TAG2 LOGOUT on Microsoft Exchange

[freescout-helpdesk]

When connecting via oAuth to Microsoft Exchange Server from time to time we get the following:

>> TAG1 AUTHENTICATE XOAUTH2 dXNlcj...
>> TAG2 LOGOUT
<< OK AUTHENTICATE completed.

<< BYE Microsoft Exchange Server IMAP4 server signing off.

<< OK LOGOUT completed.

When it happens it waits around 30 seconds on TAG1 AUTHENTICATE XOAUTH2 command.
And after some time it's possible to connect again with the same Access Token...

It's strange that TAG2 LOGOUT is called before OK AUTHENTICATE completed

Hi @freescout-helpdesk ,
this looks like a timeout to me. The logout gets always called on __destruct. Given that the OK Auth came afterwards indicates that the call has been aborted before auth could return it's success.

Best regards,

Is it possible to set IMAP connection timeout?

Nevermind. Not a big problem.

Hi @freescout-helpdesk ,
just in case you are still wondering if it is possible; yes it is. At least if you aren't using the legacy mode.

/** @var \Webklex\PHPIMAP\Client $client */
$client->setTimeout(60);
$client->connect();

This would set the timeout to 60 seconds.

Best regards,
