I appreciate that there are no ads here. In recignition of that fact, I became a paid member to support this forum. I do understand that you aren't paid/reimbursed for your work on the site.
I had read the Wiki on the forum software.
Sometimes, due to hosting setups, it's difficult to give admin control to someone for one site, without giving control to other sites. Or, sometimes the hosting people are lazy and/or don't know what they're doing.
After years of running on-prem mail servers, I've migrated several hundred users to Office 365. I'd resisted for a while, seeing the problems with hosted ”solutions”, and with Microsoft's ”solution” in particular. However, the writing was on the wall. I still have numerous Exchange 2013-2016 servers. Sure enough, when problems come up on Office 365, things that would have been simple fixes in an on-prem server take weeks with Office 365, simply because I don't have full control, and the morons at ”support” are barely able to read the instructions in their guide, much less fix anything.
I wonder what the content was of the messages that were lost on the old board.
