"3. Your server administrator has limited the number of items you can open simultaneously. Try closing messages you have opened or removing attachments and images from unsent messages you are composing " – Getting error when the BOT is running with admin privileges and trying to interact with outlook and iterate a particular folder in mailbox.
With initial troubleshooting we found it may be due to the number/volume of mails in that folder and limited the number of mails, but still need to fix this.
Is it due to some exchange setting or something related to UIRobot and outlook. Please suggest a fix.
