When migrating the outlook metabot v2 (perform various outlook operations) from v11 to a360 we came up with a new problem.
Some tasks (getreceivedtime, downloadattachments, forwardmail, replymail,...) generate errors like below:
When using predefined task:'session' expecting 'DLLSessionClosable' received 'DLLSessionClosable'
When using open/close dll: System.ArgumentNullException: Value cannot be null. at OutlookWrapper.OutlookWrapper.GetReceivedTime()
Reading mails is no problem.
Before using M365 this was not a problem.
What could cause this? And how to solve? I looked at multiple posts, but did not find solution there...
