Outlook 365 freezes, will not open.
I have a MS Office 365 subscription which is up to date.

Does this on 2 Windows 10 PCs.


Must use "End Task" in Task Manger to resolve it.

The Icon in Task Manager is a Grey small X in a circle. See attachment.

Any ideas to solve this will be appreciated.
Thanks

Perhaps there's a misbehaving add-in. Open Outlook and check your add-ins. Disable as many add-ins as possible. Re-enable one, and use Outlook for a while. If Outlook runs OK, re-enable another add-in. Continue until you've identified the culprit. Alternatively, you may discover that some of the add-ins are for applications you're no longer using. No need to re-enable those add-ins.
