After removing the imap accounts from ubuntu -> settings -> online accounts, evolution starts up and works with my exchange and google account. (Both defined in online accounts)

After trying to add an imap account on the online accounts, evolution was again unable to start up.
If I try to add the account within evolution, it will crash either at checking authentication credentials or after seting up account and test it.

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
