Hi, I use multiple mailboxes with Office 365 and one of these will not open. The others open fine it's just one that wont open. I get the blue icon with the letter coming out of the envelope. It's happened a few time and seems to clear it's self after a few hours. Is there anyway to force it to clear the error? Thanks in advance for your help.
