Unexpected token in IMAP response: '['

[marspd]

Hi there
I'm using Mailkit (from nuget) with an Office365 account and when I try to use the MoveTo method I get the error above. The mail item does get moved successfully.

I'm getting around this at the moment with the copy/delete option.

Excellent code by the way, saved me a whole heap of bother. :-)

In the ImapClient .ctor, you can pass a ProtocolLogger to log the protocol traffic to a stream (or to a text file). Could you do that and paste the "MOVE" command client & server chatter?

I was moving an e-mail from the Inbox to a subfolder under the Inbox called 'Invalid', here is the log

S: A00000010 OK FETCH completed.
C: A00000011 UID MOVE 31 INBOX/Invalid
S: [COPYUID 55 31 6]
S: * 1 EXPUNGE
S: * 0 EXISTS
S: A00000011 OK MOVE completed.

Ugh... Microsoft, read the specifications >_<

The problem is the [COPYUID ...] line which does not follow the specification at all :-\

An example (from the specification) of what that should look like:

   C: a UID MOVE 42:69 foo
   S: * OK [COPYUID 432432 42:69 1202:1229]
   S: * 22 EXPUNGE
   S: (more expunges)
   S: a OK Done

Basically, the [COPYUID ...] line should be preceded by * OK.

The above commit should fix this issue, but I don't have an Office365 account to test against.

If you could let me know if that fixes it, that would be helpful. Thanks!

Microsoft? Standards? Come on, get real. :-) Thanks for the quick fix. I will let you know when I have had a chance to test it. Will this change make it into the nuget package anytime soon or do I need to download the version for github?

[jstedfast]

No problem. I was hoping to have the fix confirmed before making a release to NuGet to avoid having to make another release if my fix doesn't work.

[jstedfast]

I've uploaded 1.0.1 to NuGet. I'm fairly sure my commit will fix this.

[marspd]

I've tested it and it works fine. Thanks for the excellent code and the quick turnaround.

Unexpected COPYUID in IMAP response using folder.MoveTo()

I've also got a similar problem. I'am using MailKit 1.16.0.0.
Trying to move a message from Inbox to another folder with home.pl account. The message is moved but it throws an exception and disconnect.
I've tested with gmail.com account and there is no problem.

In result: ImapProtocolException: 'Syntax error in response. Unexpected token: [atom: COPYUID]'.
Here are logs from gmail.com and home.pl:

Hi @gluszczek

The problem is that the COPYUID response code needs to appear in the OK response line like it does in gmail. It looks like home.pl has a bug in its implementation.

[gluszczek]

Thanks for your reply. Is there any walk around this bug?

[jstedfast]

I think the work-around that I just committed should work.

[gluszczek]

I just tested it and your commit fixed this issue. Thanks!

[jstedfast]

you're welcome!
