Its September 2019, and No luck trying to launch OCM. No standard solutions so far.

Occasional Visitor


Lets approach this situation is a very logical manner. For the last two days everything such as the list below has been done, but OCM cannot launch.


1- Clear cache, make sure cache creation is checked in Internet Explorer

2- Tried using alternative browsers such as Edge, Chrome and Firefox

3- Made sure the OCM feature is part of the license

4- Made sure it is part of the Active User.

5 - Manually added the OCM add in from this URL -


Using Windows 10 Pro.  On Outlook Desktop, managed to add-in OCM via the URL


RESULT of al this :

Something went wrong
Please make sure your browser settings allow cache creation.
After this reinstalled Office, but no luck.

Hi hPublish, Under the same Subscription (Office 365 Business Premium), please clarify whether other users are having the same issue or they are workable. This can help check whether this is a specific user issue or something else. Supposing if other users work fine, please let the affected user try on the workable user's machine to see if it makes a difference. Regards, Alan
