My business has a small office of 5 computers and our email access is vital on a daily basis as we receive orders and other important details, from a range of companies.
The problem started a couple of months ago when for some reason we weren't receiving emails for around 2 or 3 hours then they all come flying in together later in the day, now it's becoming more regular (almost every day) and for longer periods of time. I have spent too much of my time looking into this problem which is conflicting with my work, so far I have:
- Spoken to the company that hosts our domain, in turn they have contacted the "hosting" company to check for discrepancies with the server, errors between sender to server to us, the white list...nothing appears to be wrong.
- Spoken to my ISP, no issues with the internet, no result.
- Checked the server settings incoming and outgoing, there is definitely no issue there as at some point we do receive the emails.
- Checked for sufficient storage on the server.
I have never come across anything like it, generally errors sending and receiving can be resolved without a problem and being an IT professional I find this very annoying, and I will not believe that this is any trafficking issue as we haven't had this problem for years.
I am in the middle of moving to a new premises with new computers, new ISP and all the rest, but until the move date this needs to be fixed, it's creating serious issues. Any suggestions would highly be appreciated. Please let me know if you require additional information.
EDIT: There are no rules set in the account settings, the OWA doesn't hold the emails. Another company I work alongside with (local) has had a similar problem but on rarer occasions.
