Dear Maintainer,

I encountered a problem while creating an Office 365 account. I went to
Edit->Preferences->Mail Accounts->Add and entered the following configurations:

Server type: Exchange Web Services
username: tvtuovin@ad.helsinki.fi
host url: https://outlook.office365.com/EWS/Exchange.asmx
-> Fetch URL

Everything seemed to work but the account did not appear on the list. I tried
this several times and closed and reopended the Evolution also without success.
After my attemts I found some Evolution back processes with ps -ef | grep
evolution and killed those. After that I restarted Evolution and now the
accounts that I had created and all of them started to fetch new mail but it
did not seem to work and evolution would hang if I clicked any of the accounts
on the list on the left. After restarting Evolution I was able to re-enter
Edit->Preferences and I tried deleting the extra accounts. The account would
disappear from the list but Evolution would hang again and after restart the
account would still be on the list.

I was able to resolve all the above issues by installing evolution-mapi package.

So it seems that at least with Office 365 accounts the evolution-ews package
requires the evolution-mapi package.

After a conversation with jelmer on IRC, it seems that this issue
might not be related to -mapi after all.

That being said, it is still clearly extant, even in the version in
sid.  I don't experience a hang; the Evolution client opens, but it
refuses to actually add an EWS account.

I note, `evolution --force-shutdown` seems to make the accounts appear,
despite multiple attempts of stopping and starting evolution normally
having no effect.
