We have an issue with the Exchange Mailbox (PowerShell) sensor.
We are using this sensor to get alerted if a specific Mailbox is holding more than a few E-Mails this indicates that a script is not running correctly (sadly this is happening). But PRTG was a lot of help to get us notified.
A few days ago we changed from our old Exchange Server 2010 to a new Exchange Server 2016, after this change we are getting an item count that is a lot higher than before (like 154 more).
Surely we checked the mailbox and there aren’t 154 E-Mails in it. The sensor seems to function, the count goes up and down but the "Item Count" is a bit messed up. Even when this Mailbox is empty we get the "Item Count" from 154.
I also checked other Mailboxes the "Item Count" was different but the result is similar.
Maybe this sensor needs a small adjustment to get the right values from the exchange Server 2016.
Many thanks in advance.
