Mapiex Error - Failed to access Message Store

I'm using the BluePrism Mapiex object to send and get mails, but I'm having the following issue: ERROR: System Exception : Error while sending e-mail:Failure in Send Mail function of Blue Prism Extended MAPI Automation. Failed to access message store I've already tried to open Outlook Client before, open as safe mode and sometimes works, sometimes don't. Scenario: Outlook 2016 Windows 10 Enterprise Blue Prism 5.0.30.0 Mapiex 1.1.15 Exchange E-mail accounts

I have the same issue, how do you resolve it?

Also encountered the same issue. I read from a post in linkedin, logging out and logging in to Outlook may resolved the issue but  unfortunately it did not work for me. Apparently, the profile I was using was not active. Got it resolved by checking the outlook profiles and indicating a correct (active) profile in BP. To check available profiles: Go to Control Panel> Type ""Mail"" in Search box > Mai (32-bit) > Show Profiles Hope this helps.

Had the same problem. Disabling cached exchange mode fixed it for me.
