"Microsoft EXCEL is waiting for another application to complete an OLE action."

My EXCEL/VBA program is attempting to send emails when I receive the following message: "Microsoft EXCEL is waiting for another application to complete an OLE action." There are two options at the bottom of the message "ok" or "cancel," I've tried both but nothing happens - the program just "hangs" (and, I end up having to do a CONTROL, ALT, DELETE to end the task (closing EXCEL). I didn't have this issue prior to yesterday - everything was working fine; however, there seemed to be some change made to Outlook (something about Outlook 2016 on my PC. I looked online and found a few online (you tube) "videos" that provided a remedy which I followed; however, it didn't fix the issue. I tried closing and restarting Outlook, but that didn't help as well. I don't know what to do next/

Hi - no, I shutdown all of my programs and performed a restart and I'm having the same issue.

Hi - davesexcel - I repeated the action that I indicated inmy last response and it worked! I obviously missed something the first time. Thank you for your help!
