Organizing and accessing contact information in Outlook.com
I upgraded today to the 10Gb storage. My storage was 97% full, although as of yet, this has not corrected the problem.
I contacted Microsoft support and they escalated the issue of which I already received a call back from their offices in Washington State. They are calling me back again tomorrow with an update after investigating. They said that with all the changes they have been making with Outlook, this could be a result of that. I will let you know what they come up with.
As for going back to try and salvage my groups from past emails, I cant do that because I have 40 or 50 groups, and I am making changes to those groups on a weekly basis. THEY NEED TO FIX IT !
