  1. In my case, this issue is happening due to continuous deletion of mail at my end which resulted in reaching quota of recover deleted items each in Primary Mailbox as well as Online archive. Ask your email Administrator to set your online archive folder to extend automatically. It may take upto 24 hours to effect. In such duration you may not be able copy/move/delete any mails to any folder. The extended portion of the online archive folder can be accessed through Latest IE version 11 or Edge or Chrome.

    Move the mails to Online Archive (Through Outlook Desktop Client) / Personal Archive folder (Through Web browser) to empty space in your mailbox. Depending on the retention policy set by your email Administrator, do not delete or move any mail to local PST folder, to avoid such issues in future. Also, mails older than n number of days may get automatically moved to respective folders in Online Archive, where it will remain until deleted.

    If required local backup, you may copy mails to local PST instead of moving it.
