hotmail problem emailing from my mobile, htc wildfire s

I've been having a lot of problems with the lack of storage capacity on my mobile but cannot keep up with the deleting as it is very slow, after trawling through Orange for months and following instructions and then onto HTC themselves and following every suggestion, and going through all the storage sync facility apps such as google play and evernote etc which cannot be used at this point in time due to lack of room to upload, so going through mob found had forward email capacity checked with htc and yes I had this available all the time so tried and didn't work all day, back to both hyc and Orange and Bt and they've all said no problem their end so it comes down to hotmail problem not accepting emails from phone, my mob keeps breaking, I need it desperately so please could anyone help me?
