<![CDATA[Freescout Error when fetching email using Exchange Online since update to v1.8.198]]>I spent a couple of hours trying to troubleshoot this, but at last it appears that there is an issue with Freescout latest release and fetching email from Microsoft exchange-based mailboxes.

Symptoms:

  • Trying to fetching emails from Microsoft Exchange based mailbox returns the following error:
<< * OK The Microsoft Exchange IMAP4 service is ready. (BACKENDAUTHENTICATE) [RgBSADQAUAAyADgAMQBDAEEAMAAzADQAOAAuAEQARQBVAFAAMgA4ADEALgBQAFIATwBEAC4ATwBVAFQATABPAE8ASwAuAEMATwBNAA==]
TAG1 AUTHENTICATE XOAUTH2 .....
<< TAG1 NO AUTHENTICATE failed.

Please see here:

Restoring the app to before the update brings back the fetching of emails.

Might be interesting to put the update on hold/roll back the update until this is solved?

I will certainly contribute if anything meaningful comes up from our side. In the meantime, the issue remains for now (previous version works though.)

The more info the better on such issues.

Our support@ mailbox is on Freescout and it's receiving email just fine.
