<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial",sans-serif">I’ve noticed a situation and I was wondering if anyone else has seen this/has a good idea for a solution.

<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial",sans-serif">I have found over the last year or more that when I send emails from my library account to some lists that some individuals on the lists are not seeing my emails, only the replies
to them from other list members. <u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial",sans-serif"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial",sans-serif">In the two particular cases where I am certain this has happened, both individuals who were not getting the originals were in academic libraries at relatively small colleges.
In one of those two cases, the recipient I know had more general technical knowledge than I do, which makes me think this isn’t just people not knowing how to find their spam folder.

<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial",sans-serif">My email is setup through Microsoft’s Office 365 Educational (I think they call the level “E1”), which is freely available to public libraries level. In the most recent case,
I have looked at least a few blacklist searches for our domain as well as our primary oplin IP address, and both show up as not listed.

<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial",sans-serif">Does anyone have any other thoughts on what is going on, or how to solve this? I know that I could setup a gmail account and everyone would see it, but I hate to dump a portion
of my work communications onto a personal account or maintain multiple work email accounts because of some vagary with O365..
