OTRS can't fetch mails normally from Exchange server

[changhelry]

Hi,

I 'm use OTRS 3.0.8 and fetch mails from Exchange server 2010 by POP3. But sometimes the OTRS can't fetch mails normally. the logs are as below. I checked the OTRS and the exchange web mailbox , found that it seems that the Exchange can't delete the mails read by OTRS in time , it causes more and more mails accumulated in mailbox. But if I change another mail client tool to fetch mails from the noc account , the mails will be deleted very soon. Is there an issue in OTRS fetching mails from POP3? or I need to configure some more parameters in OTRS ? please help on this

Thanks
Justin

You may want to decrease the frequency of collecting from Exchange, especially if you have lots of tickets or multiple attachments.

I tried to decrease the frequency ,but it does not work very well. Could you give more suggestion?


In the otrs.PostMasterMailbox.log , sometimes shows

Sounds like something else is also grabbing email. you may want to make sure your processes are only running once and no other box is competing for the email.

The webmail of the mailbox is open when the OTRS gets mails from POP3, will it impact the OTRS fetching mails? The web mail only read the mails.

and what's problem of "

No human should ever touch the otrs mailbox, including reading it. Where do you think the webmail gets the email you see? Yes, it impacts POP3.

Your System Time is in a nonstandard format. (should be something like: Wed, 18 Jul 2012 12:33:17 GMT)
For instance, your year is after the time? After that, I can't necessarily help you. Create a bug report.
