Can't sign in to Customer Manageer

New Contributor

When I click on the add-in's tab it takes me to the Customer Manager page but says it encountered a problem:


We encountered an error. Please try again.


It asks for me to sign into my Office 365 account.  Either nothing happens or I keep getting this error.

H Doug,


Please check the following points:

1. Go to > Subscriptions > check whether you have the Outlook Customer Manager license.

2. To narrow down the issue, if possible, please check whether OCM can run on a fresh-install computer with Outlook 2016.

3. Did OCM work before? Or, the OCM never run before?




I looked at my subscriptions.  Yes, I have OCM.  It works in Outlook such as when I'm in my inbox and can see activity associated with a contact/email.  But when I click on the tab for add-ins to see the home screen for OCM (Contact / company / Deal, etc.) it won't work.

Here is how it looks in Outlook email.



Hi Doug,


Thanks for your reply.


1. Please go to IE settings > General > Settings under Browsing history > Caches and databases.

2. Delete cache files for the website "".

3. Restart Outlook 2016.

Hi Doug,
