Hello

Environment:  
PHP 7.4.33  
Apache/2.4.52 (Ubuntu)  
MySQL or MariaDB 5.5.5-10.6.12-MariaDB-0ubuntu0.22.04.1  
Current version of Dolibarr (Programs) 18.0.4

I am setting up dolibarr, and I want to configure the collector.  
The collector is with M365 & Oauth2.

When the mailbox is empty, the collector connects and tells me that no mail is available.  
When an email is present, I get an error 500.

The apache logs :  
[Fri Jan 26 16:46:56.730294 2024] [php7:error] [pid 1556] [client 192.168.99.11:56251] PHP Fatal error: Uncaught Error: Object of class Webklex\PHPIMAP\Message could not be converted to string in /usr/share/dolibarr/htdocs/emailcollec

Do you have an idea for a correction?

Hi Tjeanneau,  
i have exact the same problem, i was experimenting with a new installation inkl. 19 Beta with PHP 8.1, the problem must be somwhere in PHP 7 or 8, the problems continue when collecting, it wont move the mail into archiv.  
I will be patient and wait for the final Version 19.
