > Run > Regedit >

2.    HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER\Software\Microsoft\Office\application name\Addins 

If still issue persist then reinstall whole Office package:

Sometime Outlook addins conflict with other application in that case install the Microsoft Office product and Reinstall the same.

1.    Uninstall Microsoft Office 2013.

2.    Uninstall Microsoft Visio 2013.

3.    Install Microsoft Office 2013 and check Outlook add-ins

4.    Then install other office product.

Thank you.
