Your exchange system is probably rejecting emails due to the configured threshold for available disk space ? So your exchange person can’t do a web search ? Have them check the queuers and Transport Logs. Rob Murray From: LISTSERV Site Administrators' Forum <[log in to unmask]> On Behalf Of Jon Schwendemann Sent: September 15, 2022 3:37 PM To: [log in to unmask] Subject: listserv error ⚠External message: Use caution. I am receiving an error in my listserv, that seems to indicate it is an exchange issue. Insufficient system resources (UsedDiskSpace[C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\data\Queue]) I am running on rhel 7.9, with listserv 16.5 Now, of course I could upgrade listserv, but it was doing fine till just the last couple weeks, when this message cropped up. My exchange person doesn’t seem to find anything, so I am wondering if there is something else, on the listserv, that could cause this.
