Outlook add-ins are programs that run within Outlook and perform actions that Outlook doesn’t provide. Since add-ins are separate programs, occasionally an Outlook add-in can encounter problems, especially after a Office Update. This article shows how to fix the problem.
1.Re-enable Add-ins
• With Outlook open, click File.
* Click Options
* Click on Add-ins
* Make sure the add-ins program is listed in Active Application Add-ins.
* If the Add-ins program is not listed in Active Application Add-ins. Click Go in Manage: COM Add-ins.
* Check the programs you wan to add. For example, OneOutlook is for CRM.
* If you don’t see the Program in COM Add-ins, change the Manager to Disabled Item and then click Go.
* In the Disabled Items, highlight the item you want to use and then click on Enable.
2. Fix Disabled Add-ins
* If you see ADD-INS PROBLEM A problem was detected with an add-in and it has been disabled, click on View Disabled Add-ins, or View More details.
