This problem has been going on for weeks now. I've twice talked to BT help and just been told it's a known issue and that there were various problems with the changeover to the Microsoft 365 platform, of which, presumably this is one,that Microsoft was working to fix.
It seems to be intermittent; sometimes when I log on I can delete messages, other times I can't. When that happened it was also refusing to let me log out, though that hasn't recurred for a few days. It has no relationship to which computer I use; I've logged into my account on other people's computers and had the same problem.
This has gone on far too long, and it seems to me that subscribers to BT business broadband are not being given a basic part of the service they are paying so much for and that, until it is fixed, a rebate is in order. The present situation is just not good enough. (I don't have AVG anti-virus so the possible solution posted above is, unfortunately, irrelevant. In any case, as I say above, the issue seems to be account-linked and not specific to any one computer.)
So come on, BT. What are you going to do about it?
