Cannot bind argument to parameter 'String' because it is null.

smtp25gmailcom commented 1 year ago

Im getting this on 3 out of 5 distribution lists migrations it seems. At first I thought it was failed attempts (does this require manual cleanup of removing the guid DL created in EXO?) but its also happening to other DL's never migrated before.

When I ran it as a single migration instead of a batch it would flash on the screen quick about managementobject not found, when running as a batch I think this is still happening its just I cant see it from the logs. I don't have AADConnect on the cmdline so its doing the wait\sleep. (need to resolve ps-remoting issue before aadconnect invoke will work).

Ok - I think this was introduced by a change I took to make multiple migrations more robust.

A few weeks ago we had an issue posted where thread 1 was failing on a large migration. I took a change so that if the group was not deleted after X retries each thread would attempt AD Connect. I think in the multi migration code I failed to account for what happens when you intentionally did not specify an ad connect server.

Give me a minute to look it over but I'm pretty sure that's what's up.

This should be fixed in the version I just released. I put checks in to see if ad connect is in use and if not in use then the test dl function is not called with it and it just loops and waits for deletion rather than try to proactively invoke ad connect.

Hi, I just have the case that it is still happening in version 2.9.7.0. Log can be provided directly, not in public.

Sure I'd love to take a look at these.

Closing this issue.

The root cause is the mail address of the active directory object did not appear on the proxy addresses of the same object. This caused the mail address to not be present in exchange online. In the get-365Distributionlist function the groupSMTPAddress is fed in and then get-o365Recipient is called to get the working recipient. Issue was that this returned an exception that was unhandled. So the call was made, recipient not found, and the variable holding the configuration empty. The script then attempted to output it to the logs which caused an string null exception. New code was added to try catch the recipient capture and then output the exception if it's not found.
