Hi,
I have a process running 12h a day, accessing emails in Outlook. I noticed that using “Get Outloook Mail Messages” throws error after some time.
I tested it in while loop, accessing every 5s, and here are the results


Only fix is to restart Outlook. Increasing delay allows more accesses but never more than 100.
Windows Servoer 2012R2

Microsoft Outlook 2010 32 bit
Happy hunting
