Mail oddness

[schwartze]

I am using Mail.app and have been since I moved to this computer (about a year now) with no problems. I get mail on two accounts, both IMAP, one is from an Exchange server.

Two things have been happening that are odd...

1. This one has been happening for a bit - I can't use the delete icon to delete messages. It is forever greyed out. I must highlight and hit the delete key to delete messages.

2. this just started this morning - messages are not being marked read. well some of them are, and some aren't, so some are not being marked read, or more precisly they are still marked new. Now, I have the preview turned off, so I know when I have read them, because i have to click on them to read them.

Any thoughts?

Extra info... The trash and sent items are cleared daily. The messages saved on the computer (not on the servers) is only totaling 17 megabytes...

Any more info needed, just let me know.
