Microsoft (outlook.office365.com) POP3 timeouts

[glorang]

Hello fellow Znuny users,

Just wanted to check with you if there are any other users who are - since a week or two - receiving intermittent timeouts when popping mailboxes at Microsoft from outlook.office365.com, those are visible as:

Cron email

Code: Select all

Subject: OTRS Scheduler Daemon Cron: MailAccountFetch
Error: Timeout of 600 seconds reached, killing child process!

System log

Code: Select all

Mon Jun 16 10:33:05 2025 (Europe/Brussels)	error	OTRS-otrs.Console.pl-Maint::PostMaster::MailAccountFetch-10	There was an error executing Execute() in Kernel::System::Console::Command::Maint::PostMaster::MailAccountFetch: Error: Timeout of 600 seconds reached, killing child process!
Mon Jun 16 10:22:09 2025 (Europe/Brussels)	error	OTRS-otrs.Console.pl-Maint::PostMaster::MailAccountFetch-10	CommunicationLog(ID:26790591,AccountType:-,AccountID:-,Direction:Incoming,Transport:Email,ObjectLogType:Connection,ObjectLogID:27134297)::Kernel::System::MailAccount::POP3S => POP3S: Can't connect to outlook.office365.com

Communication log

Code: Select all

1		Kernel::System::MailAccount::POP3S	Open connection to 'outlook.office365.com' (xxx@abc.com).	16/06/2025 10:22:09
2		Kernel::System::MailAccount::POP3S	POP3S: Can't connect to outlook.office365.com

Everything works, there is just some delay from time to time on popping the mailbox and a lot of those "MailAccountFetch" mails.

Just checking if it's us or something more general at Microsoft.

Thanks,
Geert
