Backing up Calendar folder or invite mails crashes script

[acashley]

When backing up the Calendar folder or any individual Calendar invite/reply mails in the Inbox, the script crashes. The mailbox in question is an Office 365 mailbox.

Trace example from [Sent Items] folder as follows:

Thanks for the bug report - I'll look into it and get back to you.

Just following up on this one to see if there is any progress? Thanks!

I've released an updated version: 1.2.2, with better logging on failures.
Could you see if that helps pinpoint the problem?

[acashley]

Pulled the updated code and re-ran the job. So far I haven't been able to reproduce this issue.
Not sure if it is successful now because the offending Calendar appointment no longer exists or something else has changed. Lets hope that is the end of it...

I'll close for now.

Please reopen if you get the error again. Also, in that case, please post a sanitized log of the failure.
