The server operation time out .please try again later RRS feed

  • Question

  • Some external users who have a dedicated mailbox database in exchange server started to have the following error :

    “The server operation time out .please try again later “, when pressing forward for  mails with large attachments (9 MB in size) through OWA

    I noticed that this problem occurs with them only as I tried  to access the mail through OWA from outside the company  local network  and  forward this mail with no error ,

    Also I noticed that the database of those users at 9:00 AM to 10: am has a lot of alerts that indicate a  high RPC traffic ,then by monitoring the RPC traffic I found that owa traffic was high ,but after 10 :00 AM even after these alerts are closed and the RPC traffic rate decreased  they  still can’t forward mail with large attachment .and got the same error .

    So does anyone have  any idea about what might be causing the problem,in addition how can I know what make the owa traffic being as high with knowing that this database only have 20 users

  • Hi
       1. please check your firewall setting. Does it scan or audit outside user ?
       2. Mobile phone will cause high traffice.
       3. Do you run any schedule task on your server from 9 A.M to 10 A.M.
       4. Check network flow.

  • Dear Trence,

    thanks for your reply ,I just want to tell you that I have no access on the firewall and I don't think it is the case because I already tried to access the mail from outside and nothing happen with me .

    regarding mobile phone , i was monitoring the rpc traffic and I found that the owa traffic was high not the active sync,

    regarding point 3 I have no schedule

    regarding point 4 how to check the network flow

  • Hi
       1. please check CPU and memory usage of CAS server. Does any service and process contains these ?
       2. Please check virus on client. 
       3. Do you modify setting on your switch and router?

  • about cpu usage : checking the task manager I found that there is no high cpu usage or memory

    antivirus settings  on client was not  changed

    modifying switch or router configuration I don't know because I'm only mail server admin

    but note that when I forward a message with attachment sized 10 MB it would take around 15 to 200 seconds to be loaded internally

    so what do you think I could do

  • Hi
       I would check network. Does anyone download big file? Does server download big patch?
