Solution

This error is being returned from Outlook via LawMaster and usually relates to Outlook tasks synchronisation. Synchronisation occurs periodically and it updates items from LawMaster Bring-Ups to Outlook tasks and vice versa. The message will appear when LawMaster simultaneously opens Outlook task items past a system-defined limit (Somewhere around 225 to 250). 

If the user in question has a large number of Bring ups then actioning and cleaning them up might resolve the issue. To action a Bring up in LawMaster right click on the Bring up in question and select Action Item:

If this does not resolve the issue then: 

1. and the user doesn't want tasks synced between Outlook and LawMaster as they don't use that functionality then turning the feature off for the user would be best: 
   1. Go to Security > Maintain User Security > "User" > Modify User > Outlook Task Synchronisation: Change this to Disable 
   2. Click OK and then
   3. Close and reopen LawMaster and Outlook on the users machine
      
      
2. and the user does want the syncing functionality:
   1. Increase the time between synchronisation of Bring Ups and tasks for all users to 5 mins or higher: 
      1. Go to Parameters > Set Parameters > Miscellaneous > Outlook Integration 
      2. Click OK
      3. Close and reopen LawMaster and Outlook on the users machine
         
         
         
   2. and there are large number of Bringups for the user and the system is unable to synchronise this many at one time based on what is available under Outllook settings - MaxObjsPerMapiSession.
      
      So we recommend to increase the session limits for the user and see if the error is still an issue. Here is a link to blog from Microsoft that will guide you on how this value can be increased https://docs.microsoft.com/en-us/previous-versions/office/exchange-server-2010/ff477612(v=exchg.141)?redirectedfrom=MSDN
